This red copper tube is crafted for precise DIY plumbing, electronics, and thermal projects. It features high-purity copper with low oxygen content, delivering reliable electrical and thermal performance. Ends are cut flat and burr-free for clean fits, and the surface remains bright and easy to work with after cutting. The length you receive is a single piece, and you can trim to exact measurements for your build.

Why this copper tube stands out

• Superior conductivity: copper’s electrical and thermal performance is second only to silver among common metals, making it ideal for conductive paths and heat transfer
• Weld, braze, or solder compatibility: designed for reliable joints with standard copper fittings and flux
• Corrosion resistance and good workability: easy to form, bend, and join without compromising integrity
• Quality finish: burr-free ends and a bright, smooth surface that accepts finishes and coatings well

Practical applications

• DIY plumbing projects, micro-pipe runs for cold/hot water lines, and appliance fittings
• Electrical or thermal routing in small devices, prototyping, or hobby projects
• Cooling lines, heat transfer loops, and compact heat exchangers for experimental setups
• Custom tubing for refrigeration, HVAC tinkering, or educational demonstrations

Working tips and installation

• Use appropriate copper fittings and flux; clean ends before soldering or brazing
• Cut square with a tubing cutter or fine-toothed saw; lightly deburr for a snug fit
• Avoid kinking by bending with a proper tube bender and a generous bend radius
• Store in a dry place to minimize oxidation if not used promptly
