Refrigerator Copper Line Tube and Fittings
Our refrigerator copper line tube is an essential component in modern cooling systems, ensuring efficient and reliable refrigerant circulation. Manufactured from high-purity copper (≥99.9%), this copper refrigeration tube delivers excellent thermal conductivity, corrosion resistance, and long-term durability. It is widely used in household refrigerators, freezers, and display coolers.
With a smooth inner wall and precise dimensions, our copper tube for refrigeration reduces flow resistance and enhances energy efficiency. Both soft (annealed) and hard temper types are available, suitable for flaring, welding, and bending processes. Whether for OEM manufacturing or HVAC system maintenance, our copper tubing supports secure, leak-free connections.
Common Types of Copper Refrigeration Tubes
Our copper refrigeration tubing is available in multiple types depending on its role in the system:
Capillary Tube: Used for metering refrigerant between the condenser and evaporator.
Suction Line: Carries low-pressure vapor refrigerant from evaporator to compressor.
Discharge Line: Transports high-temperature refrigerant vapor from the compressor to the condenser.
Liquid Line: Carries condensed refrigerant to the expansion device or evaporator.
These tubes meet standard copper pipe sizes for HVAC applications and are compatible with common system layouts.
Standard Refrigeration Copper Tube Sizes
| Outer Diameter (mm) | Outer Diameter (inch) | Wall Thickness (mm) | Typical Use |
