The PVC plug with a 3/8″ female thread is a blanking part intended for closing unused stubs, branches or measuring ports in the pool pipework system.
The PVC material resists chlorinated and salt water as well as standard pool chemicals, so the plug does not corrode or deform during operation.
The standard 3/8″ thread makes it compatible with a wide range of fittings, valves and filter housings from various manufacturers.
It is a small but important part – an incompletely blanked port causes water leaks or the ingress of air into the system, which disrupts the proper functioning of the entire filtration.
