Pentair #2-342 O-Ring Parker For Triton® C-3 Sand Filter

The Pentair #2-342 O-Ring Parker For Triton® C-3 Sand Filter (part number 152509 or 152509Z) is a specialized, heavy-duty elastomeric sealing component engineered specifically for the large-diameter plumbing connections and bulkhead union assemblies of high-capacity Pentair Triton C and Triton C-3 commercial side-mount sand filtration systems. Molded from a premium, high-density synthetic nitrile rubber (Buna-N), this substantial circular gasket conforms to standard AS568 dash-number 342 dimensions, featuring an inner diameter of approximately 3.62 inches and a thick cross-sectional diameter of 3/16 of an inch. Its primary structural role is to seat securely within the machined perimeter channel of the commercial 3-inch upper or lower bulkhead fitting, establishing an absolute airtight and watertight compression boundary when the external piping or flange valve network is bolted down. This industrial-grade formulation ensures the seal can continuously withstand high-velocity commercial water flow and internal system operating hydraulic pressures up to 50 PSI without weeping, pinching, or experiencing structural blowouts under heavy pump vibration. Engineered to maintain its elastic shape memory under heavy mechanical torque, it completely resists degradation from intense outdoor weathering, extreme seasonal thermal shifts, and prolonged contact with harsh pool chemistry like commercial-strength chlorine, bromine, and seasonal acid washes. Due to its wide-diameter, thick-gauge elastomer ring architecture, this individual bulkhead union O-ring carries a net product and shipping weight of approximately 0.08 to 0.12 pounds (about 1.28 to 1.92 ounces).
