Purchase tubing direct from the source.

K-Tube Technologies is the largest producer of miniature stainless steel tubing in the United States and is the only manufacturer to offer stock and custom tubing direct from the source. After pioneering the laser-welding process, K-Tube developed a reputation for expertise, quality and innovation. Recently the company launched K-Tube Direct to ship stock and thin-walled tubing overnight to engineers and buyers in the medical device industry. K-Tube also manufactures custom and engineered tubing in a variety of alloys.

Collaborate with the experts.

K-Tube collaborates with device engineers from idea to full-scale production, providing a single source for the entire lifecycle of your device. We believe a great idea should never have to wait for tubing, so we launched K-Tube Direct to ship stock tubing to you overnight for prototyping. If stock tubing will not meet your design criteria, we offer highly customized options through our new R&D process, K-Tube Discover.

Once your project is validated and ready for volume production, you can count on K-Tube for a consistent, quality product. K-Tube's miniature stainless steel tubing is used in devices such as catheters and needles, where quality, consistency and raw material traceability is critical to a device's performance.
