Pentair Union Replacement Kit for 1-1/2" HiFlow Valves

Pentair 1.5" Hi-Flow™ Multiport Valve Union Replacement Kit (271096)

The Pentair Union Replacement Kit for 1-1/2" Hi-Flow™ Multiport Valves (Product #: 271096) is a specialized plumbing hardware package designed to establish clean, leak-free, and easily disconnectable pipe connections on residential pool sand and D.E. filtration systems. Engineered specifically for Pentair side-mount and top-mount multiport valves utilizing 1.5-inch plumbing configurations, this comprehensive kit allows pool service technicians and homeowners to quickly detach plumbing lines from the valve assembly for seasonal winterization, equipment upgrades, or interior valve maintenance without cutting any PVC pipes. Each component is injection-molded from a high-impact, UV-stabilized engineering polymer that provides total immunity to corrosive pool chemicals, heavy water scaling, and continuous outdoor weathering under standard operational pressures up to 50 PSI. The kit features a smart, modular design consisting of two heavy-duty threaded union nuts, two slip-socket union adapters that solvent-weld directly onto standard 1.5-inch schedule 40 PVC piping, and two custom-molded, high-density TPE o-rings that compress tightly within the union faces to create an absolute hydraulic seal without the use of messy thread sealants or Teflon tape. By replacing worn or cracked union fittings, this factory-original hardware pack restores optimal fluid velocities and prevents critical air leaks on the suction side or water weeping on the pressure side of the pool circulation loop. The dry product weight of the complete Pentair 1.5-inch Hi-Flow valve union replacement kit is approximately 0.8 pounds (with a boxed shipping weight of roughly 1.0 pound), providing a lightweight, incredibly robust, and convenient plumbing solution for modern pool equipment pads.
