BadAss Pool Supply O-Ring Rebuild Repair Kit for Pentair WhisperFlo/IntelliFlo, Black Gasket, for Pumps Built 2-1-2008 and Later. This Includes The #1 Choice of Shaft Seals from US Seal Mfg.

Bought this for a leaking pool pump. I have learned that preparing pool equipment is a LOT MORE cost effective if you can manage it. It is not rocket science but it does require some care. The kit arrived with all the seals that appear to be of premium quality. The ceramic seal included is the premium quality recommended US Seal PS1000. The pump had been leaking from this seal and so special care was used in the reinstallation of the new seal. The one part is carefully drifted into place in the flange (using a wrench socket as a drift).The second part is pressed into the impeller using a tiny smear of RTV around the rubber perimeter. VITALLY important not to touch the ceramic surfaces, in fact a cleaning with isopropyl alcohol is good insurance here. Taking special care to clean, descale, wash and dry all the parts, the pump flange was easy to reassemble. It is important to take care to tighten all the bolts evenly and in rotation up to the recommended torque value. All the seals and rings fit perfectly and the included instructions were valuable. A few weeks on all is watertight and working perfectly. I would highly recommend this kit - good price and fast delivery.

Kit is exactly what I needed at less than half from oem supplier. Quality of parts is good easy to installation is not to hard if you watch online videos for it.

Worked as expected. Saved a lot of money rebuilding the old pump.

Kit should include small, specialized lubricant required for seal/shaft. Seal Mfg. instructions state do not use the in-kit silicone-based lubricant which is intended for rubber gaskets only.

Had to replace impeller on Pentair VST pump due to impeller shaft seal seal failure. This kit replaced all the seals needed for reassembly. All fit well and pump running daily for past month with no leaks.

I am very good at DIY but this one was challenging due to the fact that every bolt and screw was corroded. It required a high-torque impact driver to break the bottom 2 bolts loose and I had to remove the plastic fan cover to hold the shaft when removing the impala. The kit worked perfectly once I got past all the stuck bolts. The pump runs great now and no more leaks.

This is a perfect fit for our pump. I was expecting things to not fit quite right, so I was surprised when each O-ring slipped into place. I've been using it for several months and no leaks or problems.

Good kit to rebuild the seals in Pentair IntelliFlo 350305S . I waited too long to do it and had other problems. Looking back, I should have done this proactively or at the first sign of a tiny drip.
