Pentair Boost Rite O-Ring Kit, ZBR12200

The Pentair ZBR12200 is the o-ring kit for the Boost-Rite universal booster pump, supplied as a two piece kit of genuine Pentair seals.

Where these go

A booster pump is the small pump that supplies pressure to a pressure side cleaner, and like any pump it seals at the joints with o-rings. Those seals live hot and wet, take a set against the housing and then leak once the pump has been opened. If the pump has been dripping, or if it is coming apart for a motor or seal job, this is the kit that goes back in with it.

Fitting

Wipe the grooves clean before the new o-rings go in, and use a silicone lubricant intended for pool and spa work rather than a petroleum grease, which can swell rubber. Lubed seals seat without rolling and lift out cleanly at the next service.
