Good quality O-ring replacement kit
Replacement for an outdated O-ring for Pentair Whisperflo/Intelliflo Pool pump. Fit's perfectly fine and was able to reseal the pump. Comes with sealant in a small bag.

Fit my Whisperflo pump perfectly
Sealed everything up great. You'll need a 32mm socket and a hammer to press in the new seal and a smaller socket (maybe 15mm or so) to hammer out the old one. The impeller can be removed from the motor axle by unscrewing it in a standard fashion while holding the motor axle still (lefty loosy). However, the impeller set screw is reverse threaded. Everything else in this rebuild project is pretty intuitive

shaft seal doesn't fit OEM impeller
The opening in the base of the black rubber seal around the ceramic ring is 4mm too small to seat properly in the OEM impeller (Pentair IntelliFlo VSF 3.0HP, mfg 2019). I had to purchase the 356198 Pentair Pump Seal Quick Kit for the properly sized shaft seal.
