APC APCO2445 SPX735G Valve O-Ring for Hayward & Backwash Valves

Ensure a reliable, watertight seal on your pool and spa filter multiport or backwash valves with the APC APCO2445 SPX735G Valve O-Ring. Manufactured from durable nitrile rubber to withstand continuous pool chemical exposure and pressure, this replacement O-ring restores optimal performance and prevents costly water leaks in your filtration system.

🚩 PRO TIP: Always inspect and clean the O-ring groove on your multiport or backwash valve cover before installing a new O-ring. Applying a thin layer of silicone-based pool lubricant ensures a proper seal, prevents pinching or twisting during assembly, and significantly extends the service life of the rubber.
