Copper Refrigeration Tubing for HVAC

This 9.8 ft length of soft coil copper tubing has a 5/64 inch outer diameter and 3/64 inch inner diameter. It is designed for heat exchange in refrigerators, freezers and air conditioners. The material also serves as an automobile oil pipe.

Practical Limits of Soft Copper Tubing

The 0.5 mm wall thickness and 2.5 mm outer diameter restrict this tube to low-pressure refrigerant lines and small-bore oil circuits. It cannot handle high-pressure hydraulic systems or large-capacity cooling loops. Bending radius is limited by the thin wall to avoid kinking.

Installation Notes and Common Issues

The coil cuts easily with a standard tubing cutter and bends by hand for tight routing. Flare or compression fittings must match the 5/64 inch OD precisely or leaks will occur. Over-tightening crushes the thin wall and annealing is required for complex shapes.

Questions about this item

How do I choose between the 5/64" OD and 3/64" ID specifications for my refrigeration project?

The tubing has a 5/64" outer diameter and 3/64" inner diameter, providing a 0.5mm wall thickness. Select based on your system's fitting size and required flow capacity for refrigerant or oil lines.

What does the 9.8 Ft length mean when installing this copper tubing in an air conditioning system?

The 9.8 Ft (3 meter) coil provides enough straight length for typical residential AC refrigerant runs. The soft copper allows bending without kinking, reducing the need for extra fittings during installation.

How does the 5/64" OD interface with standard flare fittings in automotive oil pipe applications?

The 5/64" outer diameter matches common miniature flare fitting sizes used in automotive oil lines. The soft copper tubing seals reliably when flared, and its corrosion resistance suits long-term under-hood exposure.
