micro 304 316 stainless steel capillary tube
Micro 304 & 316 Stainless Steel Capillary Tube
Baobin's stainless steel capillary tubes are precision-engineered for applications requiring high corrosion resistance, durability, and precise fluid control. These tubes are commonly used in instrumentation, medical devices, chemical processing, and aerospace applications where small diameter tubing is essential.
Our capillary tubes are available in both 304 stainless steel (for general corrosion resistance) and 316 stainless steel (for superior corrosion resistance, especially in chloride environments). We offer custom sizes and specifications to meet your specific application requirements.
Key Features
- High corrosion resistance in various environments
- Precision inner and outer diameter tolerances
- Smooth internal surface for optimal fluid flow
- Available in annealed or as-drawn condition
- Custom lengths and diameters available
- Strict quality control throughout production
