Pentair .157" x 5.75" Triton® II O-Ring Valve Body

The Pentair .157" x 5.75" Triton® II O-Ring Valve Body (part number 154493) is a precision-engineered sealing component manufactured specifically for Pentair Triton II side-mount sand filters and Tagelus top-mount sand filtration systems utilizing 1.5-inch HiFlow multiport control valves. Molded from a high-grade, chemical-resistant synthetic rubber compound, this circular gasket features a specialized cross-sectional thickness of 0.157 inches and a wide 5.75-inch nominal circumference. Its critical structural role is to sit inside the machined channel of the main valve body interface, providing an absolute airtight and watertight compression seal against the filter shell under high hydraulic flow. Built to maintain its shape and elastic properties despite continuous exposure to high system pressures, corrosive pool sanitizers like chlorine, and fluctuating water temperatures, it actively prevents dangerous external leaks. Because it is a streamlined, lightweight rubber component, this individual sealing ring has a minimal net product and shipping weight of approximately 0.05 pounds (less than an ounce), serving as a crucial yet easily replaceable part for maintaining filter system pressure integrity.
