{"product_id":"2-union-o-ring","title":"Jandy 2\" Union O-Ring","description":"\u003cp\u003eThe Jandy R0412700 is the o-ring for the 2 inch union, the seal that sits in the union face and holds the joint watertight. It is the genuine Jandy part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere it is used\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eJandy uses 2 inch unions throughout the equipment pad, and this is the o-ring listed for that connection, including the 2 inch LX unions at an AquaPure cell. It is the part that comes out when a union is opened for winterizing or for cleaning a cell, and the part most likely to be pinched or nicked on the way back together.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe mistake to avoid\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWhen a union drips, the instinct is to lean on the collar. That does not work. A union seals on the o-ring, not on clamping force, and cranking the collar down distorts the faces and can crack the nut. If it weeps after hand tightening, the o-ring is done.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eClean the groove, check that no grit is trapped in it, and put a thin film of silicone based lubricant on the new o-ring before assembly. It seats more evenly and comes apart far more easily next time.\u003c\/p\u003e","brand":"Zodiac","offers":[{"title":"Default Title","offer_id":48625748705492,"sku":"JDY-451-0203","price":10.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_e7dd3268-a4f2-46f4-a833-3171ed29c36b.jpg?v=1788691570","url":"https:\/\/www.activepoolsupply.com\/products\/2-union-o-ring","provider":"Active Pool Supply","version":"1.0","type":"link"}
