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.

What equipment does O-290 fit?
It fits Hydrostorm. Those are equipment models, not part numbers — order against O-290 itself.
Is O-290 a genuine Waterco part?
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.
What is the minimum order quantity for O-290?
MOQ is 50 pcs per part, and mixed cartons are welcome to reach the order minimum. Samples are a separate case — we supply single pieces so you can confirm fitment before committing to a production run.
What material is O-290 made from?
O-290 is produced in EPDM rubber, dimensionally checked against an OEM sample before tooling is signed off.
