The dimpled tube stop positions pipe ends at the correct insertion depth before soldering, helping ensure a consistent, leak-free joint. This fitting is intended for use in pressure piping systems and is installed by licensed plumbers and pipefitters working on residential and commercial water distribution, hydronic heating, or mechanical piping systems.\u003c\/p\u003e\u003cp\u003eThis coupling is suited for straight-run connections in 4-inch copper piping systems. The C x C end connections accept standard copper tubing on both ends, making it a common choice for repairs, extensions, or new rough-in work. At 4 inches, this fitting is typically found in commercial or industrial water service, large-diameter hydronic systems, and main distribution lines rather than typical residential branch lines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDimpled tube stop ensures consistent pipe insertion depth for repeatable solder joints\u003c\/li\u003e\n\u003cli\u003eCup-by-cup (C x C) ends accept standard copper tubing on both sides\u003c\/li\u003e\n\u003cli\u003e4-inch diameter suits large commercial and industrial piping applications\u003c\/li\u003e\n\u003cli\u003eCopper construction provides corrosion resistance in water service applications\u003c\/li\u003e\n\u003cli\u003eSweat-solder connection compatible with standard plumbing torch and flux technique\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style pressure fitting for use with standard 4-inch copper tubing in sweat-solder plumbing and mechanical piping systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber or pipefitter using standard torch, flux, and lead-free solder per local plumbing codes and ASTM B32 solder requirements. Shut off and drain the water supply completely before cutting into any existing line. Clean all mating surfaces with emery cloth and apply flux evenly before heating. Follow all applicable IPC and local code requirements for pressure testing after soldering.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: C x C (Cup by Cup, Sweat Solder)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Stop Style\u003c\/strong\u003e: Dimpled\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MUELLER STREAMLINE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: COCOUP4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51524672225586,"sku":"COCOUP4","price":81.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce9221624523c235c9b568f33e096793.jpg?v=1785454803","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-cocoup4-4-in-copper-coupling-c-x-c","provider":"Voomi Supply","version":"1.0","type":"link"}
