It measures 6-1\/8 in. on the outside diameter, 5-9\/16 in. on the inside diameter, and 9\/32 in. thick.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eGet the right one\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNature2 uses two different lid o-rings and they are easy to confuse. This one suits the two piece locking ring cap. The o-ring for the one piece lid is larger in diameter but not as thick, and carries the part number W13061. Check the cap on your unit before ordering rather than going by diameter alone.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe o-ring is what keeps the cap sealed under system pressure. Once it flattens, hardens or takes a nick, water starts weeping from under the lid and no amount of tightening fixes it. It is a cheap part to keep on hand and worth swapping any time the unit is opened for a cartridge change.\u003c\/p\u003e","brand":"Zodiac","offers":[{"title":"Default Title","offer_id":48634423705812,"sku":"FOU-451-1047","price":24.91,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_327eec8a-3f09-4046-93ef-64a95e588cd0.jpg?v=1788830364","url":"https:\/\/www.activepoolsupply.com\/products\/o-ring-for-2-piece-locking-ring-cap","provider":"Active Pool Supply","version":"1.0","type":"link"}
