Thank you for the instruction. Had a problem with a fitting of a water pipe that wouldn't stop leaking. Couldn't get it fixed with the teflon tape. The hemp and paste, with your instruction, worked like a dream!
I reviewed a lot of similar videos, but your video was for me a REVELATION!!! ... These brilliant 45 degrees - technology breakthrough, so gracefully, solves many problems with scrolling flax, with an excess of flax, this is exactly what I needed. After each sealing up pipe joints I will respectfully remember You !!!!
The paste is applied over the hemp usually. Its for anti rust or too much grip in case you'll have to unscrew in future. Hemp is wonderful. On water pipes gets swollen and seals the threads. Teflon is junk !
In France in most case (except for gaz and air) we use oakum and paste because it's 100% leak proof if it's well-made and you can turn your fitting a bit if you made a mistake it won't leak . All the plumbers I know use this method. Anyway everybody's free to work his own way some prefer Teflon, other prefer past and oakum, some like scelent... Peace 🙏 PS: you don't need to break the thread on galvanise steel pipe and black iron pipe. Only brass fitting need it.
As a cabinet maker I need to join some pipes from time to time usually when I make kitchens. I have been using Teflon tape for years, but this last time the pipe just wouldn't stop making drops and I made three reattempts. I'm going to try this way tomorrow. PS One of the reasons I use Teflon is the drop in pipe quality and that a colleague of mine cracked the pipe with using too much threads.
Get rectorseal tru blue pipe dope, as it is a sealant. Put a thin layer of pipe dope on the threads. Then wrap in teflon. Then apply another layer of pipe dope. This should do the trick.
very good. im a master plumber in teas and just finish a big job in isreal. they do it almost the same but put the hemp on first and then tephlon tap after because some valves there cannot work if any pipe dope enters the valve
Is that REGULAR hemp, as in ANY hemp ROPE, or TWINE, which I can buy anywhere hemp rope or twine is sold? Or is it a type of hemp that's made specifically for plumbing thread sealer? My hardware stores and big-box stores do not sell any type of hemp or lamp wick that's specifically made for sealing NPT pipes -- only the teflon tape and dope.
Make sure to start with the hemp, and from the end of the pipe. Make sure no hemp goes inside the pipe. Then, afterwards, apply the paste on top of the hemp.
A plumber told me he knows if a DIY'er did a job like this because they used thread tape and not hemp and they have leaking joints. He explained that the water actually swells the hemp and seals the joint. Thread tape is used on the inside of a female nut connector as well as the hemp on the male threads.
No it should go clockwise as well, and be careful that you end the hemp at the end of the thread, so the joint can catch the hemp as it turns and not leak.
very interesting. Been dealing with a very slight, yet very stubborn weep. I was wondering why there's no taper on the threads here in Finland, and every joint is made up with hemp.
One of my senior fitter tought me one hack, how to seal BSP threads used in water piping. Apply oil paint & wound cotton thread (which is used in grossary shops) in BSP threads to give strong & leakproof joint.
His thread was loose . You should be only able to spin a fitting 4.5 times before it's (hand tight) ... Not all the way to the last thread ever . That's why they are tapered .
I'm unsure about the paste. The hemp expands once it gets wet, sealing the joint. Won't the paste inhibit the wetting of the hemp? I've always done it without paste.
Hi, Thanks for a great video, I had tried to make a joint myself and I know that it is wrong. However I thought that the hemp has to be fully wetted before applying to the pipe by drawing it through a blob of paste. What do you think. I would like to get the further details from the email that is mentioned in the video.
EntropyDivideByZero Eight years late! But I will give my answer :) I attended plumbing school in Denmark for a short while, and we did a lot of these installations in school. We did not wet the hemp, and I dont see a good reason to do it. The hemp is easier to work with when clean and dry. You want to stretch the "lump" of hemp into a long one. Ie make the same lumb reach many turns around the thread. I think that will be much harder to do if its greased up first. The layer is relatively thin so I think the paste will penetrate sufficiently without any effort.
sorry but you apply the hemp incorrectly. You mislead people as such with incomplete sealing that is bound to leak way sooner than it should. When you separated like that (1:24) you destroyed the parallel position of the fibers and messed it up. Fibers should be completely clean and neat, just as they are when you buy it. That way it will follow naturally the pipe threading and will not end up knoting in there and get pushed out as you tight up the joint. Also the hemp piece should be pulled out when turned on the threads so it will be tight and not rotate with the female threads. If its not messed up, its not easy to break when pulled, so you can apply some force on the pulling while threading it.
Now that is a true sealent! I do have issues with that application. Okay, the hemp swells up when it's hit by moisture, just like in a lead joint. What happens when the hemp deteriorates? Redo the whole system? I can not believe that plumbers in Europe use non tapering threads. Maybe in the former eastern bloc, where it was difficult to get proper fittings. But Germany? I doubt it.
Why not using Teflon tape? Is using an organic fibre such as mentioned in combination with a mineral sealer safe for consumption? Imagine all that stuff getting into your drinking water ?
So this video is around 4 minutes long. On a typical job on a typical day I can do at least 16 make ups in less than 4 minutes that all hold 200psi test pressure. Teflon tape and paste on tapered threads. I have no idea why they hold on to this archaic method. 57 seconds ago
This guy is clearly not a professionel, you can tell by the way he handles the materiales. A professional plumber will do the same fitting in less than 30sec... See instruktions video on unipak.dk

Thanks for this helpfull video. I'll redo my joints tomorrow following your advices. This will do. Thx from Luxembourg

Very nicely explained and demonstrated thank you.
Great job!
Some say to take the hacksaw and make little burrs on the thread for the hemp to grab onto.

bruh that a lot of pipes that aren't to code 😢
Great! Just what I needed. Thank you very much! 👍
Nice work! Thanks, it helps me. I always turn hemp wrong direction :D
very good. im a master plumber in teas and just finish a big job in isreal. they do it almost the same but put the hemp on first and then tephlon tap after because some valves there cannot work if any pipe dope enters the valve
You're can booger up the threads a bit too it will help keep the flax from getting pushed out of the joint when tightening.
Some fittings have threads that snag the flax so it get pulled into the joint better.
Thanks. Very informative.

Great video, just what I wanted to know 👌
Brilliant video. Thank you - this really helped me.
Excellent video 👍

For thermal installation-radiator pipe with Hemp or teflon tape?
A plumber told me he knows if a DIY'er did a job like this because they used thread tape and not hemp and they have leaking joints. He explained that the water actually swells the hemp and seals the joint. Thread tape is used on the inside of a female nut connector as well as the hemp on the male threads.
I don't use hemp but I use loctite and doesn't leak. So am I a DIY'er? 😂
does it matter in which direction you lay it around the thread? the pipe goes on clockwise, so should the hemp be laid anti clockwise?
No it should go clockwise as well, and be careful that you end the hemp at the end of the thread, so the joint can catch the hemp as it turns and not leak.
great very helpful much appreciated

Problem with paint is that one day you might need the disassemble the parts and it's going to be much more difficult
Which is the proper protocol when using hemp and paste, to smoke the hemp before or after teh plumbing job?
Can you please show what paste you used? It's exactly what we're looking for but can't find it in local home improvement stores. Thank you
Unipak is tha brand name.
Is that why they call it "pipe dope"?
You forget to mention the direction in which you put the hemp on the tube.
Thanks , bravo

Did mine with petroleum jelly, one day later still no leaks
Plus did not even have to tighten it that much

slap some of that blue leak lock on it and be done with it
what is paste? vaseline?

what paste do you use ?
Unipak
Teflon is toxic C8 PFAS
Hamp and past is moutch better

forty two our threads taper?
Every plumber I've seen scratches threads with hacksaw etc...
soap and hemp way better than anything these marketing animals invent

I'm pulmber my name Shahid
hallo, not downstream , opposite direction!
Ok

If you run out of flax, you can always use Donald Trump's wig.
year 1880 just called saying wants the hemp back.

Im a plumber and this is painful to watch
Shit plumber then. It looks sound
Not perfect... Scratch, wrap the hemp then paste. Dont finish wrapping at the pipes end etc.
Magnus Hammargren and that threaded pipe was a bit loose when he dry screwed it on.
pretty sure that's flax..

Stop. Stop stop
