Hayward SPX1705Z1 Housing O-Ring Gasket

What This Part Is Used For
The Hayward SPX1705Z1 is a housing O-ring gasket used to seal the pump housing joint on compatible Hayward pumps. It sits in the groove where the housing sections mate to prevent water leaks. This gasket is part of the wet end sealing surface.

Why This Part Matters
A flattened or cracked O-ring can drip under pressure or pull air when the pump shuts off and cools down. Leaks around the housing joint can lead to water loss and premature corrosion around the motor area. Replacing the gasket helps restore a clean, dependable seal.
