{"product_id":"rk-774-774dcda-ck1-6-1st-cam-check","title":"RK 774\/774DCDA CK1 6\"  1st Cam Check","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":49796765942037,"sku":"0888821","price":534.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0874\/6506\/6773\/files\/190750.jpg?v=1781622090","url":"https:\/\/www.backflowpreventer.com\/products\/rk-774-774dcda-ck1-6-1st-cam-check","provider":"Water Specialties Company","version":"1.0","type":"link"}
