It measures 18-5\/16 inch on the inside diameter with a 9\/16 inch cross section, and it is listed as a substitute for part number 071442.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it seals\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA split tank filter is two halves clamped together, and the tank o-ring is the only thing holding pressure at that joint. Over a few seasons the ring takes a set, flattens into the groove and stops springing back. Once that happens the filter weeps or sprays at the band clamp every time the pump starts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is a generic replacement rather than the factory branded part. It carries the same dimensions, so measure the old ring, 18-5\/16 inch inside and 9\/16 inch thick, and confirm you have the 18 inch tank. Lubricate the new ring before you close the tank so it seats evenly in the groove.\u003c\/p\u003e","brand":"Aladdin","offers":[{"title":"Default Title","offer_id":48628828471508,"sku":"SPG-601-1233","price":16.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_da472ab9-4729-4a29-8d42-d5c3edfb8878.jpg?v=1788753455","url":"https:\/\/www.activepoolsupply.com\/products\/generic-o-ring-tank-redline","provider":"Active Pool Supply","version":"1.0","type":"link"}
