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.

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 You're right. Seems to be a ******* 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. -- Dave Baker

I have the same problem, but it's at an allotment site where I don't own the 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 3/4 Hozelock one that I told them was TOO SMALL?
