Product overview
O-Ring, Replacement for Waterco O-290 — an aftermarket o-ring dimensioned to drop into Waterco circulation pumps without modification. In service it forms the static seal between two mating components under compression. It is a wear item: 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.

No. POOLPOINT manufactures compatible aftermarket replacement parts. We are not affiliated with, sponsored by or endorsed by Waterco; the brand name and OEM numbers are used to identify fitment only.
