a) a garden hose with a permanently attached 1" screw thread (Magna Hose
from the USA)
b) an outdoor tap 3/4 inch in diameter
How can I connect them? Is there an adapter to either step up or step down
these diameters? If there is, I'd be grateful if you could point me towards
Are these the *actual* diameters, or the notional diameters? For example, a
pipe with a 3/4" BSP thread (British Standard Pipe Thread) on the outside
has an outside diameter of about 1" - and an *inside* diameter of about
If you have quoted the actual diameters, the chances are that the thread on
the tap is 1/2" BSP and the (presumably female?) thread on the hose fitting
is probably 3/4" something or other - most likely an American thread. I
think that American pipe threads are similar to BSP - but probably not
identical. You can certainly get hose adaptors to go from 1/2" BSP to 3/4"
BSP from any good hardware shop or garden centre. The question is whether
the 3/4" end will screw into your American hose. Take the hose along to a
shop and try it!
Not sure if this is an answer to your question Peter but I came across
I was round a friends and noticed a chain of connectors on the outside
time, most of which were leaking when in use. I suggested you could
get a plastic scew=on hoselock adaptor that would get rid of most of
the bits (inc clamp up tap connector hanging off the hose connector
I went out and got the Hoselock bit (yellow with white threaded
insert) , removed the brass bit from the tap (with mole grips because
it had been fitted very tight on without the 'O' ring) and then found
that neither thread fitted the tap (doh).
I just replaced the tap with a new twin valve jobby and now it's all
All the best ..
