Engineered from 99.9% pure T2 electrolytic copper, this annealed soft copper coil delivers top-tier thermal and electrical conductivity—ideal for refrigeration lines, HVAC systems, and precision electrical components. Its fully annealed temper enables effortless bending and tight-radius routing without cracking, even in confined spaces. Precision-dimensioned at 4mm inner diameter, 6mm outer diameter, and 1mm wall thickness, it ensures consistent flow performance and seamless compatibility with standard compression fittings. Resistant to oxidation and fully workable via soldering, brazing, or flaring, this tubing excels in air conditioners, heat exchangers, generator windings, and anti-magnetic instrumentation.
