It measures 2-3\/8 inches on the inside diameter with a 3\/16 inch cord thickness, and it is molded rubber.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere it goes\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIt seats in the union groove between the pump port and the union nut, on Hayward TriStar models SP3200 and SP3200EE and on Northstar pumps. Both the suction and discharge unions take the same o-ring, so a pump that has been apart usually wants two.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eUnion o-rings take heat every time the pump runs and eventually go hard, flatten into the groove, or crack. Once that happens the union will keep weeping no matter how hard the nut is tightened, and overtightening only cracks the nut. Fit a fresh o-ring with a light coat of silicone lubricant and hand tighten the union.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48627848347860,"sku":"HAY-101-1404","price":22.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_a425856f-72c9-4dfa-a844-d5a8628b4505.png?v=1788728223","url":"https:\/\/www.activepoolsupply.com\/products\/o-ring-2-3-8-id-1","provider":"Active Pool Supply","version":"1.0","type":"link"}
