It is a small part with an outsized job, since it is the only thing holding water inside the joint once the pump is running.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAny weep or drip at the heater connection points at the o-ring first. Heat cycles harden the rubber and the ring takes a permanent set in its groove, so an old ring that has been disturbed rarely reseals. Fit a new one whenever the heater has been opened up.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWipe the groove and the mating face clean before the ring goes in, and check that nothing has been nicked. If you lubricate it, use a silicone based lubricant, since petroleum products attack o-ring rubber.\u003c\/p\u003e","brand":"Balboa Instruments","offers":[{"title":"Default Title","offer_id":48628941848788,"sku":"BAL-851-1302","price":5.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_ffb74167-14cd-4d7b-8e00-fb6d6ae17335.jpg?v=1788758283","url":"https:\/\/www.activepoolsupply.com\/products\/heater-o-ring-2","provider":"Active Pool Supply","version":"1.0","type":"link"}
