Product overview

Diffuser O-Ring, -330, for 0.75 HP to 2 HP Pumps, Replacement for Jandy — an aftermarket o-ring dimensioned to drop into Jandy circulation pumps without modification. In service it forms the static seal between two mating components under compression. Replacement is routine: rubber hardens, flattens and cracks with heat, chlorine and UV exposure, and a failed o-ring is the most common source of air leaks and drips. Ours is molded in EPDM rubber.
