Great
Worked for my application. Fits my hot tub pump motor, got two oring gaskets, and fit 2 inch pvc tubing. Can’t complain. Would order again for my secondary pump in the future

Perfect match to the old ones we replaced.
Worked great for our koi pond filter. Old ones were getting brittle.

DID NOT fit my B&D 1.5" variable speed pump
Someone posted it fit there B&D pump so I took a chance cause, as they posted I did not want to pay 50 through B&D. It fits using the male pentair adaptor but the male threads / ID is considerably smaller than a 1 1/2" MIP to pvc internal diameter. Just posting beware, does not fit my B&D pump.

Missing O-ring
O-ring missing from unit. Other than that, great.

Works great!
A hot tub vendor quoted me a hilarious price saying these parts are specific to the model and no longer made. Turns out that was wrong. Worked great!

Works but not perfect
So, this is indeed a pump union and fits my T15 salt cell. Trouble is that the o-ring supplied is just slightly too large for the groove it's suppose to fit into which means it does not stay put across the entire circumference and you have to be extra diligent when screwing the coupling in place. This was true on both parts I ordered.

Perfect fit to my Black & Decker 2HP Variable Speed Pump.
This replaced my Black & Decker 2HP Variable Speed Pump 2" intake union. The B&D 2" union kit is $65 with shipping so this was a huge savings and came next day instead of 5-8 biz days. Installation to my 2" suction line plumbing was complete myself and I have no issues. It's a perfect fit.

Doesn’t last long
Bought for our hot tub. Only lasted 2 months before it cracked.
