About This Item

The Hayward Filter Head O-Ring (CX800F) is the OEM replacement sealing O-ring for the filter head on Hayward Star-Clear II cartridge filters.

IMPORTANT: LUBRICATION REQUIRED — SOLD SEPARATELY
Always lubricate this O-ring with a silicone-based lubricant before installation. Browse our Pool Plumbing Lubricants for a compatible silicone lubricant.

This O-ring seals the filter head assembly on the Star-Clear II cartridge filter, maintaining a watertight closure at the head-to-body joint and preventing pressurised water from bypassing the filter element.

Poolaroo Pro Tip

Before fitting this O-ring, inspect the filter head seating groove for any debris, cracking, or deformation. A clean, undamaged groove is essential for a leak-free seal. Apply a thin, even coat of a silicone-based lubricant — avoid petroleum-based products, which will cause the rubber to swell and fail prematurely. Find a compatible lubricant in our Pool Plumbing Lubricants collection.
