Waterway Plastics 805-0000 Lid to Body O-Ring

What This Part Is Used For
The Waterway Plastics 805-0000 Lid to Body O-Ring is a sealing gasket installed between the pump lid and the pump body on select Waterway pump models. It forms the primary seal that allows the pump to maintain suction during operation. This O-Ring is seated in the pump body or lid groove and compressed when the lid is secured. It plays a direct role in pump priming and circulation stability.

Why This Part Matters
If this O-Ring is worn, air can enter the pump housing and disrupt circulation. This often results in bubbles in the pump basket, noisy operation, or loss of prime. Replacing the O-Ring is a simple service step that prevents unnecessary pump replacement. OEM sizing is critical for proper sealing pressure.
