Hayward SX200Z5 O-Ring

What This Part Is Used For
The Hayward SX200Z5 is an O-ring used on compatible Hayward sand filter assemblies. It seals a specific joint or fitting on the filter so water stays contained under normal operating pressure. This seal is part of routine filter service and rebuild work.

Why This Part Matters
A worn O-ring is a common reason filters drip at seams and fittings, especially after winterizing and reopenings. Leaks at the filter can waste water and create pad damage over time. Replacing the correct O-ring restores a dependable seal without forcing hardware too tight. It also helps prevent air from being drawn into the system through a compromised joint.

Installation and Fitment Guidance
Shut the system down and relieve all filter pressure before opening the assembly. Clean the O-ring groove and seat the seal evenly to avoid pinching during reassembly. Confirm by manufacturer part number before ordering.
