ptfe tape

[gasbanni]

Is it ok to use ptfe tape on olives when putting rad valves on.
regards max

Yes.

Also wrap about 12 turns of ptfe tape on the thread. Pull tight and keep it neat though, as once you tighten the nuts, the tape may push outwards from the sides and be visible.

Went to a radiator job last week where the gas safe installer had done this, with the ptfe tape clearly visible on the radiator valve joints. looked terrible.

Rubbish !

Did you really go to college?

this was actually a tip given to me by my plumbing tutor. Its never failed.

Absolute Idiocy why do you think there at college and not on the tools

My plumber uses a wrap or two of PTFE on all his compression joint threads. 30+ years experience, plus does teaching. Sounds like Naz may know him

PTFE on the thread will probably cause leaks than fix them! the threaded pats is what mates the cone and the nut. PTFE on the olive is perfectly acceptable. Belt and braces.

I only use jointing compound on olive, never PTFE.

I only use PTFE on radiator valve tail ( the bit that go in radiator ) and on male thread that screw into female thread. Used to have hemp and jointing compound before but it a untidy joint.

On immersion heater, no PTFE, only jointing compound as fibre washer is enough.

What I hate is PTFE on tap connector, difficult to remove it when you want to use fibre washer.

Dan.

my tutors were both ex BG, apprentice boys (well old men now with bad backs) time served
they said PTFE tape on threads was the sign of an amateur

Agreed. Any sign of ptfe on compression joints makes the installer looks like an amateur. Hate to see it.

PTFE on a compression is either a sign of misshapen olive or lack of confidence.
