This is a model-specific tank seal used to maintain the proper connection between filter body sections. When the original O-ring becomes brittle, stretched, or starts leaking, replacing it with the correct Pentair part is the right fix instead of guessing with an off-size substitute.\u003c\/p\u003e\n\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\u003cp\u003eBefore installing the new O-ring, clean the sealing channel and inspect the clamp and tank mating surfaces.
