How I Seal/ Install Threaded Water Pipe Fittings Line Up Boiler Pipe Fittings

- I go over how I seal threaded water pipe fittings. I’m connecting threaded black pipe. I first clean off threads on black pipe. Next I wrap Teflon tape clockwise around threads. After the Teflon I apply a small amount of pipe dope. Now the pipe can be threaded into fitting. I am finishing the supply line off my boiler. When tightening threaded pipe, never back out the pipe, turning to the left. Once the water pipe or gas pipe rotates left, a gap breaks the seal. Therefore this pipe connection will leak. Any time pipe turned to left, take the pipe apart. Then clean up and reseal the thread.
When tightening an airtight threaded pipe connection. Always stop before the angle you want to connect pipes. Tightening the threaded pipe connection this way allows you to tighten the pipe into the correct spot. If you over turn the threaded pipe fitting, this fitting must be removed and resealed.
Threaded pipe connections do not need to be tighten to where it no longer can rotate. You will feel good resistance and that connection is sealed. Any kind of threaded pipe seals the same way.

guy is spot on here great work
BRILLIANT WORK!!!
everybodys got there own way but there is a right way,you should always use 2 wrenches
Do you have a brand/model gauge you recommend? I want to put one on my return side.
Good work 👍
awesome Bro,,,, thank a punch!!!!
How would you fit something at 7 bar pressure?
Great video. One of the only videos that shows how to work with the pipe for boilers. I need to replace a Bell & Gossett flow control valve and wasn't sure how to manage when turning one side unscrews the other. Seeing you connect to the boiler now things make sense. Do you have to cut and thread the pipe yourself or does it come like that already? Thank you!
Haha love this guy
It's a good thing we can't hear the threads screaming in pain as you go that last time around.
They will survive. I can not back it off so need to get it in position tightening it
@@howtohvac3234 You can with hemp and paste. Using teflon for somthing like this is just a waste of money and qualety.
This the only dope i'm on you know what I am saying! LOL!!!
Weekend plumber here. This video helped answer some questions. BUT...what happens if that "one last turn" won't go all the way around again? How do you adjust? Do you remove it, re-tape and re-dope it, add more tape this time, and then try again?
Try to not go for the last turn. If you noticed when I was putting pipe together I stopped before where the pipe should be. Then when I connect and need to adjust angle I am still tightening. If you go until it gets stuck, yes it needs to come off and get resealed. The pipe doesn't need to be overtightened. All my connections might even make another complete turn with enough force. Yet over tightening can create a leak. Here is a video I am doing some black piping. This is my main channel where I am doing actual service calls. ruclips.net/video/P6mTdu6-iBA/видео.html
Good stuff. Can you do video on hydronic piping and stuff?
I was planing on videos going over components and how to install parts. Is that what your looking for?
@@howtohvac3234 yes but also include like how to properly pipe supply and return and expansion tank etc.
Protip: No, the PTFE tapes are not all the same and they have different applications. Never become this guy. Knowledge is power.
Maybe 50 years ago as an apprentice our electric shop had a set of so called electrical dies for Rigid 1/2 to 2" stock & dies. A mechanic insisted on borrowing them to thread several pieces of schedule 40 pipe for 125# steam line. I tried to explain that only the sparkies were supposed to use them but he said that I was a no nothing first month apprentice. So he used them and had a leak, he applied the pipe dope & Teflon tape then had another leak, then another leak. Finally our chief electrician told him that the first month apprentice apparently knows more about threading steam.pipe then him.After that we painted them bright orange. Like to have a dollar for every piece of rigid conduit that I threaded.
The does need to be tapered not just to make threads: different dies used. Mine can be used on a hand threaded or a power threader
What kind of pump is that?
Grundfus alpha 15-55F came off a boiler replacement I did not too long ago
Never trust a tech who wears flip flops with socks…..
I have alignment problems with threaded pipes 😭
Were you able to complete the project?
I’m installing a pipe, when I tighten one end it loosens the other end
And when I tighten that end, it loosens the end I just tightened.
Wtf!!
Use a union
hacker is the best hacker ever !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
What’s good rip1202
@@howtohvac3234 I love tape then, Dope !!!!!!!!!!!!!!! Just like you !!!!!!!!!!!!!!! Always great vidjas !!!!!!!!!!!!!!
How about you tell us more about that boiler dude
I will be doing many vids on my boiler
Struggle bus. Left loosy righty tighty lol. Them wrenches are way to clean.
Don’t think you do that work often
I do this work often. If you think I don’t you should check out my other channel. The HVAC hacker
That pumps on the wrong side of the system. Gotta read the install book. Lookup Dan Houlihan "pumping away".
Pumps on the correct side of system. Your looking at the primary pump. The secondary pumps are pumping away.
How to hack HVAC 🤡
WRONG never use tape and pipe dope, pipe dope needs to contact the metal threads for it to work and if you use tape and pipe dope the pipe dope won't contact the metal threads on one side.
Wrong, it's not a never are always answer. North Carolina office of the state fire marshal and engineering division for instance requires what the instructions on the tape used are. If tape says no dope, then no dope, if tape says may be used with dope, then it may be both. Some states, counties, and cities require that teflon tape and pipe dope be used together for plumbing pipes and natural gas lines in all residential homes. Some states, counties, and cities require use of only one.
@@Reloadeez you were taught wrong
@7587 Once again it depends on the code, hacks like you don't follow code.
@@Reloadeez if they is a code to use tape and paste it should be illegal.
@@Reloadeez post the law link and i will have it removed.
This video didn’t help with shit
