Anyone wrap olives in ptfe ?

No, it shouts of amateur.

Oddly, it was a pro I got the tip from. Long before newsnet.


I prefer to use any other lubricant if it is
necessary. Petroleum jelly if potable.

It's not acting as a lubricant. More of a sealer.

You've contradicted this statement below?

PTFE should be confined to threads IMHO.

The threads pay no part in sealing a compression fitting.

I meant threaded fittings and not compression fittings, such as taper
threads etc.

The question was about PTFE on an olive? Using it there helps the seal
between the ends of the threaded part that the olive bears on. It might
reduce friction too - but then I always tighten compression fittings till
they groan. ;-)

One of the times that ptfe on the thread of a compression fitting helps
- you are able to work much quieter without all the squeaking and
groaning :-)

(also good for restricted spaces which need short spanners, you can get
better tightening)
