ptfe

Grrrrrrrrrrrrr

PTFE on a compression fitting? Very wrong. A light smear of LSX. I mean a light smear.

Lsx the cheats method ...jetblue is good enough (and cheaper than lsx)

I have never used ptfe on a new fitting, but sometimes if a old one weeps when I redo it up I put a large smear of paste on it and sorted. But never PTFE.
I go to jobs and see ptfe on them and think why ! The olive seals the joint not ptfe.

90% gas leaks i found are on compression fittings abd yes i do use the other type gas ptfe tape

Tplus2 for me.

Im confused now because this is such a grey area Ill be honest if always used PTFE tape on compression because thats what our lecturer told us at college and ive never had any problems but if I can get away without using it then I will

On which part of the fitting?

PTFE should only need to be used threaded fittings

I always use PTFE on soldered joints - I love the smell of burning rubber

 

[tommyl18]

normally put it over the olive where the olive meets the fitting

where does this ptfe on compression joints nonsense come from? im in my 20th year at work and ive never ever worked with another plumber/gasfitter who's felt the need for it.

This debate pops up every so often, everyone has their own way. Personally I never use any jointing compound or PTFE on new compression joints, never needed it. Never has one leaked and I'll keep it that way too. As do other people I only use PTFE on old knackered bits of pipe or redoing up an old compression which is weeping. Use the thicker Gas PTFE too.

Same here. Majority of my compressions are on old pipe or reusing nuts & olives when changing valves etc
