It contains two couplers, two nuts and two O-rings, which is a complete pair of unions covering both ends of the cell.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat Pentair lists it for\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe set is listed for the IntelliChlor salt chlorine generator and for the EasyTouch PS4 and PSL4 control systems.

They are opened and closed more than any other joint on the pad, so the O-rings flatten, the nuts crack and the threads wear. A weeping union is usually the first sign.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoing the job once\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eBecause the set covers both ends with new seals, hardware and couplers, it puts the cell back on fresh joints rather than reusing a suspect one on the other side.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48626381684948,"sku":"PAC-451-0595","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_aa1e60f7-4cb1-4bf8-a08e-23423d8ec0e1.png?v=1788709526","url":"https:\/\/www.activepoolsupply.com\/products\/intellichlor-relplacement-unions-contains-2-o-rings-2-couplers-2-nuts","provider":"Active Pool Supply","version":"1.0","type":"link"}
