【Specification】Annealed UNS C12200 Copper Tubing, 1/4" (6.35mm) OD x 0.195" (4.95mm) ID, Wall Thickness 0.028" (0.7mm), Length 10 ft (3.05m), Seamless, in Coil. 【Superior Work Performance】Made of made UNS C12200 grade copper, Refrigeration copper tubing conforms to the ASTM-B280 specification. It is easy to work with, exhibits excellent thermal conductivity, corrosion resistance, and durability. It can be applied in various traditional and innovative scenarios to maximize performance and sustainability. 【Longer Lifespan】Nitrogen charged treatment for condenser copper tubes prevents oxidation, removes impurities, tests pressure, and prevents condensation, ultimately allowing copper tubing to better handle oxidation and corrosion for longer periods, thereby giving air conditioner and refrigerator a longer lifespan. 【Easy to Use】This copper tubing can be easily cut and bent accordingly with different application, the smooth and easy bending allows this copper tubing to be deformed at any angle into various shape. Moreover, this copper tubing can be easily assembled with sweating or flare fittings to build your ideas. 【Wide Application】Copper tubing is not only great for refrigerator, freezer and air conditioner as refrigeration tubing coil but also very suitalbe for 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..
