Compression fitting on shower inlet

Sponsored Links
PTFE tape is hopeless, the seal is made by the (hopefully, copper ) olive being compressed into the plastic using leverage applied by tightening the nut.

The internal chamfer on the fitting and the external chamfer on the olive should match and push/compress the olive into a 'bite' on the plastic.

This will provide a water-tight seal.

Edit, sorry Herts if I effectively duplicated your post. Having reread my post, I should say the metal to metal contact provides the seal, the biting into the plastic prevents water pressure pushing the fitting off the plastic. all clear now?
 
Thanks folks

I won't use any plumbers tape.

I know the instructions state not to use compounds but I thought plumbers tape was generic for water pipe joints.

Is plumbers tape classed as a compound?

What are the suitable applications for plumbers tape just out of curiosity?
 
In theory, threaded joints only. Twelve or fourteen turns, never ever thirteen...... :rolleyes: and, never try to loosen a threaded joint even a sixteenth f a turn, it will pour out😳

Has been known to be used on wc flush-pipe to cistern joints in extremis.

The shower is installed and working nicely without any leaks.

Many thanks for the informative advice about plumbers tape folks. The compression joint I bought was a snug fit.

Yes, that's got me out of trouble more times than I can remember. Best if you roll the length of tape on your leg. Bit like a Cuban bird, rolling a fat Havana on her dusky thigh.

Except, you're doing it on your Boss White stained work trousers. And yes, those stains are really Boss White!!! :eek: :LOL:

Also for wrapping around a nasty gash (cut not c*nt) if no plasters to hand as it does not stick to the wound, followed by electrical tape :p
