A relative has an outside tap - about 25 years old. A modern hoselock
fitting is too big for it - and the supplied reducing bush is too small.

The standard hozelock is 3/4" bsp and the adaptor is 1/2" bsp. Given the
age of the tap and that it seems between the two, it could be 5/8" bsp
although I've never come across one - ever. I doubt you will find one
either.

Take a look at http://tinyurl.com/a92q9 this may be your only option - or
change the tap - not difficult.
