I've been applying Teflon tape the wrong way my entire life! I've been using it as a contraceptive all this time. Thanks for teaching me how to use it the right way, Roger.
I’m currently a jeweler and it’s been great but I’m ready to make a change to plumbing and I’ve been studying and watching your videos for months now thank you for your knowledge based out of tx im trying to find apprenticeship.
I'm not a plumber, just a regular guy, I didn't know that there were different types of Tef Tape. Earlier this year, I had a valve go bad on my gas stove, it was leaking gas. I don't know how to replace the valve, so I called a handi-man who quoted me 500. A new stove was just 100 more, so that's what I went with and did the job myself. Came with a new flexible gas pipe extension and some yellow tef tape. I didn't know that there were differences and I'm glad I used the right stuff.
@@jmobbinfoo4838, that, I didn't know, came with the kit with the stove, so I just assumed. I did spray some soap and water on the connection and didn't get any bubbles, plus I don't smell gas anymore, so, maybe I'm okay?
@@Hellcat71782, I have no idea how to fix a stove, doesn't mean I can't replace one. I can't fix cars either, that doesn't stop me from going to the dealer and signing for another
Man, I was sweating watching this video at the thought that I may have been applying Teflon tape wrong for the last 30 years. I wasn't. 😂 Enjoyed the vid.
An engineer for a company that manufactures mini split AC units told me to use dope on flair fittings. He said it doesn’t directly seal the fitting, but it lubricates and allows you to tighten the fitting easier.
Nice video, good information for everyone. I try and keep rolls all over the house but that stuff just seems to walk off on its own when SHTF. I also keep a bar of Ivory soap in the bathroom cabinet for emergency temp fixes, just scrape that on pipe threads and it works very well, just don't leave it there forever.
I’ve seen tape on supply line to faucets a lot in apartment maintenance. I even had one faucet that they used plumbers grease on the lines and made a mess of everything! Thanks Roger!
In the olden days of my youth (lol not that long ago but if you're young reading this yes years and years ago) my grandfather would never let me use teflon on brass to brass fittings. But, back then, the threads would come threaded right so you had the right seal and fitting to where the brass basically sealed itself. That's not these days though, as well, the same people aren't the ones making modern parts. Now I always run thr fittings in and out as far as I can back and fourth so I know if I gotta use a tap/dye or if I just need a bit of liquid teflon. I only use the liquid teflon for brass as it's easier to clean up and make look good once the joint is sealed.
That's how ALL pipe thread threads are designed. They actually seal through deformation. The tape only needs a layer or two and you should be wrenching those joints home. The problem is so few people understand that the threads seal by deformation. So they use more tape, more dope, etc
@ObservationofLimits I can't tell you how many times it was such an easy fix back when I was actively doing it. So many just a quarter turn away from stopping it themselves. But they're scared of stripping the threads. We used to thread our own pipe for galvanized and black iron pipe. If they can strip those threads they have my awe. They don't understand how strong the tapper can be when withholding pressure.
I know a whole company of commercial plumbers that agrees with pretty much all this stuff. We use yellow for gas (it's thicker and inspectors like it) but blue monster for everything else. 3-4 wraps.
Hey Roger, could you do a video on the difference between applying the tape flat vs twisting the tape and applying it in between the threads? My building inspector wanted me to twist the tape instead of laying it flat. My thought process on flat vs twisted is that the threads are actually sealed when the connection is made. Like you would potentially have microscopic gaps between the threaded connections that laying the tape flat would fix.
How many wraps would you say is good for non tapered pipe threads, the europeans use? I have truck mounted crane from a company called Fassi(italy) and they use straight threads in their hydraulic tanks, we always seem to have a slow drip no matter what we do
How do you eliminate the leaking and scale on galvanized or copper to brass valves on water lines such as the main house shut off or washing machine valves?
For me (not a plumber), I've found that if I always hold the fitting in my right hand I never put it on in the wrong direction. It's easier to roll your wrist away from your body than towards it. So the tape is always winding clockwise. Once you decide what works for you, never deviate.
I like using Teflon thread sealing compound on top of the tape, as well as a little dab on the backside of the flare to lubricate the nut as it gets tightened. Also a dab on the compression ring when using compression fittings. I have also used it on trailer tires where the rim bead is so rusted I put a coating of pipe thread sealant and it would seal up the tire bead perfectly.
Using pipe sealant on top of teflon tape is a waste, it accomplishes nothing. Teflon tape is a sealant/lubricant in itself, and especially when you put pipe sealant on top of the tape, it's only sealing one side of the threads, not both. Use pipe sealant OR teflon, never both. I prefer Loctite Pipe Sealant with Teflon #592. Hand tight plus 1/4 turn and it will seal to pipe burst strength. I've been using it for 40+ years and NEVER had a leak. Seriously.
The other problem with letting tape hang over the hole... If you have valves, drip legs, etc. you can really screw up a hydraulic system getting tape bits in it.
@@ObservationofLimits If it works for the application who cares? You wanna sit there just hanking on it like a gorilla or do you want to pop a few drops of extra sealant on it and be done with it without extra unnecessary physical exertion?
Roger, I remember when we only had pipe dope or what is now called pipe thrid compound long before Teflon tape came alone. Now i see plumbers using both. What is going on?
Use your telfon tape. I learned my lesson not using one on my hose nozzle that now broken. But come to unscrew the nozzle, it has completely seized up. I have to replace the whole hose because of a broken nozzle head.
PTFE tape is something of the past for metal-metal threads, that we keep for applications with very low or no pressure. It works of course, but it has very low tolerance if a fitting should ever become loose by even a single degree. To avoid this some added thread sealant in association with PTFE tape. Or we still use hemp fibers with sealing grease for something even more reliable. But today, thread sealing cord is the way to go for metal-metal threads, it has all the advantages without the drawbacks of other methods.
I love when I see it on a braided supply line. Like there a rubber washer... Your just making it harder to tighten all the way to the washer. Lol and stop pipe dopeing p traps..
Never ever use tape on male threads going into female PVC fittings. It may seal very well but can lead to the female PVC fitting cracking sometime later. Use Teflon dope instead in that case. Tape is great when used correctly in the right situations.
never use pipe dope on plastic to plastic threads just teflon.....use use the hell out of pipe dope on everything else.... it enrages me when i see tape being used on compression fittings....NPT people. plumber 36yrs.
Most plumbers today don't even bother with Teflon tape. In fact, many faucets, shower heads, etc. now specifically say on the packaging to NOT use teflon tape with them because it can cause leaks.

Wow $500…glad you had the drive to do it yourself 💪🏻
You shouldn't use any tape on gas connectio, only use pipe dope.

So you have no idea what you’re doing yet you are doing gas repairs? I hope I live about 5-6 states away from you

Sometimes the simplest knowledge, is the best. This is one example

The correct application for for flare fittings is to use nylog to seal the connection.....

The blue teflon tastes the best
Respect the monster
I generally use the teflon thread compound goop. Easy and reliable.
Gasoila is the best. The OG soft set. Rated to like 10,000 psi @ 600F.
You can also use JB weld or blue loctite
Correction at 1:18 wrapping the tape the wrong way .
😅
Someone needs to teach this stock footage actor a thing or two about plumbing…
Great vid. Why is the second hand in your watch broken.????
How many wraps would you say is good for non tapered pipe threads, the europeans use? I have truck mounted crane from a company called Fassi(italy) and they use straight threads in their hydraulic tanks, we always seem to have a slow drip no matter what we do
I use the Blue Monster, and being left handed, putting it on correctly feels natural, if it doesn't, I'm going the wrong direction!

What color tape for air compressor lines (hoses).
I typically use white with no problem, but I've seen blue tape recommended.
I only do three wraps with the blue tape. I’ve cracked brass valves with too much tape.
The other problem with letting tape hang over the hole... If you have valves, drip legs, etc. you can really screw up a hydraulic system getting tape bits in it.
Very true, than can cause some damage…
If I had a dollar for everytime I saw pipe dope, or ptfe on a flare joint, I'd go on vacation right now.
I use 3 wraps of blue monster tape and then put a layer of blue monster thread sealant......no leaks.
So you put lube on your lube because your wrists are weak?
@@ObservationofLimits If it works for the application who cares? You wanna sit there just hanking on it like a gorilla or do you want to pop a few drops of extra sealant on it and be done with it without extra unnecessary physical exertion?
Hey, Jack Leg put the tape over the sealant
At 9:34 wrapping the tape the wrong way.
And at 1:15ish
Lol
I’m just saying pipe dope with tape in it is faster and easier and works great tape can easily un screw
Roger, I remember when we only had pipe dope or what is now called pipe thrid compound long before Teflon tape came alone. Now i see plumbers using both. What is going on?
Better safe than sorry.

Huh! I went to the store to buy some Teflon tape. I couldn’t find any. I did find PTFE tape, though. I’m doubting this guy. Lol
Nice toothbrush!
Thanks! I'd prefer it be soft bristles...They are a little rough
A good old thread paste is faster.
Almost a 10 minute video to perform a 30 second job. LOL!

Plumber here. Teflon on gas is illegal in my area. ONLY can you use a "gas" teflon if you REALLY NEED IT.
Most inspectors will fail you.
I use thread tape and pipe dope (industrial setting), but I don't pipe dope threads before putting on teflon tape that's ridiculous!
Or just Use PTFE liquid over here in the future
Deady

I use tape of pipe dope
Fun fact, before the invention of teflon tape they used horse's hair (som still do!).
I heard about that recently! Very cool
I use dental floss
How many wraps?!😅
never use pipe dope on plastic to plastic threads just teflon.....use use the hell out of pipe dope on everything else.... it enrages me when i see tape being used on compression fittings....NPT people. plumber 36yrs.
0:54 oh yeah, cross thread the s*** out of that thing
I pipe dope and tape.
tell us something we don't know
Most plumbers today don't even bother with Teflon tape. In fact, many faucets, shower heads, etc. now specifically say on the packaging to NOT use teflon tape with them because it can cause leaks.
yup they come with gaskets instead of
Meh. 🫤 I’m a pipe dope man.
