It is a generic equivalent of OEM part number 57007300 and may fit other Pentair model filters.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCheck the dimensions\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eFilter o-rings are easy to order by the wrong name and hard to get wrong by measurement. This ring has an inside diameter of 8-1\/16 in, an outside diameter of 8-11\/16 in and a cord thickness of 5\/16 in. Lay your old ring beside a tape and compare those three numbers before ordering. It is also cross referenced as O-342, 570073 and 4654-05, so an old invoice may list it under a different code.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eLid o-rings take heat, pressure and sunlight, and eventually go flat, hard or split at a nick. A ring in that state weeps at the lid or lets the filter pull air, and it is worth replacing every time the filter is opened for a cleaning or a media change rather than waiting for it to leak.\u003c\/p\u003e","brand":"Aladdin","offers":[{"title":"Default Title","offer_id":48628860944596,"sku":"SPG-601-1168","price":10.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_4df25157-4072-42be-a1ec-13b0b4f92c81.jpg?v=1788755587","url":"https:\/\/www.activepoolsupply.com\/products\/lid-o-ring-commander-series","provider":"Active Pool Supply","version":"1.0","type":"link"}
