Pentair Plastic Clamp with Screw and Nut

The Pentair Plastic Clamp with Screw and Nut (part number 192323 or 192323Z) is a specialized, light-duty external retention band assembly engineered to secure the manual air relief valve, pressure gauge, or dome closure adapters onto the top ports of Pentair Clean & Clear, Clean & Clear Plus, Predator, and FNS Plus pool and spa filtration systems. Injection-molded from a thick, high-impact, and UV-stabilized polymer composite, this interlocking split-ring clamp is bundled with a high-tensile steel screw and a matching hex nut. Its primary structural role is to wrap completely around the flange interface of the tank's top adapter fitting, acting as the primary mechanical lock that pinches the internal sealing O-rings tight when the screw is torqued down. This localized, high-compression boundary allows the air relief assembly to safely contain continuous hydraulic operating pressures up to 50 PSI without weeping, leaking, or experiencing dangerous component blowout under pump vibration surges. Built to endure relentless outdoor UV weathering, intense seasonal temperature shifts, and prolonged contact with harsh pool chemistry like chlorine, bromine, and acid washes, this robust plastic clamp resists cracking and structural fatigue over years of heavy use. Due to its dense, semi-circular plastic halves and small metal hardware pack, this individual clamp assembly carries a net product and shipping weight of approximately 0.15 to 0.25 pounds (about 2.4 to 4.0 ounces).
