When should you not use PTFE tape?
An important thing to remember is that PTFE tape should not be used when connecting PVC fittings or valves with a female (FPT) thread. If the tape is used on female connections, a wedging action can occur which will cause major stress on the joint during assembly. PTFE tape does not guarantee a leak free connection.

Can PTFE be used on compression fittings?
Here is what Martin an emergency plumber has to say “the amount of leaks I have found in the past maybe because the local builder, kitchen fitter or any other type of DIY plumber has decided to do it themself to save money rather than call a local plumber. It is not a surprise to find that more than 50% of DIY plumbers will use PTFE on a compression fitting which is a reason that a DIY plumber in most case should not be trusted” in the next paragraph it will explain how PTFE should be used with compression fittings.
Why should you not use PTFE?
1) The seal is created by the olive crushing into the pipe and the olive against the joint - not the threads. 2) Using PTFE can clog the threads and thereby prevent the threads doing their job which is to compress the olive against the joint.

What does the thread on the end of a fitting do?
The threads on end of fittings where the pipe goes in is only for the nut to pull the fitting and pipe with olive together. If a joint was to leak, the ptfe on the thread at pipe end wouldn’t seal the joint anyhow, as the water would simply go between the nut and the pipe.

What is the best sealant for a compressed olive joint?
Ptfe tape wrapped around an already compressed olive will help seal the joint, but paste is better and essential to prevent small leaks. Microscopic leaks occur if the joints aren’t pasted and the seized nuts or white corrosion on the brass threads is proof of this. V2 Lube is good and does potable water.
