Bright Annealed Tube Stainless Steel 304 Capillary Needle Tubing for Medical Device
Stainless steel needle or hypodermic tube is a thin-walled grade designed with tight tolerances. A Stainless Steel Needle Tube are small diameter tubes that are utilized for injection under the skin. These tubes are ideal for medical applications where corrosion resistance， uniformity， and strength are of the top echelons. It is finished in accordance with customer needs regarding dimensional and wall thickness specifications as well as heat treatment for more demanding applications. In general a Stainless Steel Needle Tube is manufactured according to current standards API， ASTM， and ASME. If required for special projects we can also supply large diameter Needle Tube.
