The Aladdin Rainbow Chlorinator Lid O-Ring (part number O-283) is a precision-manufactured seal designed to restore watertight integrity to chlorinator lids for the Rainbow / Pentair feeder series. Engineered from durable, chemical-resistant rubber, this O-ring creates a tight gasket seal between the chlorinator lid and housing, preventing leaks, pool water loss, and chemical exposure. Whether you’re servicing a residential pool or a larger spa system, this replacement ring ensures a reliable, leak-free closure to maintain safe chemical levels and system pressure.
-
Exact OEM Replacement: Engineered to match original Rainbow/Pentair dimensions (fits models 300, 302, 320, and related feeders) for a proper, secure fit.
-
Leak-Proof Seal: Creates a tight barrier under the chlorinator lid to prevent water or chemical leaks — essential for safety and maintaining consistent chlorine or bromine output.
-
Chemical-Resistant Rubber: Made from durable elastomer that resists pool chemicals, chlorine, and typical pool-environment stress to preserve flexibility and sealing integrity over time.
-
Simple DIY Installation: Fits directly into the lid groove without modification, enabling quick and easy replacement — ideal for maintenance or seasonal refresh.
-
Versatile Compatibility: Works with multiple Rainbow / Pentair feeders and chlorinator models (OEM equivalents include R172009, 154005), making it a broadly useful spare part.
