12mm-1/2 BSPP straight coupling

Straight push-in coupling for 12 millimeter tube with O-ring.
With PTC connection for 12 mm air tube and 1/2 BSP male thread with O-ring.

The male thread is straight and equipped with a sealing ring.
The housing of the coupling is nickel-plated brass.

You can therefore turn the coupling into a 1/2 BSP inlet and connect a 12 millimeter tube to it.

This coupling can be easily used by pushing the air tube into the end of the coupling until it is firmly in place. The tube can be easily removed by pushing the ring back towards the coupling and pulling the hose out.
