5/16" OD x 50' Copper Refrigeration Tubing, Soft Coil, Type ACR

Streamline D05050 – 5/16" OD x 50' ACR Soft Copper Refrigeration Tubing (Dehydrated, ASTM B280) Streamline D05050 is a 50-foot coil of 5/16-inch outside diameter soft copper tubing, specifically manufactured for air conditioning and refrigeration service. This product is cleaned, dehydrated, and nitrogen-purged, in accordance with ASTM B280 requirements for ACR (Air Conditioning & Refrigeration) copper tubing. Designed for systems requiring precision and internal cleanliness, the tubing is sealed with caps at both ends to prevent oxidation prior to installation. The soft temper allows for tight radius bends and minimizes the need for elbows or fittings, particularly in confined routing conditions. Technical Specifications: Tubing Type: ACR, nitrogen-charged, soft annealed Outside Diameter: 5/16 inch Wall Thickness: 0.032 inch (nominal) Length: 50 feet (coil) Material: Seamless copper, per ASTM B280 End Finish: Sealed and capped to maintain internal cleanliness Compliance: ASTM B280, UL listed, suitable for use in HVACR systems Performance Features: Factory-Dehydrated and Sealed: Helps prevent moisture contamination and oxidation during storage and transport Soft Annealed Form: Allows easy hand-bending without tools, ideal for tight clearances and intricate layouts Markings and Color Coding: Continuously incised for size/type identification; standard industry color for ACR Corrosion Resistant: Compatible with refrigerants and HVACR system oils; suitable for long-term system reliability Leak Reduction: Fewer fittings required due to flexible coil configuration Recommended Applications: Residential and commercial refrigeration line sets Split system HVAC connections Refrigerant gas and liquid line service OEM and replacement installations Installation Considerations: Tubing should be installed by HVAC professionals using industry-approved practices. Maintain nitrogen purge during brazing to avoid scale formation. Proper reaming, cleaning, and joining are essential for ensuring leak-free connections and system performance. Pressure testing after installation is recommended.
