I've got new 3/4 inch taps, but the Quick Release 3/4 Inch Garden Tap Connectors for my garden hose don't fit as they are too small and the inch versions are too big. Any ideas?

Answer

Normally the alternative to 3/4 inch BSP threads is either 1/2 inch, 5/8 inch or 1 inch. If you measure the threads they won't actually be this size because the thread size historically refers to the internal diameter of a thick walled iron pipe used with the fitting.

Have a look at the table at this link which gives the sizes of various type BSP threads. You should be able to identify the thread by both the number of threads per inch and diameter.
