Description
Jandy R0462700 Tank Top O-Ring – CS Series Cartridge Filter Seal
Part R0462700 — a genuine replacement O-ring designed for use with Jandy CS Series cartridge pool and spa filters. This seal ensures a tight, leak-proof closure between the filter tank lid and body.
Key Features
- Precision-molded O-ring made to fit Jandy CS Series filter tanks (CS100, CS150, CS200, CS250).
- Forms a secure, watertight seal — prevents leaks and maintains proper filter pressure and performance.
- Durable, chemical-resistant rubber construction suitable for pool water environments.
- Simple to install — ideal when the original seal is worn, cracked, or leaks after clamping.
Typical Applications
Used whenever a CS Series filter shows leaks at the tank lid, draws air, loses pressure, or fails to seal properly after maintenance. Also recommended as a preventive replacement during regular maintenance or media changes to ensure ongoing filter integrity.
Installation Notes
Before installing, depressurize and drain the filter tank. Remove the old O-ring and clean the sealing surfaces thoroughly. Lightly lubricate the new O-ring with a pool-safe lubricant, seat it correctly in the groove, reassemble the tank, and tighten the clamp evenly. After startup, inspect for leaks or pressure loss to confirm a proper seal.
Why Choose This O-Ring?
Using the correct O-ring maintains filter performance and protects against water leaks, air intrusion, and potential damage to the filter housing. It’s a low-cost, high-impact maintenance part that helps extend the life and reliability of your filtration system.
Maintenance Tips
- Inspect the seal each time you open the tank — especially if you flush media or service the filter.
- Replace the O-ring if it shows signs of flat spots, cracks, or chemical degradation.
- Keep a spare O-ring on hand to minimize downtime during unexpected leaks or maintenance.
