- Stainless Steel Capillary Tube
At Neeka Tubes, we manufacture and supply high-quality Stainless Steel Capillary Tubing for different industrial applications. SS capillary tubing is suitable for fluid and gas flow systems as it has a small outer diameter and a precise inner diameter. Because it is small, it can handle small amounts of samples and quickly changing temperatures. As it is very resistant to corrosion and lasts a long time, it is widely used in many industries.
Our stainless steel tubing comes in many sizes and types to meet different industry needs. The outer diameter goes from 0.1mm to 6mm. The wall thickness can be from 0.02mm to 1.5mm. Also customize the length of the tubing to fit specific needs, giving you flexibility for different uses in various industries.

Features of Stainless Steel Capillary Tubing
- High Precision: Manufactured with tight tolerances for accurate flow control. This is crucial for sensitive instruments and medical devices where exact measurements are non-negotiable.
- Corrosion Resistance: It can handle tough situations well, like chemicals and very high or low temperatures. Stainless steel’s natural properties make it long-lasting and reliable, even when it comes into contact with harsh chemicals or environments.
- Smooth Surface Finish: Reduces friction which makes it easier for fluids and gases to flow. The micro-finish also helps keep materials from depositing and blocking, which keeps performance steady over time.
- Superior Strength & Durability: Withstands high pressure and mechanical stress without deformation. This robust nature makes it suitable for demanding applications such as high-pressure liquid chromatography (HPLC) systems.
SS capillary tubing is used in many industries because it is reliable. It is used in systems for controlling liquids and gases. It is also used in medical tools and for measuring. You can find it in remote thermometer systems, small stainless steel antennas, watches, car antenna tubes and laser engraving tools. It is helpful in various instruments and analysis systems.
