1/4" x 3/8" X 3/8" 50' Copper Line Set , Minisplit, Plain end

Streamline® 40680500B6 – 5/8" x 50 ft ACR Copper Refrigeration Coil, ASTM B280 The Streamline® 40680500B6 is a 50-foot soft copper coil with a 5/8-inch outer diameter, specifically manufactured for air conditioning and refrigeration (ACR) service. Fabricated from UNS C12200 copper, it is fully annealed for maximum flexibility and conformability, making it ideal for field-fabricated refrigerant line applications. Each coil is nitrogen-charged and sealed to prevent internal oxidation and maintain compliance with ASTM B280, the standard for seamless copper tube used in HVAC systems. Its plain ends allow for brazed or flared connection options, while its mechanical and thermal performance supports pressures up to 700 psi and service temperatures up to 250°F. Product Specifications Outside Diameter: 5/8 inch (0.625") Length: 50 feet coil Material: Seamless UNS C12200 copper Temper: Soft (annealed) Ends: Plain (unflared) Compliance: ASTM B280 Service Pressure: Up to 700 psi Temperature Range: Up to 250°F Condition: Nitrogen-charged, sealed ends Application Notes Designed for use with refrigerants including R-410A, R-32, and other high-pressure systems Suitable for suction or liquid lines in residential and commercial HVAC installations Annealed temper allows bending without kinking, minimizing the need for elbows or couplings Must be installed by qualified HVAC professionals using proper brazing techniques with nitrogen purge during assembly Contractor Considerations Meets job site specifications for pressure-rated, clean copper tubing Sealed-end design reduces prep time and contamination risk Backed by decades of performance in field-tested installations
