Stainless Steel Capillary Tube , SUS304 SUS316 , Bright Annealed Tube For Precision Application
Stainless steel capillary tubes are made from stainless steel grades like 304, 316 grade, known for good corrosion resistance, durability, and high-temperature tolerance. They are thin-walled, small-diameter tubes (typically 0.5 mm to 10 mm), which are designed for precision fluid or gas transfer. These tubes are generally cold drawn from stainless steel strips to achieve precise dimensions and smooth interiors. Stainless steel capillary tubes are vital in industries requiring precise, reliable, and durable fluid handling. Their good resistance to corrosion and high pressures, coupled with precise manufacturing, makes them indispensable in medical, industrial, and automotive applications.
Our Group is professional in producing stainless steel bright annealed capillary tubes in straight or coiled type. We can provide custom-made capillary tubes for clients according to their requirements. All of our capillary tubes have smooth surface and tight size tolerance, which are widely used for applications, such as aerospace industry, precision instruments, medical devices(e.g. needle, catheter, syringe), auto parts, clothing industry and so on.

Key Applications Of Stainless Steel Capillary Tubes:
Frequently Asked Questions:
1.What grades of stainless steel are commonly used?
The most common grades are 304 (general-purpose) and 316/316L (superior corrosion resistance, especially in chloride environments). Other grades like 321 or 430 may be used for specific needs.
2.What standards/certifications apply?
-Medical: ISO9626: 2016
-Industrial: ASTM A269 / 213
3.What sizes and dimensions are available?
-Diameter: 0.5mm to 10mm or as required
-Wall Thickness: 0.1mm to 2mm.
-Length: Customizable based on application requirements.
4.How are they cut or shaped?
Use fine-tooth saws or precision tube cutters. Deburr edges to prevent contamination. For bending, specialized bending machine or annealing (heating to reduce brittleness) is required to avoid kinking.
