It transitions from a 1-1\/8 inch connection on one end to a 7\/8 inch connection on the other, allowing technicians to step down tubing size within a refrigeration, HVAC, or plumbing system. Both ends accept copper tubing and are suited for standard brazing or soldering installation methods. This fitting is manufactured to industry standards for dimensional accuracy and material composition, making it a reliable choice for field repair or new installation work.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is used in refrigerant line sets, copper piping systems, and HVAC equipment installations where a transition between 1-1\/8 inch and 7\/8 inch copper tubing is required. Typical applications include residential and light commercial air conditioning and refrigeration systems. It is installed by licensed HVAC technicians and plumbers working with copper distribution lines during equipment installation, system modification, or service repairs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions 1-1\/8 inch copper to 7\/8 inch copper in a single fitting\u003c\/li\u003e\n  \u003cli\u003eFull copper construction for compatibility with standard brazing and soldering processes\u003c\/li\u003e\n  \u003cli\u003eManufactured to industry dimensional and material composition standards\u003c\/li\u003e\n  \u003cli\u003eSuitable for refrigerant lines and copper fluid piping applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation copper reducing coupling for HVAC, refrigeration, and plumbing systems using 1-1\/8 inch and 7\/8 inch copper tubing connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber. Recover and isolate refrigerant before opening any refrigerant circuit, and shut off fluid supply before working on plumbing lines. Clean and deburr both tube ends before brazing or soldering to ensure a leak-free joint. Work should comply with applicable local mechanical codes and industry standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 1\u003c\/strong\u003e: Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 2\u003c\/strong\u003e: Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\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: DIRECTEDAIR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: da03r-11x08\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DirectedAir","offers":[{"title":"Default Title","offer_id":51150065762610,"sku":"DA03R-11X08","price":43.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305989004.jpg?v=1778605157","url":"https:\/\/voomisupply.com\/products\/directedair-da03r-11x08-reducing-coupling-copper","provider":"Voomi Supply","version":"1.0","type":"link"}
