Need copper tubing for an AC repair, refrigeration project, or a DIY craft? This is a 50-foot coil of soft, annealed copper tubing with a 1/4 inch outside diameter (OD). It's ACR (Air Conditioning and Refrigeration) grade, ASTM B280 standard, which means it's clean, dehydrated, and sealed - ready for refrigerant lines. Because it's soft, you can easily bend it by hand without kinking (use a tubing bender for sharp bends). Great for repairing or installing linesets for mini-splits, refrigerators, ice makers, or even for creative projects like custom water cooling loops or decorative frames. The copper is durable, corrosion-resistant, and has excellent thermal conductivity. Just cut to length, flare or solder the ends as needed. A versatile and handy material to have in the workshop.
