Our 304 & 316L Stainless Steel Capillary Tubes are precision-engineered for applications requiring high corrosion resistance, excellent hygiene, and reliable performance in demanding environments. These small-diameter tubes are ideal for medical devices, instrumentation, aerospace, and precision mechanical assemblies. We offer comprehensive processing customization, including precision laser cutting to length, creating tapered ends for easy insertion, and complex flange bending to meet specific design requirements. Our capabilities allow for the transformation of raw tubing into finished, ready-to-install components.
Grade 304 Stainless Steel: A versatile chromium-nickel austenitic steel offering excellent corrosion resistance, good formability, and weldability. Suitable for a wide range of environments, particularly those involving organic chemicals and mild corrosives.
Grade 316L Stainless Steel: The low-carbon version of 316, providing superior corrosion resistance, especially against chlorides and acids. Its enhanced biocompatibility makes it the preferred choice for medical, marine, and highly corrosive industrial applications.
The following table outlines the standard technical parameters for our stainless steel capillary tubes.

Our processing customization services transform standard tubing into complex components. Key services include:
Precision Laser Cutting: Clean, burr-free cutting to exact lengths with high repeatability. Perfect for creating multiple, identical parts from longer tubes.
End Forming - Tapered End: Forming a tapered or pointed end on the tube for applications requiring easy insertion, such as hypodermic needles or fluidic connectors.
Flange Bending & Forming: Creating precise flanges, collars, or other complex shapes at the end of the tube to serve as connection points or mounting surfaces.
Other Value-Added Services: Bending, coiling, welding, polishing, and deburring to meet your complete component specifications.
We work with you from prototype to production, ensuring the final part meets your exact design and functional needs.
