Tap tails, connection advice please.

[crispy_wafer]

slowly getting dizzy from going round the bend... Seem to have an array of fittings except the one i need grrr!  What do i need to attach to a copper pipe to allow this to connect please?  I can solder, but compression, or push would do me equally as well.  Got some lovely Hep20 tails, but the connector doesn’t fit my bath mixer controller.  Thin hep is 10mm and the mixer is 8mm.  Ta.

One of these fits, would that be the right type of fitting to use?

Looks like it, should be parallel thread with flat end to seat on a rubber washer in the hose coupling

Yup.

 

Don't overtighten it though, as the rubber seal will get damaged. Hand tight, then a 1/4 turn or so max is usually suffice.

 

Or:

That’s first job tomorrow sorted out.  Thanks.

Want to replace a through deck shower hose to a longer one, valve body has one of these adapters with it, bought a replacement hose but the 3/8” male wont fit the narrow end of this adapter, the valve outlet is 1/2”.  I guess I’m asking if there is such a thing as a 1/2” to 3/8” adapter, or is there another way?

Almost, but I think the problem I’d then have would be, a shower hose with the 3/8 female connector wont fit through the chrome deck mount, 3/8 male no problems.  This plumbing lark and all these connections, well you need to have a mind of a contortionist.  It’s a Problem solving bonanza.

 

Almost like this company who manufactured this mixer from has some kind of protectionist thing going on, it’s all odd sizes.

 

Firstly, the valve didnt have a backnut (must be lost somewhere), tried 3/4” too small, 1” too big, took it to work so the inspection team could measure it up for me, turns out M30, 1.5 threads, thankfully a chap on the machine shop floor found a large nut and recut the threads for me.

Going to post this as could be helpful to visitors in future.

 

For a Basin I have 10mm Hep20 and the tap tails with 1/2” connector.  Because I’m working upstairs and I cannot be bothered running  down and back up to isolate at the manifold, I feel I could do with some local isolation to the basin to make life a little simpler.  What to do?
