【Dimension】: 1/2" OD x 0.445" ID (11.303mm); Length: 50ft (15.24m); Wall thinkness: 0.028" (0.7mm); Seamless, in Coil. 【Superior Performance】: Refrigeration copper tubing is made of Annealed UNS C12200 grade copper and conforms to the ASTM-B280 specification. It has exhibits excellent thermal conductivity, durability and corrosion resistance. In various innovative scenarios, it can maximize performance and sustainability. 【High Quality】: It can achieve longer lifespan of air conditioning and refrigeration because of the nitrogen charged treatment. For the copper tube, it can prevents oxidation, removes impurities, tests pressure, and prevents condensation, ultimately allowing copper tubing to better handle oxidation and corrosion for longer periods. 【Easy to Use】: This copper tubing can be cut and bent according to the different need, and the smooth bending allows the copper tube to be deformed at any angle for various shape. In addition, this copper tubing can be easily assembled with sweating or flare fittings. 【Wide Application】: Copper tubing is not only used in refrigerator, freezer and air conditioner as refrigeration tubing coil, but also used as a HVAC system pipe or ACR tubing. It is also widely used for electrical, thermal conductivity, industry, DIY projects, jewelry handicrafts, architectural models, architectural decoration, crafts, etc..
