Manufactured from C12200 copper and conforming to ASTM B280, this tube is pressurized with nitrogen to inhibit internal oxide formation during brazing operations. Reducing oxide buildup lowers the risk of system contamination in refrigerant circuits. The tube measures 3\/4 inch OD at 20 feet in length and weighs 0.362 pounds. Licensed HVACR technicians and refrigeration mechanics rely on ACR-grade tube for its cleanliness, dimensional precision, and material strength under operating conditions.\u003c\/p\u003e\n\u003cp\u003eThis tube is suited for residential and light commercial HVAC installations, refrigeration equipment, and split-system applications where clean, oxide-free refrigerant lines are required. The nitrogenized interior is particularly beneficial in systems using modern refrigerants where even minor contamination can degrade compressor performance or damage TXV components. It is appropriate for new installations and service replacement work where ACR-grade material is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNitrogenized interior suppresses oxide formation during brazing, reducing contamination risk in refrigerant circuits\u003c\/li\u003e\n  \u003cli\u003eManufactured from C12200 copper for consistent purity and formability\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM B280 and UNS C12200 standards for ACR copper tube\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch OD x 20-foot length suits common residential and light commercial line set applications\u003c\/li\u003e\n  \u003cli\u003ePrecision dimensions support consistent fitment with standard ACR fittings and swage connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style ACR copper tube for use in residential and commercial HVAC and refrigeration systems where ASTM B280-compliant, nitrogenized copper tube is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVACR technician. Ensure the refrigerant system is fully recovered and de-pressurized before cutting or brazing any existing lines. Use appropriate brazing alloy and maintain nitrogen purge flow through the tube during brazing to preserve the clean interior. Work should comply with applicable mechanical codes and local jurisdiction requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: ACR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: C12200 Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASTM B280, UNS C12200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 20 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.362 pounds\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 INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ac05020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER INDUSTRIES","offers":[{"title":"Default Title","offer_id":51268290478386,"sku":"AC05020","price":217.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308909191.jpg?v=1780702728","url":"https:\/\/voomisupply.com\/products\/mueller-industries-ac05020-acr-copper-tube-3-4-in-od-20-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
