15mm Compression x 1/2" BSP Radiator Valve Tail

This radiator valve tail connects a radiator to a standard radiator valve.

The tail has a compression nut and olive (included) to suit a valve with a 15mm compression type outlet (common size for TRV).

The male thread is 1/2 inch BSP (normal size for the connections on a radiator).

Does not suit a union type radiator valve with a bigger 3/4 inch BSP outlet.

** BSP thread sizes are measured a special way - have a look at our information page for more details **
