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

As pool tech, I’ve used multiple units over several yearsSome 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

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

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

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.

works great for item you have to service

Works like it should for our salt water tank. Easy to install

Overall it is very good quality product. Just one recommendation to the manufacturer, add reducers to 1 1/2” to make it really universal joints.

We've been using these for years. They work great and hold up long time. Haven't had any fail over several years. No leaks. If you have a pool, it's not a matter of if your pump breaks. It's a matter of when. And after you start repairing your pool pump the repairs become more frequent. Take the time and make the effort to put these in make servicing anything much faster
