Product overview
This o-ring is a compatible replacement for the SuperPro original, supplied as the Tank O-Ring for FNS Filter. 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.

What equipment does O-420-9 fit?
