I really like your channel, You give clear concise instruction and often include the valuable lesson on why it's done that way.

I have been cursing straight pipe threads since I arrived in Argentina. The most common plumbing system is polyethylene pipe with straight pipe threads. It is sort of sealed by using 10 to 20 wraps of Teflon tape. Hemp used to be used a lot but now not do much. There are also some liquid sealers but I haven't had much luck with them.
As a plumbing teacher, I enjoy your videos and have made up many worksheets to go along with them. They work well, especially with remote learning! Thanks for doing these!
excellent video. as a retired electrician, i worked alongside plumbers, seen their work, but never fully understood why they installed the way they did.
threads have an inherent leakage path. the flanks do not create a seal. instead ALL theaded connections have a helical leakage path. You'll strip the threads long before you ever jam them tight enough to prevent leaks. PTFE and dope serve 2 functions. 1: prevents parts from rusting together. 2: fills/clogs the leakage path around the threads.
@@richardhodds7812 I put lots of pipes together with just the thread cutting oil - and no leaks. If there is a small leak, just tighten some more and it stops.
An older female have learned how-to thanks to the sharing knowledge from these persons. I’ve become totally dependent to gauge if I can or to call them expensive professional s.
Hello sir, Thanks for enlightening our knowledge,I would like to know can we use teflon tape for high pressure and high temperature application?if yes which type of ptfe tape to be use??? I would be very thankfull for the information you will provide
How about a video on the how's and why of the 2 different threads on angle stop valves. It seems that over the past 30 years the 1/2 compression side of the valve that attaches to a copper stub out has changed from fine threads to coarse threads
I started repair service in 1986 and discovered the same issue. The actual compression size is 5/8 inch, but some manufacturers used a pipe thread instead of a standard compression thread resulting in the issues you noticed. If you run into a pipe thread compression fitting, the best bet is to use a puller to remove the pipe thread compression nut and start over with a proper fine thread compression fitting.
And never use pipe dope on the threads because this will cause you to possibly over tighten and split the compression nut. In the instructions says you can you can add 1 drop of oil but when the nut becomes hand tight, only tighten the nut half turn more and stop. I’ve seen many over tightened and split because of pipe dope on the threads.
Around the 1:30 mark you show the root and crest of the threads at the same location. The root should be shown at the base of the “V” of the thread. I still enjoy your videos. Thanks for making them.
To add to this, crests are always at the peak, and roots in the valley, regardless of whether they are external or internal. Your illustration is not entirely correct. Flats exist on both the internal and external forms. Since NPT threads are intended for low pressure, low heat applications, the tolerances on the crests, roots, and flanks (pitch diameters) are quite liberal. When manufactured at one extreme, when the parts are assembled, the crests and roots contact each other and that is the increase in torque that you feel. Further tightening causes these areas to crush until the flanks come into contact. Theoretically, this gives you a "dryseal" fit. At the other extreme, the flanks come together first, and no amount of tightening fills the voids at the crests and roots. This is what the tape, dope, or lubricant is primarily used for. Lubricating and anti-seize are secondary benefits. Since these compounds are inherently weak, they are unacceptable for high pressure/high heat or caustic chemical applications. There are Dryseal threads for this, such as NPTF. I was on the ANSI/ASME standards committees that design and regulate these various forms. Dave
@@Got2Learn the distance that the threads go into the fitting. like if I had a face to face measurement from one 90 to another 90, how much would i have to add to account for the pipe going into the fittings

@Common Sense Realist 577 doesn't harden to the best of my knowledge. Stays kinda 'goey' when I had to remove parts sealed only with this. Works perfectly even on a wet / pressurised system when in a pinch and saves you from faffing around trying to find the beginning of the thread when it's taped with PTFE which is not ideal whilst being sprayed with water at 3 bar...
@@EthosEater I'm 58 and have been doing it my way most of those years with great success. The reason "they" say not to do that is because it will force a little pipe dope beyond the threads into the pipe. But you are supposed to flush the lines anyway.
I ran into a homeowners brother from far eastern Europe who said they used to fix everything with string and grease. In the US we used graphite and string. Hemp isn’t far off the mark. Anything that will allow the threads to move and tighten and fill gaps might work. Do not use ANY of these (except an anti-seize/lubricant) on straight threads that are designed to work with a gasket or a compression fitting.
I use a lot of schedule 80 barbed fittings with 1 side male thread usually 1.5" and 2" size. Sometimes but not always the fitting will say right on it " USE NO PIPE DOPE". Can you explain this a bit more. I am not sure what to do here so I just tape it. An example would be a 2" barbed fitting threading into a 2" galvanized Tee. Thank you so much for your enlightenment!!!
In Europe, Whitworth threads are used for plumbing. Exactly British Standard Pipe. BSPP = parallel, BSPT = tapered. BSP can be confused with NTP. The flanks are 55°, not 60° as with NTP or metric threads. There are tapered and straight threads. Straigth threads need a seal as shown.

All fire sprinkler joints in Australia are sealed with hemp and soap. We havent caught up to the rest of the world yet. But the hemp works, is cheap and rarely leaks
That is the same in many parts of the world as hemp has different properties that make it a better sealant than PTFE-tape for some applications. Another example would be gas-pipes: In some countries (and parts of the US) it is not allowed to use PTFE-tape to seal the gas-pipes of residential buildings.
I used NPT female threaded shark bit fittings to repair the leak on top of my water heater. I believe they are tapered thread (bought at Lowe's). If I continue tightening them will they eventually stop the "seeping" leak or will they break?
What about threads for steam? I have old piping and several leaks to fix in threaded connections once heating season is done. Should I use brush on stuff from the hardware store or is there a secret for threads with steam?
Hi, I have a fitting , its a PVC union and its not threaded the entire way to match what I have to put it on. Can I put a thick washer into the void and just go with it? Any ideas would be helpful
Thanks for video. If possible could you add european threads. Getting stuck trying to fit G 1/2 thread shower head to NPT. I wished sellers on Amazon would say hey, our parts does not fit on U.S. showers. Great video...while looking for video on how to solve fittings.
Make sure the PVC male adapter is schedule 80. Screw it into a fitting or coupling using a bit of Teflon tape. If you are careful, you can also use a bit of pipe dope as well
I’ve been using teflon tape with the wrong premise. Thanks for correcting me. Problem is a lot of accessories with straight threads come with Teflon tape which is why I use it everywhere when plumbing. I also use alot tapering the layers. I’m guessing this is wrong? I do this so I can position fittings otherwise the tightness where it won’t leak is in the wrong position.
I am a retired machinist that cut all kinds of threads on a lathe - Acme, left hand, double lead etc. Now as a handyman plumber I find these video informative. You might have mentioned that sometimes the taper and strait are used together. EXAMPLE: Flexible water heater connectors they are straight pipe female with a rubber seal. They are coupled to a tapered thread male nipple on the water heater. Correct?
Damn, I was hoping you'd cover some higher pressure and wider term range fittings like JIC/AN, O-ring boss, compression fittings, etc. I work with mostly high pressure nitrogen and medium to high pressure pressure liquid oxygen systems and am always on the lookout for good intro material to show new people. Sadly this excludes NPT and NPS as they aren't suited for cryo.
@@aaronpops4108 I understand that but how can a company higher an individual off the street to install water softeners that has no certification in order to touch potable lines. Company's should only be allowed to hire license plumbers to install equipment like softeners and R.Os.
@@chuckandkelly oh, in that case I guess it would be kind of like an apprenticeship. I don't know the exact legalities, but usually a non-licensed person can do the work under the supervision of a journeyman plumber.
I have a question, does anyone know of pipe dope for gas that DOES NOT set off an electric gas sniffer? The pipe dope I use says for liquids and gas. But if you put your cordless gas sniffer to it, it sets off the alarm. I have tried many different kinds and ALL say for water, liquids and gas, and do the same thing!
@@Got2Learn when I was apprenticing 20 years ago I couldn't figure out why my gas fittings kept setting off the alarm. I finally just opened the can and stuck the sniffer up to it and it went off. So all those leaks I thought I had I really didn't have. I went back and tested them with liquid gas tester.
Great video! If I may add, we call straight threads a running thread. They are a result of letting the pipe die run down the length of a pipe. ..of course, the leading few threads will be tapered so typically, you would run it on a piece of pipe longer than you need and cut off the tapered threads. Also, if you've ever bought some of that seemingly all thread tubing thats used in lamps and such. ..its basically threaded conduit. I've used it in 3/8" and 1/2" diameters but that's not what they are. You'll never get a nut with NC or NF threads to screw onto them because they're actually 1/8 and 1/4 (respectively) pipe threads. ..and who came up with the sizing on pipe threads? ..maybe there's a schedule of pipe where it all makes sense. Oh, ..and don't forget about the British pipe size. If you want to pipe any high pressure air, like from a SCUBA or SCBA tank to use to charge a paintball marker or a PCP air rifle, those fittings are usually in British pipe sizes. They're the same goofy diameters as NPT but the threads are slightly off.
Please let me know if you’ve ever had to try and convince someone that, NPT and HPT are different? I went round and round with a man once trying to explain it to him, who asked me if they were the same, I told him no, but he didn’t believe me, a day later we ran into each other again and he said you were right. I said Mr. I wouldn’t steer you wrong, I was just trying to help you out.
Hello, I always wonder how you can keep a good seal but still position the threaded object (for example a faucet) in the right position. When you screw it very tight, the faucet may end up on its head, so unscrew it a bit, but that does losen the seal doesn’t it. Thats why hemp is good, it swells up, but the other solutions don’t, so i am confused.
Leaking threads on a cabin build... Tape goop tight af loose. shark bite to pex pex is great. Just get a slow by persistent water bubble that grows untill it drips.
Here's a Idea for a video and a question. I was sitting here thinking for pvc, pex, and copper pipes, there's alot of screw in pieces now.. So what if someone used Taps and Dies to create their own threads and do their whole pipe system that way rather than soldering, glueing, or crimping? It would be easy to replace a piece ( i mean pex already is easy but gets costly when you need a bunch of fittings.) I would assume thought you have to use NPT, as NPS you would have a hard time figuring out had to add a O ring to pipes especially if your not one of those people that know everything about all things tool and creation wise. It would be interesting and it seems like it would be cheaper than any of the already existing methods.
Bravo!! Very informative. Do you have any content regarding the Vacuum Relief Valve on residential hot water tanks?? I just came across one that was weeping from the slot in the valve and I had some trouble trying to get information...
Michael Lewis Honestly, I didn't know what the weeping fitting was on the gas fired hot water tank!! At my parent's property. Turns out I never had one on the hot water tank (electric) at my house which lead to my confusion. I'll need to address this on my tank.

Another example would be gas-pipes: In some countries (and parts of the US) it is not allowed to use PTFE-tape to seal the gas-pipes of residential buildings.
Are NPS threads the same as electrical rigid conduit threads? Seems like no one can tell me what
rigid conduit threads are.
Personally, I don't know...but maybe someone here boes as a lot are electricians, just give it some time ;)
when threading rigid conduit you can use a plumbers die, just thread back far enough to accomondate locknuts & bushings.
Pretty informative and makes sense. Am I the only one that noticed the Teflon tape applied in the wrong direction?
No, that was the first thing I noticed
I used NPT female threaded shark bit fittings to repair the leak on top of my water heater. I believe they are tapered thread (bought at Lowe's). If I continue tightening them will they eventually stop the "seeping" leak or will they break?
Might break, better undo it and inspect, might already be cracked.
What about threads for steam? I have old piping and several leaks to fix in threaded connections once heating season is done. Should I use brush on stuff from the hardware store or is there a secret for threads with steam?
You can use pink teflon no problem.
Hi, I have a fitting , its a PVC union and its not threaded the entire way to match what I have to put it on. Can I put a thick washer into the void and just go with it? Any ideas would be helpful
@Got2Learn YOU HAVE A FANTASTIC CHANNEL 👍👍👍 and the best tutorials with detailed instructions, and they are always so informative...
Thank you sooooo much!!!
simple and awesome explanation
Thank you 🙂
Great video
Very informative 👍🏼👍🏼
Glad it was helpful!!!
Thanks for video. If possible could you add european threads. Getting stuck trying to fit G 1/2 thread shower head to NPT. I wished sellers on Amazon would say hey, our parts does not fit on U.S. showers. Great video...while looking for video on how to solve fittings.
Ok how do you connect pictures schedule 40 to galvanized pipe with threads?
Pictures?
Do you mean fixtures?
@@sainttrilby7171 🤣
Make sure the PVC male adapter is schedule 80. Screw it into a fitting or coupling using a bit of Teflon tape. If you are careful, you can also use a bit of pipe dope as well
Or just use dope.
Awesome! Thank you so much for the detail.
My pleasure!
I’ve been using teflon tape with the wrong premise. Thanks for correcting me. Problem is a lot of accessories with straight threads come with Teflon tape which is why I use it everywhere when plumbing. I also use alot tapering the layers. I’m guessing this is wrong? I do this so I can position fittings otherwise the tightness where it won’t leak is in the wrong position.
I am a retired machinist that cut all kinds of threads on a lathe - Acme, left hand, double lead etc. Now as a handyman plumber I find these video informative. You might have mentioned that sometimes the taper and strait are used together. EXAMPLE: Flexible water heater connectors they are straight pipe female with a rubber seal. They are coupled to a tapered thread male nipple on the water heater. Correct?
Thanks! The straight threads are connected to straight threads with an oring, gasket or flared connection, and tapered just by friction.
Those are straight threads?
Dont worry about the NPT or NPS thing. Plumbing epoxy makes it all seal perfectly every time.
What? No.
@@guymross I think sarcasm.
I’m a retired machinist I used to make all these treads all the time all different sizes up to 4 inches stainless steel.
That's crazy man musta been fun 🤟
Lots of fun stuff.
I bet 👍
Damn, I was hoping you'd cover some higher pressure and wider term range fittings like JIC/AN, O-ring boss, compression fittings, etc. I work with mostly high pressure nitrogen and medium to high pressure pressure liquid oxygen systems and am always on the lookout for good intro material to show new people. Sadly this excludes NPT and NPS as they aren't suited for cryo.
Hi, would you have any recommendations for intro material for plumbinbg of high pressure cryogenics? I had no idea NPT is not cryo rated!
You are sharing such a wealth of information!! Thank you, my friend.
You are most welcome, please share if you can, it helps the channel tremendously ✌✌
Is there a law in Canada that says a person needs to be certified to work on potable waterlines?
I believe that a home owner can work on his own plumbing, as long as a permit is obtained and an inspection is done.
💯
@@aaronpops4108 I understand that but how can a company higher an individual off the street to install water softeners that has no certification in order to touch potable lines. Company's should only be allowed to hire license plumbers to install equipment like softeners and R.Os.
@@chuckandkelly oh, in that case I guess it would be kind of like an apprenticeship. I don't know the exact legalities, but usually a non-licensed person can do the work under the supervision of a journeyman plumber.
Hi, great video BUT 2:03- after those great videos that You made we already know, that the thread is taping in wrong side :D
Yes, that was my mistake explaining it to my animation guy, my bad...good eye Pawel ;)

I have a question, does anyone know of pipe dope for gas that DOES NOT set off an electric gas sniffer? The pipe dope I use says for liquids and gas. But if you put your cordless gas sniffer to it, it sets off the alarm. I have tried many different kinds and ALL say for water, liquids and gas, and do the same thing!
Interesting, i'm sure someone here knows.
@@Got2Learn when I was apprenticing 20 years ago I couldn't figure out why my gas fittings kept setting off the alarm. I finally just opened the can and stuck the sniffer up to it and it went off. So all those leaks I thought I had I really didn't have. I went back and tested them with liquid gas tester.
😬😬😬
Ever hear of permabond? Good sticky stuff that can be used for any liquid or gas connections. Maximum pipe size is 2 inches.
@@georei no never heard of it. Where can you get it? Is it permanent? Some dope is adhesive.
Thank you for another excellent educational tutorial.
I learn a lot from your well produced videos.
You are most welcome, please share if you can, it helps the channel tremendously ✌✌
Great video... but NPT stands for both “National Pipe Thread” and “National Pipe Taper”? Who thought that up???
Heheee, let's not get into that 😉
Great video! If I may add, we call straight threads a running thread. They are a result of letting the pipe die run down the length of a pipe. ..of course, the leading few threads will be tapered so typically, you would run it on a piece of pipe longer than you need and cut off the tapered threads. Also, if you've ever bought some of that seemingly all thread tubing thats used in lamps and such. ..its basically threaded conduit. I've used it in 3/8" and 1/2" diameters but that's not what they are. You'll never get a nut with NC or NF threads to screw onto them because they're actually 1/8 and 1/4 (respectively) pipe threads. ..and who came up with the sizing on pipe threads? ..maybe there's a schedule of pipe where it all makes sense.
Oh, ..and don't forget about the British pipe size. If you want to pipe any high pressure air, like from a SCUBA or SCBA tank to use to charge a paintball marker or a PCP air rifle, those fittings are usually in British pipe sizes. They're the same goofy diameters as NPT but the threads are slightly off.
Good info, thanks!!! 🙏
What thread type for an electrical conduit?
Please let me know if you’ve ever had to try and convince someone that, NPT and HPT are different? I went round and round with a man once trying to explain it to him, who asked me if they were the same, I told him no, but he didn’t believe me, a day later we ran into each other again and he said you were right. I said Mr. I wouldn’t steer you wrong, I was just trying to help you out.
From the title, I was hoping there would be some information about thread sizes (diameter and pitch) as well.
Awesome as always.
You are most welcome, please share if you can, it helps the channel tremendously ✌✌
Hello, I always wonder how you can keep a good seal but still position the threaded object (for example a faucet) in the right position. When you screw it very tight, the faucet may end up on its head, so unscrew it a bit, but that does losen the seal doesn’t it. Thats why hemp is good, it swells up, but the other solutions don’t, so i am confused.
You tighten until there's one full turn left and use that turn to position accordingly
Definitely harder to find NPS. Anyone know where I can purchase a NPS (NPSM) 1" Female x 1" Sweat fittings? Installing a Phyn flow sensor.
Leaking threads on a cabin build... Tape goop tight af loose. shark bite to pex pex is great. Just get a slow by persistent water bubble that grows untill it drips.
little tape lots of tape not too tight. super tight.
Great info! Thanks!
You bet!
Good job 👍
🙏🙏🙏
Learning from your channel everyday. Thanks. From a starting plumber
🙏🙏🙏
Here's a Idea for a video and a question. I was sitting here thinking for pvc, pex, and copper pipes, there's alot of screw in pieces now.. So what if someone used Taps and Dies to create their own threads and do their whole pipe system that way rather than soldering, glueing, or crimping? It would be easy to replace a piece ( i mean pex already is easy but gets costly when you need a bunch of fittings.) I would assume thought you have to use NPT, as NPS you would have a hard time figuring out had to add a O ring to pipes especially if your not one of those people that know everything about all things tool and creation wise. It would be interesting and it seems like it would be cheaper than any of the already existing methods.
For smaller or wider teeth, what are their name n purpose?
Nice one!

Bravo!! Very informative.
Do you have any content regarding the Vacuum Relief Valve on residential hot water tanks?? I just came across one that was weeping from the slot in the valve and I had some trouble trying to get information...
Thank you so much!
Unfortunately, I do not, not yet 😩
Why not just replace the valve and move on?
Michael Lewis Honestly, I didn't know what the weeping fitting was on the gas fired hot water tank!! At my parent's property.
Turns out I never had one on the hot water tank (electric) at my house which lead to my confusion. I'll need to address this on my tank.
@@MarioDallaRiva gotcha. They are super cheap and easy to replace so it seems like a non issue.
@@michaellewis6569 Thanks, Michael! Yeah, they’re around $20 here in Canada.
We use loctite pipe thread in the uk
Industry standard unless they are cheap

Question @G2L. How long do you have to be an apprentice plumber in Canada before you become a journeyman and also at what point can you take the red seal exam?
4 years, after 4 years, you can do your exam.

@@Got2Learn Hey man. Here in ireland we use alot of compression and soldering fittings. I once sen a compression fitting with no olive and it still made a watertight joint.
Fucking weird!
Love the tips and tricks of your videos and keep em coming. 👍 Also we mostly bend copper tube to make everything flow to wherever as easy as possible. I have to admit I think it looks and works better.... personally for me that is.
@@fionnan2811happy awesome, thank you so much!!!
@@Got2Learn Neat trick also. If you were short an o-ring you could use bubble gum as a seal and I've tested it to 10,000psi with hydraulic pressure.
Love to see you incorporate that into your videos. If you ever do let me know as I'm out plumbing and might not see the video.
Just a tip and trick.
Works for water also.
Used it on a machine one day as a last resort and it worked.
I thought it was a one off but tried again and got the same result in different fluids and air.
You should send me your address so I can send you a pipeslice as its in imperial here in ireland also. They are very fast for cutting copper and there is a different wheel for stainless steel but I can't afford to send both. But I think you will be very surprised how fast it will cut hard copper and soft copper.👍 And u can use my name and it will benefit me for work here in the countryside.
Just let me know as I have one here that I can post today!
Why doesn't a male 3/4inch garden hose screw on to a 3/4 inch brass female ball valve
The combination only screws on one 3ed of a turn by hand
Like, from 12 o'clock to 4 o'clock
Nice video! ... do you think you can do a video on pex a and pex b along with fittings . Also can I use fitting for pex a only and put on a pex b pipe ?
Thanks!
I think PEX-a pipe can be use with PEX-b fitiings without problems but maybe there will be warranty issues, not sure.
