Extending a pipe from a washing/m cutoff valve

Carlow52

Set up is that I need to extend a 1/2 qualplex pipe that is currently terminated with one of those small isolation valves.
It has a Y piece fitted and the hoses from the washing machine are fitted to the Y piece.

There is not enough qualplex showing to allow me cut it and extend it as normal as its inside a kitchen cabinet unit.

I want to insert a Tee piece in the extension
I will replicate the small isolation valve at the new end.

What fitting will allow me start from the small isolation valve
Thanks

Can you not take off the existing valve, and replace with 310 or 318. Presuming its at the very back of the unit, their is probably room to cut a notch out of the unit, as the press has a void at the back behind the press internals. Post a pic of the setup

3/4 (female)to 1/2 (compression) copper to iron straight, there is a number on it but don't ask my what.

A giacomini tail piece with a 1/2 312.
Billy bunting ,you are talking about a 3/4 x 1/2 312 ,I dont think that would seal on the valve.

I think the 312 is a tapered thread, you get a simular fitting with a paralel thread that you can leave the valve washer on.

The fat rad tail pieces fit the valves perfectly.
