Copper and Copper Nickel Coils

Automec supply top quality thick-walled (0.9mm 20swg) Copper and Copper Nickel coils, conforming to BS2871 Part 3, C106/ CN102. Batch tested for tensile strength, burst pressure and cleanliness to BLS.30.JC.101. Each coil is marked for traceability and is available in all diameters from 1/8" to 1/2" od. (and metric equivalents).

COPPER BRAKE TUBE Recommended Max. Working Theoretical Burst Pressure
