Imperfection pipe works call for PTFE.

[John_]

a plumber mate of mine said only imperfection pipe works require ptfe or compound. As long as pipe works are perfectly straight, olive is sufficient. PTFE and compound are to hide flaws. Is he right?

This has been covered many times. It's purely a case of personal preference whether PTFE or a sealing compound is used or nothing at all.

I don't put anything on new Kuterlite fittings, but tape up cheap imports or old compressed pipe.

Agree with system3 covered many times,

I always use PTFE.

depends what mood i'm in really, mostly nothing, sometimes some paste

 

[glenno1]

So not even on rad tails

 

[GQuigley67]

thought we were talking about compression fittings

threads is a whole different story, usually around 20 wraps of ptfe

Sorry thought op meant on plumbing as a whole,i read post wrong duh

On parallel threads, yes you'll need something. But on new compressions, not unless there's something wrong with it.

I never use ptfe or compound on olives, until they leak

I think I have a ptfe fettish,

I carry 3 rolls in by tool bag 10 spare on the van and a couple in my pockets,

If I get down and dirty with my girlfriend then there is a roll of PTFE on the side just to fill gaps if needed..................
