Hot Tub & Spa - Hot Tub 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 pipework.
The union fittings make for quicker & easier connection and disconnection of components. They comprise a female socket for glueing your pipe into and a female threaded collar that is screwed (hand tight) with an o-ring on to the pump.
