8mm Connectors?

Post by chrisell » Thu Jan 09, 2020 5:43 pm

Simple question - are there 8mm fittings out there that don't need soldering? I'd prefer pushfit but compression will do, can't find them anywhere local or online. Ideally 8mm to any universal thread - but 8mm to 12 or 14 would work.

A quick job is looking like a nightmare right now - someones gone from 14mm to 8mm underground - well its 14mm in the cellar and reappears three foot later as 8mm- everything is hard copper right to the tap/cistern with no flexibility.

I really don't want to dig holes and chisel 2 foot walls

I don't solder -I can only "hot" plumb with Yorkshire fittings and I'm not in the mood for "learning" by floods at the moment and I know you can't get pre soldered.

It's not difficult - it's just like yorky fittings except you have to add a little bit of solder when it needs it- honest!

Like the man says. Easy peasy.

Give both surfaces a good scour with fine wire wool to remove any tarnish or grease.
Paint with fluxite.
Assemble and heat, keeping the flame moving.
Touch the joint with the solder. When its hot enough the solder will enter and surround the joint.
Remove heat and inspect.

I don't disagree but rubbing the inside of an 8mm joint with wire wool is a bit of a bugger.

These abrasive things you use for cleaning saucepans are perfect:

You cut a little band that you force in the fitting and turn it a few turns... Blow the dust and that's it.
Cheap and available in any supermarket...
That's what I used to use as a builder :lol:

When I renovated my first house, my son (4 yo at that time) commited himself to clean all the joints for me... Very efficient as his fingers were tiny ! Sometimes, he was almost bleeding but was crying if I told him to stop ! I felt so guilty :oops:
