Hypodermic Tubing
6 Gage (0.202”-0.204”OD) to 30 Gage (0.012”-.0125”OD)
As the name implies, Hypodermic tubing is a small diameter, hard drawn needle stock. Made from type 304/304L or type 316L stainless steel, this tubing is widely used in the medical, aerospace, communication and food & beverage industries. It is also a favorite for hobbyists and model makers.
Type 304/304L stainless steel hypodermic tubing displays good corrosion resistance and can be used in air, water, oil, natural gas, and chemical circuits. Type 316L stainless steel hypodermic tubing is medical grade tubing that has a lower carbon, higher corrosion resistance than 304/304L, making it especially suited for biomedical applications.
Hypodermic tubing begins as a strip of stainless steel. It is rolled, welded, then plug drawn to its final gage size. This process gives the tubing the appearance of being seamless, as well as holding tight tolerances on both the OD and ID. It is commonly referred to as needle tubing.
Hypodermic tubing gages are based on the Birmingham Gage, also known as Stub’s Iron Wire Gage. All of our tubing is produced by using the “Tungsten Inert Gas (TIG) welded and plug (mandrel) drawn method”. A proprietary process produces smoother bore tubing compared with other commercial mills. Our hypodermic tubing is drawn to a ¾ to full hard temper (medical grade) condition, and typically has a minimum tensile strength of 150 KPSI. This condition provides excellent rigidity, strength and stiffness.
Many component parts can be made from hypodermic tubing. Some examples are spacers, nozzles, sleeves and needles.
Note: Citric passivation is available upon request.

304 S/S Hypodermic Tubing
304 S/S has a relatively low carbon content 0.08% maximum. It resists corrosion better than 302 S/S. Known for its excellent corrosion and oxidation resistance, even at high temperatures, 304 S/S has excellent cold working properties and strength which makes it an outstanding choice for fabricated parts.

316 S/S Hypodermic Tubing
316 S/S has many similar attributes of 304 S/S, but its corrosion resistance is much higher due to the addition of molybdenum. Designed for use in corrosive environments, 316 S/S has been used in many applications ranging from chemical, industrial and marine industry to medical devices.
