Stainless steel pipe & Compression fittings

[skenk]

When doing brass compression fittings on stainless steel pipe is there anything you do different from copper? All the existing joints have ptfe on them which would seem to make sense as SS is a harder pipe?

a little lick of boss white always helps

I have found that it also helps to clean the SS of back to copper and then fit the compression fitting however i only do this due to an accident with pushfit and SS

are you referring to chrome plated copper tube here, and not stainless steel?

With that in mind, I'm curious about where the op is using stainless steel pipes and compression fittings.

Cant use boss white as it's cold mains. Changing from communal loft tank to mains feed for bathroom. Done a few with ptfe and they seem fine. Should I be fitting flow restrictor(s)? Pressure is v-high.

The tenement was totally renovated by the local authority in 1978 been told SS was used to to deter theft!

you can use boss white, you just dont tell anybody

if you are going to be pedantic then you shouldnt be using ptfe (its a wee bit amateur)

as per your boss white semantics, consult the regs concerning pressure reducing sets

use boss green, for potable water supplies. SS is also a good deterent to stop galvanic reation taking place between dissimilar metals.

You need a Brave Heart and Balls of ( stainless) Steel to go round breaking rules in that Cavalier fashion
