Hayward CX800F Star-Clear II Filter Head O-Ring

What This Part Is Used For
The Hayward CX800F Star-Clear II Filter Head O-Ring seals the lid to the tank body on compatible Star-Clear II filter systems. It prevents water leaks during operation.

Why This Part Matters
A flattened or cracked O-ring can cause water to leak around the filter head. Replacing it restores a tight seal and stable pressure. This helps prevent pad flooding and air intrusion.
