K-Tube is the largest producer of miniature stainless steel tubing in the United States and 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.
K-Tube collaborates with device engineers and supply chain experts from idea to full-scale production, providing a single source for the entire life cycle 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.
