Engineered for Precision and Performance

Our copper capillary tubes are crafted to exact tolerances (0.05 mm) using high-purity copper. These tubes support precision control, reliability, and safety in sensitive applications, including medical and instrumentation installations. With customizable sizes and lengths, our tubing adapts seamlessly to a wide range of specific project needs.

Versatile Application Range

Suitable for refrigeration, air conditioning, medical, and industrial systems, our capillary tubing is tested for high pressure and temperature conditions. Its superior corrosion resistance and polished surfaces ensure long-term durability and reduced system maintenance. Custom connection types and finishes are also available to meet unique installation situations.

FAQs of Copper Capillary Tubing:

Q: How can I select the right copper capillary tube size and specification for my application?

A: To choose the appropriate tube, consider the intended application (e.g., refrigeration or medical gas line), required diameter and thickness, working temperature, pressure demands, and preferred length. Our tubes come in inner diameters from 0.5 mm to 4 mm and standard outer diameters of 1.5 mm to 6 mm, with customizable lengths and coil sizes to fit your needs.

Q: What are the primary uses of copper capillary tubing in industry?

A: Copper capillary tubing is commonly used in refrigeration, air conditioning, instrumentation, and medical gas lines. Its excellent conductivity, corrosion resistance, and precision tolerances make it ideal for situations requiring accurate fluid transfer and long lifespan.

Q: When should I use coil packing versus straight lengths or spools?

A: Coil packing (15 m or 30 m standard coils) is preferred for installations that require flexibility and longer continuous runs. Straight lengths suit structured installations or where precise, measured sections are needed. Spool packing is useful for automated or large-scale manufacturing. Custom packing options are also available upon request.

Q: Where are these copper tubes manufactured and exported from?

A: Our copper capillary tubing is manufactured and supplied from India, adhering to international quality standards. We serve as exporter, manufacturer, and supplier for global markets, supporting multiple industry requirements.

Q: What is the benefit of the high conductivity (>99.9% IACS) in this tubing?

A: The high electrical and thermal conductivity of our copper tubes ensures efficient energy transfer, minimizes losses, and optimizes system performanceespecially important in refrigeration, instrumentation, and HVAC systems.

Q: How does the minimum bending radius affect installation?

A: A minimum bending radius of 3x the outer diameter allows for easier routing in tight spaces without compromising the tubes integrity, reducing the risk of kinking and enhancing flexibility during installation.
