Key Benefits

• Full OEM-Grade Seal Package: Supplies every O-ring corresponding to OEM O-513, covering all sealing points in push-pull and slide-style backwash valves in a single convenient kit.
• Restores Watertight Backwash Function: Swaps out aged or brittle seals to re-establish firm contact surfaces, stopping water bypass and ensuring backwash cycles run at full effectiveness.
• Chemically Hardy Elastomer Composition: Produced from top-tier, flexible rubber compounds engineered to withstand chlorine, ozone, and other pool treatment chemicals while retaining elasticity through countless cycles.
• Virtually No Downtime: Slides into valve grooves without specialized tooling or machining, making it a practical choice for both planned service intervals and urgent seal failures.
• Extends Valve Assembly Lifespan: Prompt seal renewal reduces mechanical stress on the entire backwash assembly, promoting smoother actuation and adding service years to the valve system.
