Stainless Steel Capillary Tubing

Stainless steel capillary tubing is widely used in applications requiring high precision, small diameters, and reliable performance under demanding conditions. Compared with standard tubing, capillary tubes are characterized by their tight dimensional tolerances, smooth surface finish, and consistent mechanical properties.

Our stainless steel capillary tubing is manufactured using advanced cold drawing and precision processing techniques to ensure accurate outer diameter, inner diameter, and wall thickness control. This makes it suitable for critical applications where flow control, pressure resistance, and cleanliness are essential.

We offer a wide range of materials, including 304, 316, and 316L stainless steel, ensuring excellent corrosion resistance in various environments. The tubing can be supplied in straight lengths or coils depending on customer requirements, with customizable dimensions to meet specific project needs.

In industries such as oil & gas, capillary tubing is commonly used for chemical injection lines, instrumentation systems, and downhole applications. In medical and laboratory environments, it is used where precision fluid control is required. Its versatility and reliability make it an essential component across multiple industries.
