It is the genuine Hayward part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSize\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eInside diameter 6-1\/2 in., thickness 3\/16 in. If you are measuring an old ring to confirm, allow for the fact that a ring which has taken a set reads slightly larger and thinner than the figures above.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to replace it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAn o-ring is a simple round gasket that seals two machined faces against each other. Here it seals the filter tank joint. Over the seasons the rubber hardens, flattens and loses its spring, and the joint begins to weep under pressure. A new ring is the fix, and because the tank has to be opened to change sand anyway, most techs replace it as part of a media change.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eClean both sealing faces, seat the ring square in its groove without stretching it, and use a silicone based o-ring lubricant. Petroleum grease attacks the rubber and shortens the life of the seal.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48625782128852,"sku":"HAY-051-2205","price":15.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_cd0d2b44-7a5a-4cdb-9056-04d07445ba2f.png?v=1788692113","url":"https:\/\/www.activepoolsupply.com\/products\/o-ring-s240","provider":"Active Pool Supply","version":"1.0","type":"link"}
