It transitions from a 7\/8 inch connection on one end to a 3\/4 inch connection on the other, both in copper. The full copper construction provides reliable corrosion resistance and thermal conductivity suited to refrigerant line sets, ACR tubing, and similar trade applications. HVAC technicians and plumbers install this fitting during system assembly, line set routing, or service work where a diameter reduction is required between two copper sections.\u003c\/p\u003e\u003cp\u003eThis reducing coupling is commonly used in residential and light commercial HVAC systems, refrigeration line sets, and copper plumbing installations where a controlled diameter transition is needed. It is appropriate for sweat or braze connections depending on the application and local code requirements. The fitting is manufactured to industry standards for both dimensional accuracy and material composition, making it a direct fit in standard copper tube work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTransitions 7\/8 inch copper to 3\/4 inch copper in a single fitting\u003c\/li\u003e\n\u003cli\u003eFull copper construction for corrosion resistance and thermal compatibility\u003c\/li\u003e\n\u003cli\u003eManufactured to industry dimensional and material composition standards\u003c\/li\u003e\n\u003cli\u003eSuitable for refrigerant line sets, ACR tubing, and copper plumbing applications\u003c\/li\u003e\n\u003cli\u003eAccepts sweat or braze joining methods per application requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for copper tube systems requiring a 7\/8 inch to 3\/4 inch reducing connection.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis fitting is typically installed by licensed HVAC technicians or journeyman plumbers. Recover and isolate any refrigerant or shut off fluid supply before cutting into an existing line. Use appropriate flux and solder or brazing alloy per ASHRAE, IFGC, or IPC guidelines for the specific application. Do not over-heat the fitting during brazing, as excessive heat can affect material integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 3\/4 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-08x07\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DirectedAir","offers":[{"title":"Default Title","offer_id":51149769179442,"sku":"DA03R-08X07","price":55.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305987358.jpg?v=1778601057","url":"https:\/\/voomisupply.com\/products\/directedair-da03r-08x07-reducing-coupling-7-8-x-3-4-copper","provider":"Voomi Supply","version":"1.0","type":"link"}
