The Aladdin O-497 Tank O-Ring delivers a critical seal for Pentair Clean and Clear Plus, FNS Plus, and Quad DE pool and spa filters. Seated inside the filter tank assembly, this O-ring locks out air and water leaks so your system holds proper pressure and filters at full capacity. Molded from long-wearing rubber with an inside diameter of 20-1/8 inches and a thickness of 1/2 inches, it forms a firm, gap-free barrier between tank halves. Swapping in a fresh O-ring on a regular schedule is one of the most effective ways to protect filtration performance and keep your water quality consistently high.

• Broad Filter Compatibility: Fits Pentair Clean and Clear Plus, FNS Plus, and Quad DE filter models, covering a wide range of pool and spa setups.
• Heavy-Duty Rubber Construction: Molded from tough rubber that resists compression set and chemical attack for extended service intervals.
