{"product_id":"rk-774-774dcda-c-2-1-2-4-cover-kit","title":"RK 774\/774DCDA C 2 1\/2 - 4\"  Cover Kit","description":"Series 774 Series Double Check Valve Assemblies began production in 1998. Sizes run from 2 1\/2\" - 12\" and are all stainless steel body devices. Please be sure which model you have as the 774 and 774X use different repair parts. They utilize a single Victaulic cover with two self contained plastic cam checks that thread into the body. There are no rubber repair kits available for the 2 1\/2 - 6\" sizes, only complete cam checks. Although specialty tools are not required for servicing the device, there is a handy cam check tool available, designed to save time and prevent damage to the cam checks.\u003cbr\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/fireresq-documents.s3.amazonaws.com\/wsc\/lead-free-compliant.png\"\u003e\u003c\/p\u003e\u003cb\u003e\u003c\/b\u003e","brand":"Water Specialties Company","offers":[{"title":"Default Title","offer_id":49796769022229,"sku":"0888824","price":572.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0874\/6506\/6773\/files\/190206.jpg?v=1778600002","url":"https:\/\/www.backflowpreventer.com\/products\/rk-774-774dcda-c-2-1-2-4-cover-kit","provider":"Water Specialties Company","version":"1.0","type":"link"}
