It connects a 1-3\/8 inch copper socket (C) end to a 1-1\/4 inch male pipe thread (MPT) fitting, allowing plumbers to transition from soldered copper tubing to threaded pipe connections. This adapter is a standard component in potable water supply lines, hydronic heating systems, and general plumbing rough-in work where a solder-end-to-thread connection is required.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for plumbing installations where copper tubing must transition to threaded iron, brass, or steel pipe fittings. Typical applications include water supply risers, boiler connections, and fixture supply lines in both new construction and retrofit plumbing projects. Sold in a box quantity of 20, this adapter is practical for contractors stocking common transition fittings on the job.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eC x MPT configuration allows direct solder-to-thread transitions without additional adapters\u003c\/li\u003e\n  \u003cli\u003e1-3\/8 inch copper socket inlet accepts standard copper tubing via sweat connection\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch MPT outlet threads directly onto female-threaded fittings or valves\u003c\/li\u003e\n  \u003cli\u003eCopper construction provides corrosion resistance in water service applications\u003c\/li\u003e\n  \u003cli\u003eBox quantity of 20 units supports contractor and wholesale purchasing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style copper sweat-to-male-thread adapter for use in standard plumbing systems requiring a 1-3\/8 inch C x 1-1\/4 inch MPT transition fitting.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off and depressurize the water supply before soldering. Clean and flux the copper socket end before applying heat, and apply thread sealant tape or pipe compound to the MPT threads before assembly. Avoid over-torquing the threaded connection, which can crack copper fittings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBasic Fitting Type\u003c\/strong\u003e: Adapter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecific Fitting Type\u003c\/strong\u003e: MPT Adapter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: C x MPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1-3\/8 inches x 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBox Quantity\u003c\/strong\u003e: 20\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: W1171\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NDL INDUSTRIES","offers":[{"title":"Default Title","offer_id":51383553818930,"sku":"W1171","price":18.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670912.jpg?v=1782600323","url":"https:\/\/voomisupply.com\/products\/ndl-industries-w1171-copper-male-adapter-1-3-8x1-1-4-c-x-mpt","provider":"Voomi Supply","version":"1.0","type":"link"}
