Bundy Tube, single-wall, double-wall, copper-brazed steel tubing, zinc-coated steel tubing
Bundy tube is made by rolling a strip of low carbon steel into a tube shape and then welding the edges together. The resulting tube has a double wall construction, with an outer layer of zinc or zinc alloy coating for corrosion resistance.
Bundy tube is known for its high strength, durability, and resistance to corrosion. It is widely used in automotive brake systems because it can withstand high pressure and provide reliable performance. The double wall construction also provides an added layer of ety in case of any leakage.
In addition to brake systems, Bundy tube is also used in other applications such as fuel lines, hydraulic systems, and refrigeration systems. It is preferred over other types of tubing due to its cost-effectiveness, ease of installation, and resistance to vibration.
Overall, Bundy tube is a versatile and reliable tubing option that is widely used in various industries, particularly in automotive applications.
