OK so I have finally reached the coupling up the basin taps stage.
Sadly* the advance purchase of 15mm cu to 1/2" tap are all* female

Toolstation do* something suitable but delivery only.

I usually use a 15mm compression / compression service valve... take
the nut and olive off the tap end, and screw the flexi tail nut
straight onto the valve. The tap nut should include a rubber seal in

Yes. They do.

So you will get a good seal on the valve.

Also do tapered thread fittings exist anymore?

They do. Sometimes required for gas work, but seldom for water.

I have a set of bath taps* with a single spout outlet. The
connections appear to be parallel thread* female 1/2".

Unusual for a bath tap IME.
Inadequate description. This is a wall mounted bronze? casting for
filling over the bath side.

Ah, the spout is separate from the tap bit...

Something like:

might make it easier...


You can get male 1/2" bps to compression adaptors that also have a
flange. That will allow an O ring to go round the thread and make a
seal against the base of the tap.

Alternatively you could use a taper fitting and PTFE if you preferred.
Or even a parallel one with lots of PTFE:-)

Yup, it will work, but never feels as solid as a taper fitting.

I see Toolstation do them, item 29242. I'll have to do a shopping run to
a plumbers merchant at some time so I'll ask there. Ta!
