Product overview
Union with O-Ring, 1-1/2-Inch SxMPT, Replacement for Praher — an aftermarket o-ring dimensioned to drop into Praher valve assemblies 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.
