Hayward SX200Z6 O-Ring

What This Part Is Used For
The Hayward SX200Z6 is an O-ring used on compatible Hayward sand filter components. It seals a connection point on the filter assembly so the system holds water and pressure during normal filtration and backwashing. This seal is used on the filter side of the equipment pad.

Why This Part Matters
When an O-ring flattens or cracks, small leaks start showing up after service or winterizing. A bad seal can also pull air and create unstable flow depending on the plumbing layout. Replacing the correct O-ring restores sealing without overtightening clamps or fittings. It is one of the most common fixes for repeat drips that show up only while the pump is running.

Key Features and Specifications

• Manufacturer part number: SX200Z6
• O-ring seal for compatible Hayward sand filter components
• Used to prevent leaks at sealed filter joints and connections
• Common replacement during filter service and rebuilds
• Equipment pad service part for restoring watertight sealing

Installation and Fitment Guidance
Turn off the pump and fully relieve filter pressure before removing any sealed components. Clean the groove and seating surfaces so the O-ring sits flat and does not pinch on reassembly. Confirm by manufacturer part number before ordering.

About the Hayward Brand

Their filtration products integrate with Hayward valves and circulation equipment used across many pool pads. This compatibility makes routine maintenance and part replacement more predictable for service pros. Hayward replacement parts are widely supported throughout the pool industry.

Common Service Context
Techs typically replace this O-ring when a filter starts dripping after being opened for service or when an old seal looks flattened and brittle. It is often identified during spring startup when seals begin leaking under pressure.
