Pentair 2" MultiPort Valve Diverter Gasket

Pentair 2" Multiport Valve Diverter Spider Gasket (271148 / 271104)

The Pentair 2-inch Multiport Valve Diverter Spider Gasket (Product #: 271148 / 271104) is a critical, factory-original OEM sealing component engineered specifically to manage internal fluid separation within Pentair and PacFab 2-inch Hi-Flow™ side-mount and top-mount multiport backwash valves. Designed with a custom-molded, spoke-like web structure that nests flush inside the lower grooves of the valve body, this heavy-duty gasket creates an absolute hydraulic barrier between the isolated internal chambers. When the valve's upper handle is depressed and turned, the internal diverter presses firmly down onto this rubber matrix, allowing pool water to be routed to its designated cycle—such as Filter, Backwash, Rinse, or Waste—without any internal fluid bypass. Molded from a high-density, premium neoprene rubber compound, it delivers superior structural elasticity, ozone resistance, and compression memory, allowing it to withstand high chemical concentrations, mineral scaling, and heavy hydraulic friction without distorting or tearing. Swapping out a worn or stretched spider gasket is a vital maintenance step that instantly cures common system issues like water continuously weeping out of the pool's backwash waste line or unfiltered water bypassing the filter media and flowing back into the pool. Built to withstand extreme pump room heat and operational line pressures up to 50 PSI, this component ensures your filtration pad runs at peak hydraulic efficiency. The physical dry weight of this Pentair 2-inch multiport valve spider gasket is approximately 0.12 pounds (roughly 1.92 ounces, with a nominal shipping weight of about 0.20 pounds and a total outer diameter of approximately 5.6 inches), offering pool professionals and residential managers a lightweight, robust, and indispensable hardware solution for flawless water management.
