Sized at 3\/4 inch CxC (cup by cup), the fitting features solder cups on both ends and an internal dimple stop that automatically positions the tube at the correct insertion depth. This ensures consistent, repeatable joints and reduces the risk of tube over-insertion. Sold in a bag of 10 fittings, this coupling is a standard item for residential and commercial plumbing rough-in and repair work performed by licensed plumbers and pipefitters.\u003c\/p\u003e\n\u003cp\u003eThe W00755J is suited for potable water supply lines, hydronic heating distribution piping, and general copper pressure systems where a reliable tube-to-tube connection is required. The lead-free construction meets regulatory requirements for use in drinking water applications. The 10-piece bag format makes it practical for service vans and job-site use where multiple joints are needed in a single run.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLead-free construction meets Safe Drinking Water Act requirements for potable water systems\u003c\/li\u003e\n  \u003cli\u003eInternal dimple stop sets tube insertion depth automatically for consistent solder joints\u003c\/li\u003e\n  \u003cli\u003eSolder cup ends on both sides accept standard 3\/4 inch copper tube for sweat connections\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch CxC configuration connects two lengths of copper tube in a straight run\u003c\/li\u003e\n  \u003cli\u003eSold in a bag of 10 fittings for multi-joint jobs and service stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solder pressure fitting compatible with standard 3\/4 inch copper tube used in residential and commercial plumbing pressure systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off the water supply and depressurize and drain the line before cutting and fitting. Clean tube ends and fitting cups with emery cloth, apply flux, and sweat-solder the joint per standard copper joining practice. Do not apply heat to the fitting before flux is applied, and allow the joint to cool fully before restoring system pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: CxC (Cup by Cup) Solder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead-Free\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10 fittings per bag\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: PK (Package)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity per Case\u003c\/strong\u003e: 12 bags\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NIBCO INC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: W00755J\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51525400199474,"sku":"W00755J","price":112.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77e0ab412cc8328385ad598eafccf648_43672ac9-d631-4642-a460-d2060cf5e42e.jpg?v=1785472693","url":"https:\/\/voomisupply.com\/products\/nibco-inc-w00755j-3-4-inch-cxc-copper-coupling-with-stop","provider":"Voomi Supply","version":"1.0","type":"link"}
