Soft copper tubing PVC coated used in HVAC and gas applications

Soft Copper Tubing PVC Coated for Flexible Industrial Applications

Soft copper tubing PVC coated is widely used in HVAC, refrigeration, gas and instrumentation systems where flexibility, corrosion resistance and protection are essential. The soft (annealed) copper allows easy bending and installation, while the PVC coating provides protection against environmental factors.

These tubes are ideal for applications requiring long continuous runs with minimal joints, ensuring efficient and leak-free performance.

What is Soft Copper Tubing PVC Coated?

Soft copper tubing PVC coated refers to annealed copper tubing externally coated with polyvinyl chloride (PVC). The annealed copper provides flexibility, while the PVC coating protects against corrosion, moisture and mechanical damage.

These tubes are typically supplied in coil form for ease of handling and installation.

Why Use Soft Copper Tubing PVC Coated?

In many industrial and residential systems, flexibility and protection are required simultaneously. Soft copper tubing PVC coated provides both, making it suitable for complex routing and harsh environments.

Key Advantages of Soft Copper Tubing PVC Coated

  • High flexibility for easy bending and installation
  • Excellent corrosion resistance
  • Protection against moisture and environmental exposure
  • Reduced number of joints and leak points
  • Long service life with minimal maintenance

Copper Grades Used in Soft Copper Tubing

These tubes are typically manufactured from:

  • C12200 – Phosphorus-deoxidized copper

This grade ensures excellent durability and performance in various applications.

Standards Applicable to Soft Copper Tubing PVC Coated

The tubing generally complies with the following standards:

  • ASTM B280 – Copper tubing for HVAC and refrigeration
  • ASTM B68 – Seamless copper tube
  • EN 12735 – Copper tubes for refrigeration
