Pentair 3" Flange For Triton® C-3 Sand Filter

The Pentair 3" Flange for Triton® C-3 Sand Filter (part number 154596 or 154596Z) is a heavy-duty, commercial-grade plumbing connection component designed exclusively for the high-volume intake and discharge ports of Pentair Triton C and Triton C-3 side-mount sand filtration systems. Injection-molded from thick-walled, high-impact PVC and reinforced polymer composites, this robust industrial flange matches standard 3-inch pipe specifications and features a multi-bolt hole pattern along its wide outer rim. Its primary structural role is to serve as the high-strength external mechanical junction that bolts a 3-inch multiport valve, slide valve, or commercial manifold piping securely to the filter tank’s bulkhead fittings. When paired with its corresponding gasket and torqued down, it establishes an absolute watertight and airtight pressure boundary capable of handling massive, high-velocity commercial flow rates and containing continuous internal system hydraulic operating pressures up to 50 PSI without weeping, leaking, or flexing. Built to survive the most demanding mechanical environments, it completely resists structural distortion from heavy pump vibrations, thermal expansion, and relentless exposure to commercial-strength sanitizing chemicals like chlorine, bromine, and seasonal acid washes. Due to its thick-walled, wide-diameter solid plastic architecture engineered for high-torque commercial installations, this individual 3-inch flange carries a net product and shipping weight of approximately 1.15 to 1.40 pounds (about 18.4 to 22.4 ounces).
