It measures 1-3\/4 in. inside diameter by 2 in. outside diameter by 1\/8 in. thick, and it is the genuine Pentair rubber part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich filters\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003ePentair specifies it for Clean and Clear Plus filters manufactured after 5\/21\/05, and lists the same ring among the Mytilus B fiberglass cartridge filter parts.

Once the rubber has hardened and taken a set, it cannot fill the gap between the plug and the tank, and no amount of extra torque will make it. It just risks cracking the plug or the boss it threads into.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eClean the seat, fit the new ring and add a light coat of silicone o-ring lubricant so it seats evenly and does not twist as the plug goes back in.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48625721671892,"sku":"PAC-051-1478","price":5.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_b58631ec-6781-4c56-9d03-a4442de0fffe.png?v=1788689931","url":"https:\/\/www.activepoolsupply.com\/products\/drain-plug-o-ring","provider":"Active Pool Supply","version":"1.0","type":"link"}
