Compression Couple Male C X Mi - 10Mm X 1/4'

Compression Couple Male C X Mi - 10Mm X 1/4'

The 10mm x 1/4" Compression Male Straight Coupler is a specialized transition fitting used to connect 10mm OD (Outer Diameter) copper or plastic pipe to a 1/4" BSP (British Standard Pipe) female threaded port. This fitting is essential for connecting small-bore pipework to valves, manifolds, or specialized appliances.

Because it uses a mechanical compression joint on the pipe side, it requires no heat or solder, making it ideal for repairs in tight spaces or for use with plastic pipework (when used with the correct insert). The male threaded side (MI) typically requires a thread sealant or a bonded washer to ensure a pressure-tight connection.
