Stainless Steel Needle Tube

What is stainless steel needle tube (hypodermic tube)?

Stainless steel needle tube, also called hypodermic tubing, is precision thin-wall tube used to manufacture medical needles, cannulas, and syringes. It is manufactured to ISO 9626 for dimensional and mechanical requirements for needle tubing.

What gauge sizes does TeCarve supply for needle tube?

TeCarve supplies stainless steel needle tube within the published product specification range: outer diameter 0.3 mm to 6 mm and wall thickness 0.1 mm to 1.0 mm. Non-standard OD and wall combinations can be reviewed against the drawing and application requirements.

What material grade is specified for hypodermic needle tubing?

ISO 9626 specifies grade 304 and 316L stainless steel for hypodermic tubing. Grade 316L is preferred for prolonged or implantable body contact due to its improved corrosion resistance and superior biocompatibility.

How is needle tube different from capillary tube?

Needle tube (hypodermic tubing) is produced to the ISO 9626 gauge system specifically for medical needle manufacturing with very thin walls and precise tolerances. Capillary tube covers a broader size range for industrial, scientific, and medical use outside the hypodermic gauge system.

What tip processing and surface treatments are available?

TeCarve supplies needle tube cut-to-length with plain, deburred, or ground-bevel ends. Custom tip geometry (bevel, lancet, back-bevel), electropolishing, and passivation per ASTM A967 are all available.
