ISO9626 SUS304 Medical Stainless Steel Hypodermic Capillary Tube For Surgical Instruments
Medical capillary tubes are hollow straight hypodermic tubes that produced by stainless steel 304 material grade. SUS304 Stainless Steel exhibits excellent corrosion resistance, good formability, and high ductility, making it ideal for medical device tubing applications. Its composition - containing 18–20% Cr and 8–10.5% Ni - ensures superior biocompatibility and stability in saline or irrigating environments. Unlike TP316L, SUS304 lacks molybdenum, resulting in slightly lower resistance to chlorides but sufficient performance for short-term irrigation procedures. It maintains consistent dimensional accuracy, smooth inner/outer surfaces, and tight tolerances critical for reliable fluid delivery. Widely used in endoscopic, dental, and urological irrigation systems where cost-effectiveness and reliability are balanced.
YUHONG GROUP is professional in producing SUS304 medical capillary tubes for 30 years’ experience. The size of the capillary tubes is mainly from 0.15mm to 4mm. And the regular length for straight tubes is 2 meter maximum. These medical capillary tubes are welded by medical grade stainless steel 304 strips due to the excellent corrosion resistance.And then they’re processed through cold drawing, annealing, cleaning, cutting. If you’re interested in our capillary tubes, please contact for details.
