The rolled stop is an internal shoulder machined into the fitting body that positions each pipe end at the correct insertion depth, ensuring consistent, repeatable solder joints. This fitting is used by licensed plumbers and pipefitters working on copper supply, distribution, or hydronic piping. Its full copper construction provides the corrosion resistance and thermal conductivity that soldered copper systems demand.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for residential and light commercial plumbing installations where 4-1\/8 inch copper pipe is being joined, extended, or repaired. The C x C connection type requires standard soldering (sweat) technique on both ends. The rolled stop eliminates the need for a separate stop gauge, making it a practical choice for production plumbing work or service calls where speed and accuracy matter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRolled stop design positions pipe ends at correct depth for consistent solder joints\u003c\/li\u003e\n  \u003cli\u003eC x C connection on both ends — compatible with standard copper sweat fittings and pipe\u003c\/li\u003e\n  \u003cli\u003e4-1\/8 inch connection size for large-diameter copper piping applications\u003c\/li\u003e\n  \u003cli\u003eCopper construction offers corrosion resistance and reliable long-term performance in wet systems\u003c\/li\u003e\n  \u003cli\u003eSold individually — one fitting per box\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sweat coupling for use with 4-1\/8 inch nominal copper pipe in standard C x C plumbing configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber following local plumbing codes and IPC guidelines. Shut off and drain the water supply line before cutting or fitting pipe. Clean both pipe ends and fitting sockets thoroughly with emery cloth and flux before applying heat. Avoid overheating the fitting, as excessive heat can burn flux and result in a void or cold solder joint.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBasic Fitting Type\u003c\/strong\u003e: Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecific Fitting Type\u003c\/strong\u003e: Rolled Stop Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Connection Type\u003c\/strong\u003e: C X C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 4-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBox Quantity\u003c\/strong\u003e: 1\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: NDL INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: w10107\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NDL INDUSTRIES","offers":[{"title":"Default Title","offer_id":51468119212338,"sku":"W10107","price":73.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945906.jpg?v=1783913755","url":"https:\/\/voomisupply.com\/products\/ndl-industries-w10107-rolled-stop-copper-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
