The roll stop feature provides a positive seat for consistent insertion depth, ensuring reliable, repeatable joints during brazing or soldering. Both connection ends are 3\/8 inch copper, making this a same-size inline coupling. Licensed HVAC technicians and refrigeration mechanics working on copper line set installations or repairs will find this fitting suited to standard field joinery work.\u003c\/p\u003e\u003cp\u003eThis coupling is intended for use in residential and light commercial HVAC and refrigeration piping systems where copper-to-copper connections are required. It is appropriate for new installations and service repairs involving 3\/8 inch copper tubing, including suction or liquid line work on split systems and other refrigerant circuits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRoll stop design provides a positive seat for controlled insertion depth and consistent joint quality\u003c\/li\u003e\n\u003cli\u003e3\/8 inch copper x 3\/8 inch copper same-size inline connection\u003c\/li\u003e\n\u003cli\u003eFull copper construction for compatibility with standard brazing and soldering procedures\u003c\/li\u003e\n\u003cli\u003eManufactured to industry dimensional and material composition standards\u003c\/li\u003e\n\u003cli\u003eSuitable for refrigerant line and HVAC piping applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 3\/8 inch copper tubing in residential and light commercial HVAC and refrigeration piping systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC or refrigeration technician. Recover and isolate refrigerant before cutting into an existing line set in accordance with EPA Section 608 regulations. Clean and deburr tubing ends before seating them fully against the roll stop, then braze or solder using appropriate flux and filler material per manufacturer and local mechanical code requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 3\/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\/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\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: da03rs-04\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DirectedAir","offers":[{"title":"Default Title","offer_id":51150705492274,"sku":"DA03RS-04","price":43.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305989003.jpg?v=1778616420","url":"https:\/\/voomisupply.com\/products\/directedair-da03rs-04-copper-coupling-roll-stop-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
