This fitting connects 7\/8 inch copper tubing to 7\/8 inch copper tubing, providing a reliable, leak-resistant joint in refrigerant line sets and related piping assemblies. The roll stop feature positions the tube end consistently during installation, ensuring proper depth and alignment before brazing. Constructed entirely from copper, this coupling meets industry standards for both dimensional accuracy and material composition. HVAC technicians and refrigeration mechanics use this fitting during new installations, line set extensions, and field repairs.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for residential and light commercial HVAC and refrigeration applications where 7\/8 inch copper tubing is specified. It is commonly installed in suction line connections, line set assemblies, and refrigerant piping where a straight, same-size copper-to-copper joint is required. The roll stop eliminates guesswork on tube insertion depth, which is especially useful in tight or overhead installation scenarios where visual confirmation is limited.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRoll stop design controls tube insertion depth for consistent, repeatable joints\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch copper x 7\/8 inch copper connection for same-size tube joining\u003c\/li\u003e\n  \u003cli\u003eFull copper construction meets industry dimensional and material composition standards\u003c\/li\u003e\n  \u003cli\u003eSuitable for brazing in refrigerant and HVAC copper tubing applications\u003c\/li\u003e\n  \u003cli\u003eCertified to industry standards for dimensions and material composition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and field-use fitting for HVAC and refrigeration systems utilizing 7\/8 inch copper tubing in refrigerant line set or piping assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or refrigeration mechanic. Recover all refrigerant and depressurize the system before cutting or opening any refrigerant line. Clean and deburr tube ends before insertion to the roll stop, and use nitrogen purge during brazing to prevent internal oxidation scaling. Follow applicable mechanical codes and local jurisdiction requirements for refrigerant piping work.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 7\/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  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Coupling with Roll Stop\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: da03rs-08\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DirectedAir","offers":[{"title":"Default Title","offer_id":51150716666162,"sku":"DA03RS-08","price":49.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305988988.jpg?v=1778616776","url":"https:\/\/voomisupply.com\/products\/directedair-da03rs-08-copper-coupling-7-8-in-copper-x-7-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
