Hypodermic Tubing Information and Gauge Chart

New England Small Tube provides custom and stock hypodermic tubing commonly used in medical, industrial, and scientific applications. Hypodermic tubing is a type of small-diameter, thin-walled tubing. It is often made from 304 or 316 stainless steel due to its durability, corrosion resistance, and ability to be sterilized.

Standard hypodermic tubing is most commonly welded and plug drawn for a smooth and consistent ID finish throughout. Tolerances are typically held tighter than other draw types and more economical due to the ease of manufacturing.

NEST Hypodermic Tubing has many benefits including:

  • High strength-to-weight ratio.
  • Resistant to bending or deformation.
  • Biocompatible (for medical-grade materials).
  • Resistant to heat and chemicals.

Hypodermic Tubing For A Variety of Applications

Our hypodermic tubing is used in many applications including hypodermic needles for injections, fluid withdrawal, or biopsy procedures. Other uses include precision dispensing of liquids or gases and probes or small-scale fluid transfer systems along with laboratory instruments and microfluidic systems.

Custom and Stock Hypodermic Tubing
