The flat section is 3\/32 inch. Measured across the whole ring, including the o-ring extension, it is 3\/16 inch. If you are comparing against a ring you already have in hand, measure the flat part to make the match.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA union gasket is cheap and the leak it causes is not. Once the old ring has taken a set, gone hard or split, it will not seal again no matter how much the union is tightened, so it is worth replacing whenever the connection is opened.\u003c\/p\u003e","brand":"Waterway","offers":[{"title":"Default Title","offer_id":48627738935508,"sku":"WWP-851-8097","price":4.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_5f50363a-8be9-45cd-b525-99ddaf1981b9.jpg?v=1788727577","url":"https:\/\/www.activepoolsupply.com\/products\/2-heater-o-ring-gasket","provider":"Active Pool Supply","version":"1.0","type":"link"}
