Cistern plumbing - help needed with cold feed connector size

[onwards]

Hi
I'm replacing the toilet cistern valve which is well past it use by date with a Torbeck Ecofil bottom entry valve.. The new Torbeck connector is shorter than the original by 5mm so i need to do a small amount of plumbing work to re-connect the cold feed.
The pipe size is 15mm so i thought I could use a flexible connector from the isolating valve to the valve inlet. I've had a look at screwfix but I'm unsure what i need. Would a standard tap connector do it if I connect it to a stub of pipe coming off the isolating valve. Ideally if it should had a nut at either end I could connect direct to the isolator.
Hope this makes sense.

All help appreciated...

This is what needs replacing:

Forget the torbeck. Get the Fluidmaster Pro (with a brass shank.....)

if this is still too short, get a 'tap' extender, basically its a brass M/F 1/2" section that will extend the threaded part of the inlet valve by some 10mm.

I opened the Torbeck and it's partially fitted so I think I'm stuck with it.
The question I'm asking is would a standard tap connector do it or are the sizes wrong...

The thread ought to be the same, 1/2" British Standard Pipe Thread.

I bought a 15mm x 1/2" tap connector from screwfix with built in isolator which done the job..
thanks
