At Key Gas Components, custom tube fabrication is one of our strong suits. With capabilities that include forging, forming, and bending, we supply custom tube products that exhibit an exceptionally high standard of quality. As an accomplished supplier of gas train components, we have the technical ability to manufacture products with complex specifications that require close manufacturing tolerances. Over the years, we have developed many innovative methods for tube fabrication and have invested in specialized, state-of-the-art machinery to keep quality high and unit costs competitive.

We manufacture custom corrosion, moisture, and rust-resistant tubing in round, oval, and square cross-sectional profiles with wall thickness in the .030‚ÄĚ to .180‚ÄĚ range. Burrless chamfers, serpentine shapes, and custom flange configurations are a just a few of the many design options we can accommodate. We produce sanitary tubing for potable water applications as well as structurally stable tubing that withstands high-pressure service. Materials of construction include aluminum, steel, stainless steel, copper, nickel alloys, and many others. We supply custom tube products as narrow as .125‚ÄĚ in diameter or as wide as 3.0‚ÄĚ in diameter in lengths from 3‚ÄĚ to 9‚Äô long. Bend radii are dependent on material and wall thickness and can be produced +/- 0.5¬į accuracy.

Our robust quality assurance ensures your custom fabricated tube products are dimensionally accurate, leak-tight, and conform to your specifications. We operate a fully equipped model shop for producing custom prototypes and have the production capacity to fulfill very large orders quickly and cost effectively.
