Upgrade your pool pump seal with Koatukys 357255 Lid O-Ring

Designed as a superior rebuild part, this Koatukys lid O-ring is engineered to fit a wide range of Pentair Sta-Rite configurations, including OptiFlo, SuperMax, and SuperFlo models. The upgrade aligns with the pump housing to help restore airtight performance and consistent filtration.

Constructed from a premium rubber compound, the O-ring resists chlorine and UV exposure, helping it endure the demanding conditions of outdoor pools. The reinforced profile reduces the risk of cracking, shrinking, or deformation as temperatures swing from cool mornings to hot afternoons.
