Compression fittings.

Just back from a job, leak on a compression fitting; some tw.t had used PTFE instead of Boss White on the olive??!!!

 

[footprints]

I remember when I started as an apprentice we got to a job and the boss white tin had got lost on the way (fallen off the back of a bike!) so the fitter used flux to make the threaded joints on a gas supply! I often wonder how well it held up

Is this a joke thread? Why should we put Boss White (or PTFE) on an olive? Doesn't the olive create the seal?

Nobody uses Boss White any more Puller, it's not WRAS approved

One that uses decent copper olives and doesn't overtighten everything.

Will get a leak, as it's a metal to metal joint & needs joint paste.
A little mechanical movement will also result in a leak - copper or brass olive.

I disagree but this argument has been done to death, and you're ***********

Yorkshire kuterlite say use a light oil on the threads and ptfe sealant if necessary with R250 tube and recommends using ptfe sealants with steel and stainless tube with tape as an alternative.
I use Jet lube V2 plus which is WRAS approved for potable/non potable , is a soft setting, non-petroleum based thread sealant for use on metal, plastic (non-ABS), threaded connections for water, bottled and mains gas, compressed air, oils, fuels, refrigerants and most other liquid and gaseous chemicals.
