Engineered to meet ASTM‑B280 specifications, this 100 ft coil of annealed UNS C12200 copper tubing offers exceptional thermal conductivity, corrosion resistance, and durability for refrigeration, HVAC, and DIY projects. The seamless 3/8″ OD (9.53 mm) tube with a 0.312″ ID (7.93 mm) and 1/32″ (0.8 mm) wall provides consistent flow and heat‑transfer performance across a wide range of applications.
Thanks to a nitrogen‑charged treatment, the tubing resists oxidation and maintains its structural integrity, extending the service life of air‑conditioners, freezers, and other cooling systems. The soft, flexible coil can be cut, bent, or shaped by hand or with a ratcheting tool, and it easily accepts sweating or flared fittings for quick assembly. Whether you’re building a refrigeration coil, a custom HVAC line, or a craft project, this pure‑copper tube delivers reliable results.
