This is not just a basic round gasket. It is a red-line channel O-ring designed to match the original sealing setup on specific Pentair tank systems. When the old seal is brittle, stretched, or leaking, replacing it with the correct OEM-style part is the right fix.\u003c\/p\u003e\n\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\u003cp\u003eBefore installing the new O-ring, clean the channel and inspect the clamp and tank sealing surfaces. A fresh seal will not solve leaks caused by debris, damage, or poor clamp alignment.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Tips\u003c\/h3\u003e\n\u003cp\u003eShut the system down fully and relieve all pressure before opening the tank. Confirm the filter model before ordering, seat the O-ring evenly in the channel, and avoid twisting or pinching it during reassembly.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":42388761051221,"sku":"071442Z","price":38.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.epoolsupply.com\/products\/pentair-18-channel-o-ring-kit-with-red-line-for-nautilus-plus-smbw-2000-071442z","provider":"ePoolSupply","version":"1.0","type":"link"}
