Precision Throttling Straight Copper Capillary Tube
Accurate Flow Control for Better Efficiency
Our Precision Throttling Straight Copper Capillary Tube is made for exact refrigerant metering. The inner diameter is very consistent. This gives you stable pressure drops. Your system runs more efficiently. It avoids high energy use or poor cooling. The flow consistency is within ±3%. This tube is perfect for air conditioners, dehumidifiers, and chillers.
Smooth Inner Wall Reduces Resistance
This Precision Throttling Straight Copper Capillary Tube has a smooth inner wall. There are no burrs or oxide layers. Refrigerant flows easily. This lowers noise and improves performance. We use high-precision cold drawing. The tolerance is ±0.02mm. Our factory, Xinchang Sancai Machinery, has 15+ years of experience. We test every tube for size and straightness.
