O-ring, Large, Diverter Valve (Smart Jet Valve)Item #: 34318
This is the large o-ring found on all water diverter valves beginning in 1994 (Smart Jet Valve). Typically, by the time this o-ring needs to be replaced the entire valve needs to be replaced. The valves will warp and/or score with debris over time making the replacement necessary every seven years or so.
