US TUBING LEAK-FREE DUCTWORK

When Leaks Are Not an Option, Build With US Tubing.

US Tubing is US Duct’s premium leak-free clamp-connect industrial tubing system for applications where ordinary duct leakage can create contamination concerns, maintenance problems, performance loss, or safety risks.

Built for chemical processing, battery manufacturing, pharmaceutical production, oil mist collection, coolant mist systems, clean-process environments, and positive-pressure applications, US Tubing helps keep air, mist, vapor, and particulate moving where they belong — inside the ductwork.

With laser-welded construction, Vanstone-flanged ends, a fully encompassing gasket, and clamp-connect installation, US Tubing gives engineers, contractors, dealers, and facility teams a clean, modular, airtight ductwork solution backed by US Duct’s 100% leak-free promise.

INDUSTRIES & APPLICATIONS

Leak-Free Tubing for Demanding Industrial Environments.

Chemical Processing

Chemical facilities often require ductwork that supports corrosive fume extraction, hazardous particulate containment, and reliable process exhaust. US Tubing helps keep vapors, mist, and particulate contained inside the system while supporting cleaner, safer industrial ventilation layouts.

Battery Manufacturing

Battery manufacturing environments can require tight control of fine particulate, lithium dust, process exhaust, moisture-sensitive areas, and critical airflow performance. US Tubing supports high-performance process exhaust systems where leaks can affect safety, cleanliness, and production reliability.

Pharmaceutical Manufacturing

Pharmaceutical production environments require attention to containment, cleanability, particulate control, and contamination prevention. US Tubing supports clean-process airflow and powder handling applications where leak control matters.

Oil Mist, Coolant Mist & Positive-Pressure Systems

Oil mist, coolant mist, and positive-pressure systems expose weaknesses in ordinary duct connections. US Tubing is designed to provide liquid- and oil-mist-tight performance using a clamp-and-gasket joining system.

FREQUENTLY ASKED QUESTIONS

Have Questions About US Tubing Leak-Free Ductwork?

What makes US Tubing different from standard clamp-together ductwork?

US Tubing is designed for leak-free performance in applications where standard duct connections may not provide enough containment. It uses laser-welded tubing, Vanstone-flanged ends, a fully encompassing gasket, and a clamp-connect joining method to create an airtight seal.

What types of applications are best for US Tubing?

US Tubing is best for chemical exhaust, battery manufacturing, pharmaceutical production, clean-process systems, oil mist, coolant mist, and positive-pressure applications where leakage can create contamination, maintenance, safety, or performance concerns.

Is US Tubing only for clean environments

No. US Tubing is often used in clean-process environments, but it is also well suited for demanding industrial applications where airtight containment is required, including mist collection, process exhaust, corrosive vapor handling, and high-performance industrial ventilation.

Why is the Vanstone connection important?

The Vanstone-flanged end creates a 90-degree sealing surface around the duct end. When paired with the gasket and clamp, it helps distribute sealing pressure around the full connection instead of relying on a loose slip joint or basic friction fit. US Duct identifies this connection method as central to The Ultimate Seal®.

Can US Tubing be used in battery manufacturing facilities?

Yes. US Tubing is a strong fit for battery manufacturing environments where fine particulate, process exhaust, moisture-sensitive areas, and airflow reliability matter.

Can US Tubing be used in pharmaceutical applications?

Yes. US Tubing can support pharmaceutical and clean-process applications where contamination prevention, cleanability, particulate control, and stainless options are important. Messaging should account for GMP/cGMP considerations, hazardous powder handling, and clean manufacturing environments.
