It measures 2-5\/8 inches inside diameter and 2-13\/16 inches outside diameter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere it sits\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe tail piece is the fitting that the union nut pulls up against, and this o-ring is the seal at that face. It is a small part carrying the entire joint. When it flattens with age, takes a nick from grit, or gets pinched during reassembly, the union weeps and no amount of extra torque on the nut stops it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCheck the size\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eUnion o-rings in adjacent sizes look almost identical in the hand. Measure the old one across the inside and the outside and compare it against 2-5\/8 inches and 2-13\/16 inches before ordering. If a union is being opened anyway for pump or filter work, renewing the o-ring while it is apart is cheap insurance.\u003c\/p\u003e","brand":"Waterway","offers":[{"title":"Default Title","offer_id":48633455771860,"sku":"WWP-85-8275","price":2.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_bd758548-69cb-4cc1-a63a-9a53a17a5ec2.jpg?v=1788805004","url":"https:\/\/www.activepoolsupply.com\/products\/2-tail-piece-o-ring","provider":"Active Pool Supply","version":"1.0","type":"link"}
