stainless steel capillary tube

Stainless steel capillary tubes are produced by cold drawing or cold rolling of seamless or welded mother tubes, followed by bright annealing and precision straightening. This process ensures extremely tight dimensional tolerances (±0.003 mm OD, ±0.005 mm WT) and mirror-like inner surfaces. They offer high precision, superior corrosion resistance, and smooth flow characteristics, making them ideal for instrumentation, medical devices, sensors, and microfluidic systems where reliability and cleanliness are essential. Available in grades such as 304, 304L, 316, 316L, 321, 904L, and 2205.
