Hayward Cover O-Ring (Viton) for Automatic Chlorine Feeders CL100 CL110 CL110ABG | CLX110K

Description

The Hayward Cover O-Ring in Viton (CLX110K) is the OEM replacement lid seal for Hayward Automatic Chlorine Feeders, maintaining a watertight closure at the feeder cover to prevent chemical leaks and maintain proper internal pressure during operation.

IMPORTANT: LUBRICATION REQUIRED — SOLD SEPARATELY
Always lubricate this O-ring with a silicone-based lubricant before installation to ensure a proper seal and prevent premature degradation. Browse our Pool Plumbing Lubricants for a compatible silicone lubricant.

This Viton O-ring seats in the cover groove of the chlorine feeder, creating a chemical-resistant seal that keeps chlorinated water contained within the feeder body. Viton material provides superior resistance to the harsh oxidizing environment inside a chlorinator compared to standard EPDM rubber, making it the appropriate choice for this application.

Compatibility is based on Hayward parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment’s manual or on the original part itself before ordering.

Poolaroo Pro Tip

When replacing this O-ring, clean the cover groove thoroughly to remove any chemical residue or old lubricant before seating the new seal. Apply a thin, even coat of silicone-based lubricant — never petroleum-based products, which degrade Viton — to the O-ring before closing the feeder cover. Browse our Pool Plumbing Lubricants for a compatible option. Inspect this O-ring at the start of each season; a worn or flattened seal is the most common cause of chemical leaks at the feeder lid.
