Seal (O-Ring) under S-Swimm Pump Lid – 101.2×5.7 mm

The O-ring 101.2×5.7 mm is intended as a sealing element under the pre-filter lid of the S-Swimm pump. The precise dimensions ensure correct seating in the lid groove and an airtight seal at the pump’s operating pressure.

The seal material withstands chlorinated water and other pool preparations. Wear or deformation of the O-ring manifests itself as water leakage from the pre-filter lid area, which is the most common cause of a loss of pump performance.

Replacement of the O-ring is a quick and inexpensive preventive measure that is recommended each time the pre-filter is opened or at least once per season during a service inspection of the pump.
