Carbon Steel Copper Coated Bundy Tube Double Walled Steel Bundyweld Tube
Bundy tube is type of double-walled low-carbon steel tube manufactured by rolling a copper-coated steel strip through 720°F and resistance brazing the overlapped seam in a process called Bundywelding. It may be zinc coated for corrosion protection. It is primarily used in automotive hydraulic brake lines in cars. We can supply any type and diameter of Bundy Tube your requirement calls for.
Bundy Tube

Common Applications
Bundy tube is famous for its use in automotive and refrigeration systems where reliability is critical:
Automotive: Brake lines and fuel lines are the most common applications. Its strength and resistance to corrosion (especially when coated or plated) make it ideal for these safety-critical systems.
Refrigeration & AC: Used for refrigerant lines in domestic refrigerators, air conditioners, and heat pumps because it is strong and can be easily bent to fit tight spaces.
Hydraulic Lines: Used in various hydraulic systems for machinery.
General Industrial Applications: Anywhere a durable, small-diameter, pressure-resistant tube is needed.
