Ray's Dies & Tubing is a specialized manufacturer and supplier of hypotube and hypodermic tubing in 304 and 316L stainless steel. We stock and fabricate thin wall stainless steel tubing in an extensive range of OD and ID combinations — from sub-0.010" micro-bore sizes to standard hypodermic gauges — for medical device, catheter, guidewire, and industrial applications.
As a long-established stainless steel tubing manufacturer, we maintain a deep inventory of ready-to-ship stock and offer custom cut-to-length and finishing services with short lead times.
Stock in both grades — 316L for medical-grade, implantable, and fluid-contact use.
Sub-0.010" OD sizes up to standard hypodermic gauges with tight OD/ID tolerances, held with our in-house centerless grinding capability.
Cut, deburred, and finished to spec via our custom cutting services. Short-run and production quantities welcome.
Catheter shafts, guidewires, biopsy needles, endoscopic tools, and surgical instruments, often finished with our EDM services for complex geometries.
Hypodermic needles and micro-channel assemblies requiring precise ID flow characteristics.
Probe housings, thermocouple sheaths, hydraulic lines, and precision mechanical assemblies, supported by our CNC machining services.
