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.


Had a recent thread on this. It suggested the end is flat enough not to cut into the rubber unduly without filing it.
If you file the end flat, you would have to be very careful to make sure it is indeed flat (use a powered bench grinder, not a hand file), or risk it failing to seal at all.

There may be a compression to "parallel male bsp" connector that has a flatter end than the compression with olive removed method.

However using the compression without olive method, you can use a service valve as the connector which is very nifty.
