US Tubing® by US Duct is a liquid-tight, oil mist-tight clamp-together ductwork system used in battery manufacturing plants, wastewater treatment facilities, and automotive manufacturing.
Leaks happen. But they don’t have to.
US Tubing® is US Duct’s liquid-tight, oil mist-tight clamp-together duct system, built for industrial environments where leaks are more than an inconvenience. They’re a risk. Battery plants, wastewater treatment facilities, and automotive manufacturers rely on US Tubing when ductwork has to seal tight and stay that way.
We call it The Ultimate Seal® because once it’s clamped, it stays sealed.


Loose joints, mist escaping, corrosion starting where it shouldn’t—we’ve seen it all. US Tubing was designed to solve the problem at the connection point, where leaks usually start.
No guessing. No sealant tricks. Just a tight joint every time.
Battery manufacturing environments demand ductwork that holds up under corrosive vapors, oil mist, and strict safety standards. A small leak can turn into a big problem fast.
The liquid-tight seal helps protect people, equipment, and the process itself—exactly what battery plants need.


Wastewater plants are hard on ductwork. Moisture, condensation, corrosive gases, and odor control all push systems to their limits.
US Tubing is built for it.
The clamp-together design makes installation and maintenance easier in tight plant spaces, while the seal keeps leaks and corrosion in check.
Automotive manufacturing is full of oil mist, coolants, and metalworking fluids. If ductwork leaks, that mist ends up where it doesn’t belong.
When production lines change, the modular design allows fast reconfiguration without compromising the seal.

Every US Tubing component features a Vanstone-flanged end, formed by turning the pipe edge 90 degrees. A V-shaped gasket is applied directly over that edge.
When the clamp is tightened with a torque-tightening bolt, the gasket is compressed evenly around the entire circumference of the joint.
You get the sealing performance of flanged ductwork with the speed and flexibility of a clamp-together system.

Everyone does. The difference is knowing how to handle them.
Leaky ductwork affects safety, efficiency, and air quality—but it’s preventable. Our guide walks through the most common causes of duct leaks and what to look for when choosing a secure connection.
US Tubing is a strong choice for battery plants because it provides a liquid-tight, oil mist-tight seal that holds up in corrosive and safety-critical environments.
Clamp-together liquid-tight ductwork like US Tubing performs well in wastewater plants by resisting moisture, corrosion, and odor leaks.
Yes. US Tubing is designed specifically for oil mist collection in automotive machining and metalworking operations.
Leaks are prevented by a fully encompassing V-gasket applied directly to a Vanstone-flanged pipe end, uniformly compressed by a clamp.
