The o-ring is what closes it. It sits in salt water, it is warmed and cooled with every cycle, and it is compressed the whole time, so it hardens and takes a permanent set. When it does, the housing weeps, usually slowly enough that the first sign is white crust on the outside of the cell rather than an obvious drip.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWhenever the electrode comes out. Cells are pulled routinely for inspection and acid cleaning, and an o-ring that has been sitting compressed will rarely go back and reseal properly. Replacing it while everything is already apart costs a fraction of the trip back out to the pad. Seat it clean, free of grit, and use a silicone based lubricant rather than a petroleum grease. If the clear housing itself has cracked, the o-ring will not help; the housing body is a separate CompuPool part.\u003c\/p\u003e","brand":"CompuPool","offers":[{"title":"Default Title","offer_id":48634045497556,"sku":"PSU-135804","price":16.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_ff9501c0-8c72-48b4-a656-dc2ea5ac1166.jpg?v=1788825295","url":"https:\/\/www.activepoolsupply.com\/products\/compupool-electrode-o-ring-for-clear-cell-housing-jd363ecm","provider":"Active Pool Supply","version":"1.0","type":"link"}
