The Hayward SPX2300Z4 Strainer Cover O-Ring is a genuine replacement seal designed for Hayward MaxFlo XL and compatible MaxFlo VS pool and spa pumps, helping preserve a watertight seal between the pump strainer lid and housing to prevent leaks and maintain proper suction. As an OEM-built component engineered to match original Hayward specifications, this O-ring restores original sealing performance that can deteriorate over time due to wear, chemical exposure, or age, ensuring your pump operates efficiently without drawing in air or leaking water. Ideal for routine maintenance or part refresh on systems like the MaxFlo XL SP2300X series and MaxFlo VS SP2300VSP models, the durable elastomer construction withstands repeated use and typical pool environments.
