It measures approximately 18-1\/2 in. inside diameter with a 7\/16 in. cross section, and it replaces the original 152127 o-ring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA DE filter tank is two halves held together by a band clamp, and the o-ring in that joint is the only thing keeping filtered water inside. When it hardens, flattens or splits, the tank drips under pressure and the clamp gets blamed for it. A new o-ring is the first and cheapest fix.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCross references\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis part is also carried under the numbers 4600-2127 and 90-423-1184, so if the tag on your old ring or an older invoice shows one of those, this is the same seal.\u003c\/p\u003e\u003cp\u003eFit it clean and dry into the groove, seat it evenly all the way round, then bring the clamp up gradually rather than tightening one side first.\u003c\/p\u003e","brand":"Aladdin","offers":[{"title":"Default Title","offer_id":48626385944788,"sku":"SPG-601-1118","price":14.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_c04a30c6-aee1-4414-9ef4-a5fa4125bd28.jpg?v=1788709635","url":"https:\/\/www.activepoolsupply.com\/products\/tank-o-ring-1","provider":"Active Pool Supply","version":"1.0","type":"link"}
