Waterway Plastics 805-0164 EX2 Volute O-Ring

What This Part Is Used For
The Waterway Plastics 805-0164 EX2 Volute O-Ring is a sealing gasket used between the volute and housing on compatible Waterway EX2 pumps. It creates a watertight seal to prevent leaks at the pump body joint. This O-Ring is installed internally and compressed when the pump housing is secured. It is critical to pump integrity during normal operation.

Why This Part Matters
A worn or damaged volute O-Ring can allow water to leak from the pump housing. This can lead to air intrusion, loss of prime, or damage to surrounding equipment. Replacing the O-Ring restores proper sealing without replacing the entire pump. Using the correct OEM O-Ring ensures proper compression and long-term reliability.
