Product Description
High-Precision C11000/T2 Pure Copper Capillary Tubes
Our C11000/T2 Pure Copper Capillary Tubes are precision-engineered for critical flow control in refrigeration and air conditioning systems. Made from 99.99% pure copper (C11000/T2/C1100/ECU-58), these tubes serve as efficient restrictors for refrigerant flow and pressure regulation. Available in hard, soft, or half-hard tempers, they ensure reliable performance in demanding environments. With customizable dimensions and international certification (ASTM B280, EN 12735-1, JIS H3300), our capillary tubes meet global engineering standards.

Working Principle
Pressure Reduction: High-pressure liquid refrigerant from the condenser enters the narrow capillary tube. The small internal diameter (typically 0.4–3mm) creates a pressure drop, reducing the refrigerant to low-pressure, low-temperature liquid.
Flow Control: The tube's length and inner diameter are calibrated to match compressor capacity and system load, maintaining stable evaporator pressure.
Evaporator Feed: The cooled refrigerant expands into the evaporator, absorbing heat from the surrounding environment.
System Advantages:
– No moving parts → low maintenance
– Cost-effective compared to expansion valves
– Ideal for small to medium hermetic systems (up to 30kW)

Frequently Asked Questions
Q1: What is the difference between C11000 and T2 copper?
A: C11000 (UNS) and T2 (GB) are both electrolytic pure copper grades with ≥99.90% copper content. They are equivalent in performance and widely used in capillary tubes.
Q2: Can you customize the inner diameter (ID) and length?
A: Yes. We produce tubes with IDs from 0.4mm to 3mm and lengths up to 12 meters. Custom coil weights (5–50kg) are also available.
Q3: Are your tubes compatible with R410a refrigerant?
A: Absolutely. Our capillary tubes are cleaned and processed to be compatible with R410a, R134a, R407a, and hydrocarbons.
Q4: What is the delivery time for 500kg orders?
A: Standard delivery is 5–7 working days for orders up to 2 tons. Larger volumes may require 7–10 days.
Q5: How are the tubes packaged for export?
A: We use seaworthy wooden cases with end caps and foam protection. Coils are packed in cartons to prevent deformation during shipping.
Q6: Do you provide samples?
A: Yes, free samples are available for qualified buyers. Contact us with your specifications.
