Thinking bigger is better I bought the 3/4 inch outside tap from
Toolstation. Item 32002. The 3/4 refers to the bsp thread size
conecting to the backplate.

I want to use hozelock type fittings but cannot work out how to connect
to the outlet which has a male thread.
A 3/4 inch hozelock connector is too small
A 1 inch hozelock conector is too big
It does not appear to be a bsp thread as the pitch is too fine.

Is there a standard for these tap threads I should know?

In article <MPG.2e597a6bd...@news.eternal-september.org>,
Outside taps with threaded spouts are usually 3/4" BSP (same as
appliance hose connectors).

I've never come across a tap that wasn't BSP. 14TPI.

I have, very rarely, come across 7/8" BSP tap threads. Tap connectors
do exist GIYF.

oh yeas, there is a standard... just every country/region has a different
standard,

i amassed about 20 different adapters and fittings for taps when i had my
motorhome, to enable me to fill up with water from almost any tap in europe,
and i still got caught out in scotland with a tap thread inbetween the
standard 3/4 and 1 inch bsp threads (used for half inch and 3/4 inch hose
respectively)

it could be that which you have now? unfortunately i dont know the thread
as i just used a universal cuff type adaptor (the ones with a jubilee clip
to hold the rubber cuff on any tap)

Only in the 1/2" to 7/8" range. For 1" and above, it is 11TPI.

I wonder if it is US garden hose size?

I would expect it to apply to the outlet connector too. There would be
little point in having a different connection there. Have you tried
screwing it into the backplate to check?

.... which, I can confirm, is a bitch to try and match in the UK. I
ended up with a jubilee clip type, as mentioned earlier.
Somewhere out there, I am sure, is a neat solution.

I recently bought a new Hozelock tap connector which had an insert that allowed it to be screwed onto a smaller tap outlet, maybe that is what you need? As my tap has the standard thread it was not needed, unfortunetly I threw it away otherwise you would have been welcome to it.

The outlet is definitely bigger than 3/4" bsp and smaller than 1" bsp.
I do not believe it is a bsp thread as it is much finer - a pitch of
about 1mm rather than 2mm.
The OD of the male thread is 30.2mm
The ID of the female thread for the 3/4" hose connector fitting that
came with it is 28.5mm

Thanks, but the Hozelock one I also had isn't the right size for a US
thread. The clamp type one I have does fine until such time, if ever, I
find the right fitting.

I can't find anything in my thread tables that match all those. The
diameters are right for 7/8" BSP, but that should have a 1.8mm pitch.
Nothing else comes close.

That should be just under 30mm OD. 30.2mm OD is spot on for 7/8" BSP.

Toolstation did not know, but the supplier to Toolstation is Mueller
Primaflow who said it is a G 7/8 thread, which I undersatand to mean a
BSP thread. Looks like I cannot estimate thread pitch. I'll see if I
can find something to fit.

I am going to try G7/8 to Geka then Geka to Hozelock.
Simpler to have bought the smaller tap!

Yes it should, but I have ordered the other stuff now.
My local supplier only has the Gardena 1" and 3/4" flavours in stock.
Did not realise the 7/8" version was made by them.

A bit grumpy now.
Having been told by the supplier it was a G7/8" thread, I ordered the
necessary parts and received them in the post today. However the G7/8
connection does not fit. It is the correct diameter and the thread
engages, turns a few degrees and locks up. As I first thought a few
days ago, the thread on the tap outlet is a finer pitch than the
standard BSP threads.
So not sure what to try next.

Cut to the chase and get the smaller tap you should have got in the first
place.

+1 That is not any standard thread that I can identify. The only thread
I can find with a 30.2mm OD is 7/8 BSP and that is 14TPI.

Ask Toolstation to stock the connector.
