SW-80-150 | Swimables SuperFlo Lid O-Ring | 357255

The Swimables SW-80-150 O-Ring is a direct replacement for Pentair part 357255 (aka #357 lid O-ring). It serves as the lid/seal gasket for the strainer cover (pump lid) on SuperFlo, SuperFlo VS, SuperMax, and OptiFlo pump series. This critical sealing ring prevents leaks at the pump’s lid interface, maintaining suction and keeping the pump wet end under pressure without weeping water. Molded from premium chemical-resistant elastomer, the ring is designed to resist chlorine, salt, UV, and repeated compressive stress. It’s a must-have maintenance item for any pump servicing or rebuild.

• Exact OEM Match for 357255 Lid Seal: Designed to replicate the original dimensions and material properties of Pentair’s #357 lid O-ring—ensuring a proper seal with no adjustment needed.

• Fits Multiple Pump Series: Compatible with Pentair SuperFlo, SuperFlo VS, SuperMax, and OptiFlo pumps, making it a versatile maintenance item across multiple platforms.

• Resilient Elastomer Construction: Built from durable, chemical-resistant material that withstands chlorine, UV, saltwater environments, and repeated compression cycles.

• Maintains Seal Integrity & Prevents Leaks: Restores a tight lid seal to prevent water from leaking out or air entering the pump pot, which could compromise performance.

• Easy to Replace & Maintain: Slips into the lid groove without modifications; swapping this O-ring can resolve common “wet pump lid” issues in minutes.
