Bundy tube, sometimes called Bundy pipe, is type of double-walled low-carbon steel tube manufactured by rolling a copper-coated steel strip through 720 degrees and resistance brazing the overlapped seam in a process called Bundywelding.

Often used with compression fittings.


We supply Metric from 6mm OD - 10mm

Tube can sometimes take 2 working days due to handling

Bundy tubing, also known as double-walled tubing or refrigerator tubing, is a type of thin-walled, double-walled steel tube commonly used in automotive and refrigeration applications to transport fluids like refrigerants, oil, and brake fluids. It offers good corrosion resistance and flexibility compared to single-walled steel tubes.

 

Key Features:

• Double-walled construction: Provides strength, leak resistance, and insulation.
• Steel material: Offers good durability and resistance to mechanical damage.
• Zinc-plated or copper-coated finish: Enhances corrosion resistance.
• Flexible: Easier to bend and route compared to rigid pipes.
• Wide range of fittings available: Enables easy connection to other components.

Applications:

• Automotive: Braking systems, fuel lines, power steering systems, air conditioning systems, oil cooler lines.
• Refrigeration: Refrigerant lines, compressor connections, condensers, evaporators.
• Industrial: Pneumatic systems, lubrication lines, instrument gauges, vacuum system
