The CLX200K o-ring is the o-ring that seals the cap and cover of your chlorinator/feeder to the housing/canister. If your feeder is leaking water at the connection between the cap and housing, it’s time to replace your o-ring. Compatible with: Hayward CL200, CL220, and CL220BR Pool Chlorinator/Chemical Feeders. These CLX200K o-rings match OEM specs for size and material. They are molded throughout with Viton FKM rubber for long term durability and chlorine/bromine resistance. Unlike other o-rings which are made from inferior rubber materials or only feature a chlorine resistant surface/color coating, these CLX200K o-rings will hold up just like the ones that came in your Hayward unit when it was new. Pack contains two (2) CLX200K O-Rings. Manufactured and warrantied by Captain O-Ring LLC.
