Filter mount 1.5" MPT

This threaded mounting point fits into the shell of your spa, and allows you to screw in any filter cartridge with a 1.5-inch MPT thread, like a MAX50P4, for example. You can often find this part in spas where the skimmer compartment is moulded directly into the acrylic shell. It connects to 1,5-inch pipe with a female fitting.

This part is delivered with a nut to hold it in place, and a flat gasket.
