Why Replace Your Canister Filter O-Ring?
Over time, filter O-rings can become worn, dry, or lose their sealing ability. Replacing a damaged O-ring helps restore a proper seal and reduces the risk of leaks during filter operation. Regular inspection and replacement of worn seals can also help maintain reliable canister filter performance.
