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 allÂ* female fittings
where the poxy flexible tails need male couplers. I think Toolstation do
something suitable but delivery only.

Also do tapered thread fittings exist anymore? I have a set of bath taps
with a single spout outlet. The connections appear to be parallel thread
female 1/2".

Taps use a parallel thread with a fibre washer to seal - don't over
tighten. The washer will swell when wet and improve the seal. I usually
do "finger tight" then a bit with a spanner.
