Safeguard the seal on your Pentair filter system with the genuine Tank O-Ring 39010200. This factory-original rubber gasket is precisely manufactured with a 20-1/8 inch inside diameter and 1/2 inch cross-section thickness to deliver a flawless fit on Pentair Clean and Clear Plus, FNS Plus, and Quad DE filter tanks. Positioned at the tank clamp junction, it forms a watertight barrier that prevents air infiltration and water bypass, preserving proper operating pressure within the filtration system. The resilient rubber composition resists stretching, chemical degradation, and pressure cycling, giving you a dependable seal that lasts. Periodic replacement of this O-ring is a smart maintenance practice that protects water clarity and avoids performance-robbing pressure drops.
