Dual-Diameter TP2 Copper Capillary Tube
Two Diameters for Graded Throttling
Our Dual-Diameter TP2 Copper Capillary Tube has two different diameters in one piece. This gives you graded throttling. It adjusts flow better for variable load systems. The transition is smooth with no steps. There is no stress concentration. It works well for heat pumps and variable frequency air conditioners. You get better energy efficiency.
High Precision for Stable Flow
This Dual-Diameter TP2 Copper Capillary Tube is made from high-purity copper. The copper content is ≥99.9%. Both sections have a tolerance of ±0.02mm. The inner wall is smooth with no burrs. Flow is stable and accurate. Our factory, Xinchang Sancai Machinery, has 15+ years of experience. We use high-precision cold drawing. Every tube is checked for size and quality.
