Compression fittings

[evans1]

I am about to fit a new shower that connects to the mains water via a 15mm compression fitting. The old shower had a screw thread so i have had to buy a new fitting. The query i have is that the new shower connection is not threaded but smooth with nothing for the compression to screw onto, is it called a compression because it compresses and does not actually screw onto its connection but just tightens ? . However the compression fitting does tighten on the new showers smooth connector...I went into my local Focus DIY with the showers book and none of them were to sure (shock).

Cheers

What does the instruction say.

It says word for word the following.


the inlet fitting is designed to enter a compression fitting only. DO NOT use push fit connectors as full engagement cannot be guarenteed. DO NOT use excessive force when making these connections..

Thanks for the link I think I know what a compression fitting is

Buy a compression straight or bent connector and fit it over the spigot and do the nut up.

I noticed that "the natural handyman" advises against using metal olives (compression rings) when using comp. fittings with plastic pipe. He says use plastic olives (which don't exist here in UK as far as I know). I know the site is US based, but does anyone think he has a point?

them cheap plastic valves that come with the cisterns have plastic O rings

Doitall, shouldn't you change your name to knowitall?

Does the US handyman have a point.... well their tiles fall off and their O rings fail...and that`s just NASA

Na unless you intend to launch your shower into space I should'nt worry about it

Just been over to TT (desperate I know, but what else should plumbers do on Sunday afternoons?) and noticed that the "knowitall" gag's been done! Probably years ago! Oh well, I'm a bit new to this posting lark, so thanks for not mentioning how slow on the uptake I was.
