Swimables 2" Hi-Temp Union Compatible with All Pentair Whisperflo and Intelliflo Pumps for Inground Swimming Pool 21063-200-000-2" MIP x 2" Slip PVC - Made in USA - 2 Pack

So much cheaper price than pool supply store

As pool tech, I’ve used multiple units over several years Some observations . . . 1) threads on adapter into pump are clean , sturdy and precise. 2) screws into pump with tight, complete fit. 3) the o-ring that seats against pump is what seals airtight, not the threaded portion. 4) therefore, I add generous amount of silicone lube to threads and oring. 5) one slight difficulty - the new union is hard to unscrew. Hence, I add silicone lube to the union threads also. Problem solved. 6) one caveat, installing just one union on pump can be difficult to impossible. Installing on both inlet and outlet is . . . easy. 7) I’ve had some installed for several years. No problems. Recommended

I have bought 2 sets of these. They install super easy and do not leak at all.

Seems good quality. Does not fit Superflo pump as stated as compatible in the picture description. The internal superflo threads turned out to be smaller than whisperflo.

Work great for washing machine drain to put 2" drain instead of that little one

Bought these for our pool filtration system for ease of maintenance. They have proven to fit well and are good quality, durable and leak free. Good product

Great solution where you want to have 2 unions close to each other. The long neck allows the close placement without interfering with the other union.

We had to replace the original fitting due to the old fitting wasn't sealing tight. These fittings were installed on pool pump which were far better than the original fittings

Parfait
