Description
The genuine OEM Pentair SuperFlo Pump Lid O-Ring 357255 creates the watertight barrier between the pump lid and housing on Pentair SuperFlo and SuperMax pool pumps, including SuperFlo VS and VST models from both the pre-November 2020 and post-October 2020 production runs. Replacing a worn or compressed O-ring with this factory-specification part restores proper vacuum and pressure within the pump, preventing air leaks that degrade priming and flow performance. Compatible with both aboveground and inground pool and spa pump configurations, it is one of the most practical maintenance items any pool owner can keep on hand.
