Built to a 700 psi pressure rating, this fitting uses solder cups on both ends for a C x C (copper-to-copper) joint. It complies with ASME B16.22 and MSS SP-104 dimensional standards and is third-party certified to NSF\/ANSI 61 Annex G, making it suitable for potable water and medical gas applications. Licensed plumbers and mechanical contractors install this fitting in residential and commercial copper piping systems.\u003c\/p\u003e\n\u003cp\u003eThis coupling is used wherever two straight runs of 2-1\/2-inch copper tube must be joined end-to-end. The dimpled tube stop ensures consistent insertion depth and uniform solder joint geometry, which is especially important in larger-diameter applications where alignment matters. The fitting carries compliance with NFPA 99 Health Care Facilities Gas and Vacuum Systems and Compressed Gas Association Pamphlet G4.1, making it appropriate for medical gas piping installations in addition to standard plumbing and HVAC hydronic systems. It is manufactured domestically and is rated lead-free per applicable standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDimpled tube stop for consistent insertion depth and repeatable solder joint quality\u003c\/li\u003e\n  \u003cli\u003e700 psi pressure rating for high-demand plumbing and mechanical applications\u003c\/li\u003e\n  \u003cli\u003eWrot copper construction (ASTM B75 Alloy C12200)  -  dezincification resistant\u003c\/li\u003e\n  \u003cli\u003eThird-party certified to NSF\/ANSI 61 Annex G for potable water contact\u003c\/li\u003e\n  \u003cli\u003eCompliant with NFPA 99 and CGA Pamphlet G4.1 for medical gas service\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B16.22, MSS SP-104, and MSS SP-109 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sweat fitting for 2-1\/2-inch nominal copper tube in C x C configurations, suitable for potable water, HVAC hydronic, and medical gas piping systems where NSF\/ANSI 61 and NFPA 99 compliance is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Plumbing Code (IPC). Shut off and drain the system before cutting and fitting any sections of pipe. Clean all mating surfaces with emery cloth and apply flux before soldering; follow lead-free solder requirements for any potable water or medical gas application. For medical gas piping, additional qualification and documentation requirements under NFPA 99 apply.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: C x C (Solder Cup)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Coupling with Dimpled Tube Stop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Wrot Copper, ASTM B75 Alloy C12200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 700 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 600DS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: NSF\/ANSI 61 Annex G, ASME B16.22, MSS SP-104, MSS SP-109, NFPA 99, CGA Pamphlet G4.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Free\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Domestic (USA)\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: MUELLER STREAMLINE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: COCOUP212\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":68081828528434,"sku":"COCOUP212","price":38.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/66b83dbbba925d42407de6978452e3fb.jpg?v=1793146776","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-cocoup212-copper-coupling-2-1-2-in-c-x-c","provider":"Voomi Supply","version":"1.0","type":"link"}
