1/4" OD x 50' Copper Refrigeration Tubing, Soft Coil, Type ACR

Streamline D04050 – 1/4" OD x 50' Soft Copper Refrigeration Tubing, ASTM B280 Rated Streamline D04050 copper refrigeration tubing is designed for HVACR applications requiring consistent performance, flexibility, and compliance with critical system standards. Manufactured from high-grade copper and furnished in a 50-foot coil, this 1/4" outside diameter tubing is fully dehydrated and nitrogen-purged to eliminate internal moisture prior to system charging. This soft-annealed tubing conforms to ASTM B280 requirements and is rated for up to 700 psi working pressure, making it suitable for use in air conditioning and refrigeration lines carrying refrigerants such as R-410A and R-22. Product Specifications: Material: Seamless copper Outside Diameter: 1/4 inch Wall Thickness: Nominal per ASTM B280 (varies by manufacturer batch) Length: 50 feet Temper: Soft annealed (bendable) Working Pressure: 700 psi Standard Compliance: ASTM B280, UL Listed Packaging: Coiled, nitrogen-charged, sealed ends Key Features: ASTM B280 Compliance – Meets the mechanical and cleanliness specifications required for refrigerant line sets 700 psi Pressure Rating – Supports high-pressure refrigerants, including R-410A systems Soft Annealed Coil – Facilitates on-site bending and routing without kinking Cleaned and Sealed – Each coil is internally cleaned, dehydrated, and charged with nitrogen to maintain system cleanliness Flexible Application – Commonly used for suction and liquid lines in split-system air conditioners, heat pumps, and refrigeration systems Typical Applications: Residential and light commercial air conditioning Refrigeration equipment installations Replacement or extension of refrigerant line sets Compressor connections and service lines Installation Considerations: Tubing should be cut with a proper tubing cutter and deburred before flaring or brazing. When brazing, purge with dry nitrogen to prevent internal scaling. Ensure compatibility with refrigerants and that connections are leak-tested before system startup. For best results and to meet code requirements, installation should be performed by a licensed HVAC technician.
