Hemp and PTFE on iron..

[Jay The Plumber]

just for my own interest this.

I've always jointed screwed iron on heating systems with hemp and paste (boss white, green, jet blue, blah blah) but I worked with a guy recently that was running hemp onto the thread as normal but then adding a couple of wraps of PTFE, no paste.
I've never come across this before, anyone been taught to do it this way ?

yea I use 55 for smaller stuff but I had to go and change a load of leaking fittings that had been done like this and they were 2" so I used hemp and paste.

Pretty sure its good for upto 4" pipe work so maybe it wasnt made in right the 1st time!

Knew a guy who used to put immersion heating elements with a few twists of ptfe and boss white said he never had a problem getting them out next time round....regards Turnpin

I have never come across this before. I don't personally like ptfe and more often then not use hemp and jointing compound as necessary.
