Bought a pressure gauge for testing water pressure inside the house (water hammer when turning off mixers, etc.).
It is marked as 1/8" BSP - looked up and it seems actual diameter is 9mm (I measured around 10 using caliper), I am not sure what kind of adaptor to get from bunnings to make it a screw on device for outdoor tap for garden hose, or to connect to wash basin mixer wall outlet, etc.
Thanks in advance.
