304 Stainless Steel Capillary Tube With OD 0.5mm-8mm And WT 0.08mm-1mm For Precision Instrumentation

SSM precision capillary stainless steel tubes are manufactured to micron-level tolerances for demanding instrumentation applications. Our cold-drawn seamless process ensures consistent bore diameter, smooth internal surface, and reliable fluid flow characteristics.

• Ultra-Fine Diameters: OD from 0.5mm to 8mm with wall thickness as thin as 0.08mm for micro-fluidic applications
• Tight Tolerances: OD tolerance down to ±0.02mm ensures precise fit in critical assemblies
• Oil-Free Internal Surface: Ultrasonic degreased and cleaned for medical, laboratory, and analytical instrument compatibility
• Flexible Supply Format: Available in precision-cut straight lengths or continuous coils up to 1000m

Essential for medical hypodermic needles, chromatography (HPLC/UHPLC) tubing, temperature sensor thermowells, pneumatic control lines, and precision dispensing systems.

100% eddy current testing for micro-defects, laser micrometer OD measurement every 50m, and borescope inspection for internal surface quality. ISO 13485 compliance available for medical-grade orders.
