It's quite common for imported taps to have tails terminated with a 3/8"
BSP nut incorporating a rubber sealing washer.

The simplest way to connect to these with standard parts is to get hold
of a 15mm to 12mm (or 15 to 10) straight compression reducer. Discard
the nut and olive from the smaller end and file the end flat so that the
chamfer does not cut into the rubber washer. Connect the other end to
the 15mm pipe as normal.

Hope this helps,

Roger.
