Protective caps

Polyethylene caps and plugs that protect male and female BSP threads from knocks and dirt during transport and storage. Available in the most common BSP sizes.

They are also used to close the ports of pumps, valves and cylinders while they are dismantled in the workshop, so that no dirt gets into the circuit. The cap for male threads covers the outside thread; the plug for female threads fits into the inside thread. Choose by the BSP size of the thread.
