I have some 3/4" brass bibcocks on the way to me - these are the bigger
version for a stand pipe (the more usual 1/2" ones are 1/2" BSP input and
3/4" BSP where the water comes out)

Try as I may I cannot find the thread specification for the output side of
these bigger taps. Not yet to hand but I'd guess at 1" BSP logically

I want to get male Hozelock Q/D fittings onto the taps but bigger ones are
proving elusive. If anyone has any insight it would be appreciated if you
could share it!

Cheers,

Andrew

You need to measure threads and compare with sizes he
https://en.wikipedia.org/wiki/British_Standard_Pipe

A 3/4" BSP fitting has a thread 1"

For an example of a reducer 1/2"M x 3/4"F:

I would hope you can get one locally, or with a better price on postage!

When they arrive I have absolutely no problem measuring them but they
haven't arrived !!!!!

Ah yes, that might help.

Can you supply a manufacturer's part number?

I'm pretty sure the tap will be 3/4" BSP.

If you want to match this to Hoselock items:

I've met 7/8" - but I've led a sheltered life as an office wallah so
that counts for little. I certainly don't suggest it is a (let alone
_the_) standard.

I think reducers to 3/4" can be bought - or contrived by cunning
artificers

Still not got them but I'm pretty sure that they are indeed 1" BSP on the
outflow side - sufficiently convince to buy the Hozelock male fitting for 1"
BSP which is significantly more expensive that the 1/2 and 3/4 sizes:

very probably given my history for being wrong

That's about half what my brother tells me the 7/8" equivalent cost his
allotment club - albeit they bought locally. (That also reminded made
belatedly that 1" BSP is 11 tpi while 3/4 and 7/8" are 14 which might
have helped if you'd a photo of the tap.)
