Leak-Free Tubing

When a single leak isn't an option, this is the answer. US Tubing is our premium airtight ductwork — laser-welded and clamp-connect, backed by a 100% leak-free guarantee for oil mist, coolant mist, and positive-pressure applications.

US Tubing is US Duct's premium airtight ductwork, engineered specifically for leak-free performance in demanding industrial environments. This modular, clamp-connect system combines laser-welded construction with the sealing performance of flanged duct and the installation speed of clamp-together duct — built for oil mist, coolant mist, and positive-pressure applications where any leak is a problem. Backed by the Ultimate Seal 100% leak-free guarantee, US Tubing gives engineers and plant managers the airtight, oil-tight, and pressure-positive performance their processes demand, without the install time of traditional welded systems.
