This pair of 1 1/2" slip x 1 1/2" pump unions comes complete with matching gaskets or o-rings for secure connections on your spa equipment.

Each union connects a 1 1/2" pipe or fitting on the slip side and threads directly onto a 1 1/2" pump wet end on the threaded side. Simply glue the slip end to your 1 1/2" PVC plumbing and screw the threaded end to your pump's wet end fitting.

These unions are designed specifically for hot tub installations where both your plumbing and pump wet end fittings measure 1 1/2". If you have 2" pump threads with 1 1/2" plumbing, you'll need a reducer bushing (1 1/2" to 2") to achieve proper fitment.

This is our second most commonly purchased pump union configuration for spa applications. Note that we also stock 2" x 2" unions (our top seller) and 2" x 2 1/2" unions (third most popular) for different plumbing requirements.

Essential components for connecting your hot tub's circulation system to pump wet end fittings with leak-free performance.
