Capillary Tube also known as ultra-thin tube or medical tubing. These Stainless Steel Capillary Tube and Hypodermic Tubing are produced between 0.1 – 8 mm which can sustain in high temperature and corrosive environments. Precision Stainless Steel Tubing are used in various applications such as Medical and Pharmaceutical, Aerospace, Chemical Processing, and Instrumentation.

Stainless Steel Hypodermic Tubing comes in all gauges including Thin Wall (TW) and Regular Wall (RW). Welded and drawn Stainless Steel Hypodermic Tubing are known for tight OD and ID tolerances as per ASTM A908 standard. Capillary Tubing standard sizes are 3 to 33 gauge. These SS Capillary Tube can be manufactured in various grades such as T201, T304, T304L, T316, T316L, T410, T465, and 17-7. Among them 316 and 304 Stainless Steel Capillary Tube are the most selling grades.

Manufacturers of Capillary Tube prefer cold drawing methods to ensure high dimensional accuracy and smooth surface. SS 304 Capillary Tubing can be bent without cracking for Medical Devices. Victor Steel is a leading Stainless Steel Capillary Tube Manufacturer in India, specializes in producing high-quality 304 and 316 micro tube suitable for chemical injection and HPLC systems.
