I have a fancy mixer tap to fit for a friend.
Its 3 connections are all 1/2" BSP parallel female.
Should I use parallel or taper males?

Three? Hot, cold and ...?

The obvious answer of using ordinary tap connectors is presumably not
valid? AFAIK you should never mix parallel and taper threads, so I'd
suggest parallel.

The output -- the mixer doesn't include a spout - that's a separately
fitted item.

No - ordinary taps are male, not female.

OK, thanks.

OIC, it's a valve, rather than a tap :-)

Ah, sorry, I misread you to mean female connector required on pipe end
(with image of a normal tap spigot in mind).

I presume you mean these connections are in the body of the mixer? I have
just bought such a tap but it was provided with extension pipes, with,
presumably, 1/2" BSP parallel threads on the end. As the thread shoulders up
to the (15mm) pipe, there's an O ring. Are you certain there is nothing
missing?

I hate threaded connections.. just done eight in a bathroom.
PTFE tape and matching parallel joints is the correct way, but I never seem
to get the correct amount of tape resulting in a leak or near impossible to
screw up, gas PTFE tape is easier IMO as its thicker.

If the seal is supposed to be made by the threads themselves then they
should be tapered and PTFE or Boss White should be used to seal.
As another poster comments, parallel threads should be accompanied by either
a fibre facing washer or (as in the case of the modern mixer taps) a rubber
"O" ring.

Liquid PTFE is great for this

I've had 100% success.

Looks like loctite thread seal to me.. Not PTFE in any shape or form.

There may be something missing. Apparently it was cheap because
it was the display model with no box (or instructions).

I've bought 3 compression to 1/2" parallel adaptors.

It's probably going to be a while before I fit it though;
friend currently has a tiler tiling the room and he's
positioning every tile individually with a spirit level.
Apart from being rather slow, he's doing an excellent job
though.

Ah. In that case almost certainly. Most taps provide either a female tap
connector or a 15 or 10mm pipe. For a display these would have been chucked
with the box in a corner and lost. With the tap I have the box was halved
diagonally by the packing, one half open with the tap in and the other
covered and the pipes were in the covered bit!

No idea, but it works a treat.

I bought a tub of Boss Supergreen with PTFE.
Not tried it yet.

Whilst I agree that liquid PTFE resin is an excellent aid for making
screwed and compression joints (and IMHO much better than tape), the non
non-sense version comes in a standard small squeeze bottle, which is hard
to use. As the bottle get half empty then extracting a few drops becomes
harder and harder. The loctite product in the red "bellows" tube is a joy
to use and works out cheaper because you can put a controlled amount on
each joint, and because you can use 80%+ of the bottle.

It's OK for sealing compression joints for potable supplies where you
shouldn't use Boss white, and also for sealing annoying waste pipe unions
that persist in leaking despite their washer etc. It's not a lot of use
for thread sealing though.
