The Swimables SW-26-731 is a precisely molded compression ring built as a direct substitute for Pentair Purex SM & SMBW 2000 series backwash valve components, matching OEM part number 070731Z. This ring re-establishes a firm, pressure-tight seal within the backwash valve assembly, preventing water bypass and protecting filtration efficiency. Manufactured from high-strength, chemically inert materials, it retains its shape and sealing properties through countless valve cycles and continuous exposure to treated pool water, helping extend the useful life of your entire filtration system.

Key Benefits

• Direct Fit for OEM Part 070731Z: Precision-manufactured to match the exact dimensions and tolerances of the original Pentair component used in SM and SMBW 2000 Series D.E. backwash valves.
• Pressure-Tight Sealing Surface: Delivers uniform compression across the valve interface to eliminate water bypass and preserve full filtration throughput.
• Chemically Inert Construction: Engineered from heavy-duty plastic that resists degradation from chlorine, salt, and other pool treatment chemicals over extended periods.
• Effortless Drop-In Swap: Replaces the worn ring quickly during standard maintenance, keeping service time short and your system back online fast.
• Essential Valve Seal Component: Functions as the primary compression interface within the valve body, preventing leaks that could compromise equipment and water quality.
