Product overview

This o-ring is a compatible replacement for the Purex (Pentair) original, supplied as the Tank Channel O-Ring for CFW and Nautilus Plus NS Filters, Compatible with Pentair Purex. 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 and dimensionally checked against an OEM sample before tooling is signed off.

This part is cross-referenced to 2 Purex (Pentair) OEM numbers — 071442, O-86 — so buyers working from a number stamped on a failed component can confirm the match before ordering. Supplied factory-direct with a 50 pcs minimum, mixed cartons welcome, and OEM or private-label packaging available on request.
