TonGass (2-Pack) 2" MIP x 2" PVC Hi-Temp Unions, Compatible with Pentair Whisperflo & Intelliflo Pool Pumps - Hand-Tightened Pool Pump High Temp Unions - Replacement for Schedule 40 Male Adapters

Good quality and works very well

Don't buy these - female slip joint side was too large for standard 2” schedule 40 pipe. Not sure how they can be advertised to fit when they clkearly don't. Totally unusable but of course the return process with Amazon was easy as one click - so thank you Amazon for that

When my pool pump was installed they used the regular 2" home depot fitting which worked great for many years. Until an air leak on the suction side of the pump caused my pump to cavititate when it came on one morning. My pump was running dry for several hours before I noticed it. After replacing the pump filter basket cover O-ring everything worked fine. That's when I noticed the fitting on the outlet of mu pump started leaking from the threads. I never thought my pump would get hot enough to deform the threads on a 2" fitting. So I searched Amazon for Q.D. fittings and came across these QD fittings. Being that I have a Hayward pump I wasn't sure they would fit but since my pump threaded connection are 2" figured they would and they did. These Q.D. fitting are high quality and work perfectly. They also come with 2 spare O-Rings. I am very satisfied with them. You get 2 couplings for the price Home Depot sells just one and these coupling can with stand high temperature in case my pump cavitates again. I highly recommend them.

Made my job of installing a new pool filter so much easier! Couldn’t have found a better product.

I read all the reviews and as long as you have schedule 40 PVC these will fit. They are very snug and not loose at all. I don't know what kind of pipe people were using who said that they didn't fit.
