3/8" x 3/4" x 1/2" 25' Duraguard Mini-Split Copper Line Set

Mueller® 61220250C – 5/8" OD Refrigeration-Grade Copper Tubing, 50 ft Coil Mueller® 61220250C is a 50-foot coil of refrigeration-grade copper tubing with a 5/8-inch outside diameter. Manufactured from UNS C12200 copper and cleaned using an internal nitrogen purge, it is compliant with ASTM B280 standards, ensuring suitability for high-pressure HVAC and refrigeration applications. Designed for use with refrigerants such as R-410A and R-32, this seamless copper tubing offers a working pressure rating up to 700 psi and a service temperature range up to 250°F. The tubing’s smooth internal surface supports efficient refrigerant flow and system integrity, while its corrosion-resistant properties extend service life in both residential and commercial systems. Product Specifications Outside Diameter: 5/8 inch Length: 50 feet Copper Type: Seamless UNS C12200 Internal Treatment: Nitrogen-charged for oxidation prevention Standards Compliance: ASTM B280 for ACR (Air Conditioning & Refrigeration) tubing Maximum Working Pressure: 700 psi Temperature Rating: Up to 250°F Refrigerant Compatibility: R-410A, R-32, and other high-pressure refrigerants Application & Installation This coil is intended for installation in HVAC and refrigeration systems requiring high-strength, contamination-free tubing. It is compatible with brazing or flaring connections and must be installed per applicable mechanical codes. For optimal system performance, tubing should be cut, deburred, and sealed using best practices to avoid contamination or system inefficiency.
