Pentair SM and SMBW Brass Handle Extension

The Pentair SM and SMBW Brass Valve Handle Extension (Product #: 070971 / 070971Z) is a factory-original OEM replacement internal mechanical component engineered to optimize leverage and structural durability within heavy-duty pool and spa backwash networks. Explicitly designed for classic side-mounted Pentair, Purex, and PacFab SM and SMBW 2000 and 4000 series diatomaceous earth (D.E.) separation valves, this specialized extension segment bridges the external manual control lever with the internal tapered rotor assembly. Machined from premium, high-tensile structural brass alloy, the extension piece delivers outstanding mechanical yield strength, allowing pool service professionals and homeowners to smoothly depress and rotate the valve handle through its multi-port cleaning cycles without binding, flexing, or stripping under physical torque load. Its solid metallic matrix provides absolute rustproofing and total immunity to the corrosive humidity of pump rooms, severe seasonal temperature shifts, and localized exposure to highly concentrated pool sanitation chemistry such as chlorine shock, muriatic acid, and advanced salt-chlorine generation. The physical dry weight of this single Pentair SM and SMBW Brass Handle Extension is approximately 0.95 pounds (roughly 15.20 ounces, with a boxed retail shipping weight between 1.10 and 1.25 pounds depending on small-carton packaging material), providing a rugged, long-lasting hardware standard to maintain peak fluid-management control and effortless filter pad operation.
