Zodiac – Tank top O-ring – R0462701

The Zodiac R0462701 is a genuine OEM replacement tank top O-ring designed for use with Zodiac (formerly Jandy Waterpik) CS-series cartridge filters. This O-ring forms the critical watertight seal between the filter tank body and its top lid, preventing pressurised water from escaping around the filter head. Without an intact and correctly fitted O-ring, the filter will leak at the tank joint, compromising system pressure and pool water circulation. Replacing a worn, cracked, or deformed O-ring with this genuine Zodiac part restores the seal to factory specification and ensures reliable, leak-free filtration performance.

Technical characteristics and compatibility

This O-ring is manufactured to precise dimensional tolerances to match the tank top groove geometry of the CS-series filter range. It is produced from a durable elastomeric compound selected to withstand prolonged exposure to pool water, chlorine, and fluctuating operating pressures typical of residential pool filtration systems. The material resists compression set over time, maintaining an effective seal through repeated filter cleaning cycles that require opening and reseating the tank lid. The part number R0462701 is the direct successor reference to the earlier R0462700, and is confirmed compatible with the following Zodiac CS-series cartridge filters: CS100, CS150, CS200, and CS250. Always verify compatibility against your filter model number before ordering.

Suitability and practical buying guidance

This O-ring is intended for residential swimming pool owners and service technicians who maintain Zodiac CS-series cartridge filter systems. It is the correct service part to replace whenever a visible leak is detected at the tank lid joint, when the O-ring shows signs of flattening, cracking, or surface degradation, or as part of a routine preventive maintenance programme. Applying a thin coating of O-ring lubricant (silicone-based, pool-compatible) at installation will extend service life and make future lid removal easier. Because this is a genuine Zodiac replacement part, it guarantees a precise fit without modification and maintains the manufacturer’s intended performance standards for the CS filter series.
