Small Diameter Tubing
Most standard small diameter medical grade stainless steel tubing falls into a range of 3/8" OD (outside diameter) or less. Navigating to the hypodermic, fractional or metric charts or the master chart (a combination of all 3 charts) using the links on the bottom of the page will give you lists of standard welded and drawn stock sizes that Vita Needle carries.
The two processes that Vita uses to produce tubing (seamless and welded and drawn) each have their own strengths. When possible, Vita recommends TIG welded and drawn tubing due to the high quality, hard tempers and close tolerances that can be held. For specialty applications that require seamless stainless steel tubing (very high-pressure environments, nuclear etc), we can accommodate that as well.
Below you will find a brief comparison of the two processes. Please click on "welded and drawn tubing" or "seamless stainless tubing" links to learn more about the capabilities of each process. Or you can call us for guidance - we have hundreds of years of combined experience working with tubing and we routinely run custom tubing to specifications for customers.
