Pentair #2-014 Buna N674 O-Ring

The Pentair #2-014 Buna-N O-Ring (Product #: 192323 / 192323Z) is a factory-original OEM replacement sealing component engineered to establish an absolute, leak-proof mechanical barrier within specific high-performance pool and spa equipment connections. Commonly utilized to seal critical low-tolerance fluid junctions, such as air relief valve stems, internal manifold ports, and pressure gauge fittings on premium Pentair Clean & Clear® Plus cartridge filters, FNS® Plus D.E. filters, and select pool chemical feeders, this specialized small-profile ring sits securely inside a precision-machined plumbing groove. When the mating components are hand-tightened or torqued down, the gasket compresses uniformly to prevent localized pressure-side water weeping and block catastrophic suction-side air induction that would otherwise cause pump cavitation and a loss of system prime under operational pressures up to 50 PSI. Molded from a high-grade nitrile rubber compound featuring a standard 70-durometer hardness rating, this elastomeric seal delivers an ideal balance of structural elasticity, superior ozone resistance, and long-term compression memory, allowing it to withstand continuous exposure to high chlorine concentrations, localized thermal friction, and salt-chlorine generation without dry-rotting, flattening, or tearing. The physical dry weight of this single Pentair #2-014 O-Ring is approximately 0.001 pounds (less than 0.02 ounces, with a nominal inner diameter of 1/2 inch, a cross-section thickness of 1/16 inch, and a packaged shipping weight of roughly 0.01 pounds), providing pool service professionals and DIY homeowners with an essential, low-cost hardware safeguard for flawless water management.
