Join 3/4 imperial to 22mm copper pipe.

Can I join 3/4 imperial pipe straight into to 22mm tee compression piece fitting simply by useing 3/4 imperial olive?

Finger tight then 1 complete turn with wrench should make secure join yes/no?

tia..

Sir

I have aways succeeded with 22mm end feed solder fittings. You have to be carefull on the 3/4 inch pipe as it needs quite a bit of solder ..

Yes, but about 1/2 to 3/4 turn is normally OK.

Lubricate the fitting, I use a *tiny* bit of Boss White.

Don't use solder fittings, the joint is too weak to survive movement.

I "got away" with a 22mm olive in a compresion fitting after the end fed coupler had pissed water down the back of my neck. It did tighten up more than normal as one would expect.

I've just re-read this. You don't use a standard 3/4" olive (if you could still get them) you get a special 3/4" olive for a 22mm fitting.

Solder has little strength when used as a 'filler'. There are proper end feed couplers available for 3/4 to 22mm. You might have to try a few PMs for them, though.

[Nige]

Quite.

ROFL!
