Pool Pump Strainer Cover O-Ring | Housing Lid Gasket

This replacement O-ring seals the connection between the strainer housing cover and pump body on Swimline above-ground pool pumps. Over time, O-rings can dry out, crack, or lose their flexibility—leading to air leaks that reduce pump suction and filtration efficiency.

Swapping in a fresh O-ring restores the airtight seal your pump needs to operate at full capacity. Simple to install with no tools required.
