I want to buy a hose pipe to attach to the outdoor tap at my new house. Thread size measures up at about 30mm o/d and a tad less than 2mm pitch which doesn't seem to be any normal BSP size. Is this a standard metric thread for garden taps?
In the sheds what you can buy will fit... I thought they where 3/4" BSP but thinking about it that is the same a washing machine conector which is smaller, so 1" BSP.
Wikipedia has 1" BSP as 11 threads/inch 1.309 inches dia (2.309 and
33.249 mm). Have you measured yours or just eyeballed it?
Knowing the OP reputation as a precision engineer, I'd assumed his measurements to be reasonably accurate. About 30mm o/d and less than 2mm pitch stacks up with 7/8" BSP x 14tpi. Bob
IN 30+ years of selling pressure washers I've never come across one that didn't have a 3/4" bsp male thread for the inlet connection. The Hozelock tap connectors fit them & the tap.
in my travels around europe in a motorhome, i came across loads of different tap connections,
in france it seem'd popular to have 2 taps side by side fed from a large bore pipe, one would be the standard 3/4 fitting for 1/2 inch hosepipe, the other would be the next size up, used with 3/4 inch hosepipe,
difference in flow was fantastic, could fill the 150 litre tank up in about half the time with a 3/4 inch length of hose,
I collected a load of adaptors over time, so i could connect to almost any tap i found, the one that got me was in scotland, service station in aviemore, sized slightly larger than 3/4, but smaller than any of the larger adaptors i had, used the back up of the rubber cuf and jubilee clip to connect to it in the end.
You're right. Seems to be a bastard size which no one stocks anything for. Might be easier to change the whole damn tap than try and connect a hose to it. Arse.

I have the same problem, but it's at an allotment site where I don't own th e tap, I just want to attach my hose to it. Did you ever find a solution?
Hozelock recommended I buy their 5/8" attachment - I think in metric so it took me a few beats to work this one out - hey, isn't 5/8 smaller than the

Yes, if indeed what you had was 3/4" BSP. But bear in mind that the
*actual* size of 3/4 BSP is 1.041" (about 26.5mm). If the *actual* size of the fitting you had was about 3/4" in diameter, could it have been
1/2" BSP - whose size is 0.825" (just under 21mm)?
