Description
The copper capillary tube is an essential component in refrigeration and air conditioning systems, serving as a fixed metering device that controls refrigerant flow between the condenser and evaporator. Designed for precision and consistency, this tube ensures an optimal pressure drop for stable system performance.
Manufactured from high-quality annealed copper, it allows for smooth bending and easy installation without the risk of kinking or cracking. Whether you’re servicing a refrigerator, freezer, or split AC unit, our copper capillary tube delivers long-lasting durability and efficiency.
Key Features
-
High Precision Flow Control: Maintains a steady pressure difference to regulate refrigerant flow accurately.
-
Durable Copper Material: Made from annealed copper for flexibility and corrosion resistance.
-
Easy Installation: Soft tubing allows clean bends and quick fitting in tight spaces.
-
Versatile Sizing Options: Available in multiple lengths and diameters to suit various system designs.
-
Reliable Performance: Helps prevent overfeeding or underfeeding of refrigerant for consistent cooling results.
Applications
This copper capillary tube is widely used in domestic refrigerators, commercial freezers, water coolers, and air conditioning units. It’s ideal for systems that don’t use thermostatic expansion valves, offering a simple yet effective way to maintain stable pressure and refrigerant flow.
Proper sizing and selection are crucial — choose the length and inner diameter based on system capacity and refrigerant type for the best results.
Installation & Maintenance
When installing the capillary tube, ensure both ends are clean and free of debris. Use precision cutting tools to avoid burrs and maintain smooth refrigerant flow. Always replace the filter drier when changing the tube to protect against contaminants.
