Frequently Bought with this Shaft Seal
Clear RTV Silicone 6558-0 (For gluing shaft seal into the seal plate)
I have two PB4-60 pumps, one older (Model MO?11110205 and a newer one (Model PB080317261) for my saltwater pool. Will this seal fit both models?
Hello, Yes, these seals will fit your booster pump.
Although my pump/motor is 12 years old, it seems that the shaft seal is leaking.
I could barely make out the name of pump, but it looks like it spells Whisper.

(4 out of 5 stars) Polaris Booster pump seal replacement
Reviewed By: ()
I went with the heavy duty seals for the Polaris Booster pump rebuild because I plant to convert my pool back to salt. The seals went in easily after removing the old ones and polishing the shaft.
