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. 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.
