Pentair 1.5" HiFlow Diverter with O-Ring

The Pentair 1.5-inch Hi-Flow™ Multiport Valve Diverter with O-Ring (Product #: 272512) is a factory-original OEM replacement fluid-routing rotor assembly designed to restore internal sealing integrity and positive mode selection to pool and spa filtration setups. Engineered as a direct drop-in core for Pentair and PacFab 1.5-inch top-mount and side-mount six-position multiport backwash valves, this component is highly compatible with residential Sand Dollar® and Tagelus® sand filter lines. Injection-molded from a premium, thick-walled Noryl® engineering thermoplastic, the massive diverter wheel features a highly structured, molded segment configuration that aligns perfectly with the lower valve body chambers to execute vital water cycles such as Filter, Backwash, Rinse, Waste, Closed, and Recirculate. This replacement part arrives pre-assembled with a heavy-duty, high-density rubber shaft o-ring seated onto its central vertical stem, which forms a dynamic hydraulic seal against the valve cover to prevent pressurized water from weeping out of the top handle. When the valve lever is operated, the flat lower face of this rotor compresses tightly against the valve body's spider gasket, isolating fluid paths to completely eliminate common system failures such as filtered water leaking out of the backwash waste line or unfiltered debris bypassing the tank media. Built to take the brunt of continuous rotational friction and manage heavy fluid velocities at operational line pressures up to 50 PSI, the assembly ensures the equipment pad operates at peak efficiency. The physical dry weight of this Pentair 1.5" Hi-Flow Diverter with O-Ring is approximately 0.42 pounds (roughly 6.72 ounces, with a packaged shipping weight of approximately 0.60 pounds), providing pool professionals and DIY homeowners with an exceptionally rugged, durable, and critical mechanical solution for flawless pool water management.
