Adding isolation valve to tap connector

[Jakg]

I've just bought a new kitchen mixer tap, but I noticed that there's no isolation valve on either hot or cold so I have to turn all the water off to do anything.

The water pipes are copper with a compression-to-screw fitting on the end where the tap tails attch with this connector

I've seen lots of isolation valves online, but they all use compression fittings onto the copper pipe. Is there an isolation valve that connects to the fitting already on the end of the pipe I have, so it can go between the tap tail and the threaded connector?

Why not take the connectors back to where you got them and exchange them for connectors with isolation valves, not a great difference in price normally .

I need 400+mm tails really. I can't find any in that size. But i'm happy to replace the the tails as it means one less joint.

Afaik the standard ISO valve is the same thread as your flexible connector so you just bin one of the nuts from the valve and screw the tail on

If you've already fitted the mixer tap, why bother? For the few times you're likely to want to work on it, I'd have thought it's less hassle to turn the water off than add valves.

Couple of these on the flexible pipes ...

I replaced a mixer tap recently, and the end fitting on the new hose was bigger, 1/2"BSP. OP's pic looks like 1/2", I assume that's the standard these days. The original was most likely 3/8". I thought no problem, I'll re-use the old flexies, but the thread at the tap end was different as well. Had to buy new fittings.
As an aside, modern 15mm compression fittings use 1/2"BSP threads, but I have some old ones with finer thread. Obviously as you have both parts it doesn't matter. I also have 22mm compression fittings with different threads. Neither is 3/4"BSP as there is insufficient wall thickness for 3/4"BSP thread when 22mm is subtracted from the OD of a 3/4"NB pipe.
