It is a small part in a hot, pressurized location, which is exactly why it is the piece that gives up first. Water weeping from the exchanger area is usually a compressed or hardened gasket rather than anything structural.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to fit new ones\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAny time the exchanger is opened, put new gaskets back in. A used O-ring has taken a set from being clamped and heat cycled, and reusing one to save a few dollars often means taking the heater apart a second time. The two per pack quantity matches the way the job is normally done.\u003c\/p\u003e","brand":"Raypak","offers":[{"title":"Default Title","offer_id":48627191546068,"sku":"RAY-151-3710","price":32.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_ec2ece26-573f-4eed-bd93-20f0c2ffd062.gif?v=1788719986","url":"https:\/\/www.activepoolsupply.com\/products\/o-ring-gasket","provider":"Active Pool Supply","version":"1.0","type":"link"}
