Pump Unions

Pump unions are typically made of PVC and make it easier to remove the pump when servicing the hot tub. They connect the pump suction and discharge to the spa's plumbing and heater.

The union fittings make for quicker & easier connection and disconnection of components. They comprise a male threaded part and a female threaded part sealed together (hand tight) with an o-ring.
