It is under system pressure the whole time the pump is running, so once it hardens, flattens or nicks, the joint starts to weep and salt water finds its way onto the pad.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWhenever the head comes off. The ring is a small part in front of an expensive cell, and disturbing an old o-ring is a good way to turn a working seal into a leaking one. A thin film of silicone o-ring lubricant on the new ring helps it settle into the groove without rolling.\u003c\/p\u003e","brand":"Balboa Instruments","offers":[{"title":"Default Title","offer_id":48627978797268,"sku":"ECM-451-1005","price":26.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_17b1e25e-f6d8-4969-aaae-f81b32df4434.jpg?v=1788732202","url":"https:\/\/www.activepoolsupply.com\/products\/eco-matic-o-ring-for-cell-head","provider":"Active Pool Supply","version":"1.0","type":"link"}
