AISI304 SUS304 Cold Drawn Stainless Steel Medical Capillary Tube For Hypodermic Needle Tubing
AISI304 SUS304 Cold Drawn Stainless Steel Medical Capillary Tube For Hypodermic Needle Tubing
An ISO9626 SUS304 / AISI304 Cold Drawn Stainless Steel Medical Grade Capillary Tube is a precision-engineered, small-bore hollow tube that is manufactured to meet the stringent requirements of ISO 9626:2016 (the international standard for stainless steel needle tubing for medical devices). It is made from SUS304 / AISI304 austenitic stainless steel using a cold drawing process, ensuring exceptional dimensional accuracy, mechanical properties, and a flawless internal bore. "Medical grade" signifies that the tube is biocompatible, non-toxic, and suitable for direct or indirect contact with human tissue, blood, or medical fluids. YUHONG GROUP provides 10G-34G medical grade stainless steel capillary tubes in straight or coil length. These medical capillary tubes are welded by stainless steel 304 strips, and processed by cold drawn, annealed, straightened, cut, deburred and cleaned. Our medical stainless steel hypodermic tubes are all complied with ISO9626 standard with excellent surface finish and strict dimensional tolerance.

Different Applications of SUS304 Medical Tubes:
- Hypodermic & Biopsy Needles: The primary application (e.g., syringes, aspiration needles, spinal/epidural needles).
- Catheters & Cannulas: As a stiffener or hypotube within introducer sheaths or over-the-wire catheters.
- Endoscopy & Laparoscopy: Instruments for fluid delivery, suction, or passage of miniature tools (e.g., biopsy forceps channels).
- Dental Equipment: Irrigating tips, air/water syringe tips, and root canal files (as a handle or core).
- Medication Delivery Systems: Implantable ports, pen needles for insulin, and auto-injector components.
- Surgical Robotics: Precision tubes for fluidics or actuation cables in micro-surgical instruments.
- Microfluidics & Laboratory: Sample probes for analyzers, chromatography columns, and micro-dispensers.
- Veterinary & Research: Small animal dosing needles and micro-dialysis probes.
