Airtight Quick-Connect Ductwork by US Tubing

AIRTIGHT, LEAK FREE CLAMP CONNECTION PRODUCT IS THE ULTIMATE SEAL®!

US Tubing US Duct's airtight Clamp-Connect system is a modular, laser welded, clamp-and-gasket joining system that is guaranteed to be leak-free.

Each component terminates in a turned out lip on each end. A v-shaped gasket fits over one lip at each joint and then the connection is completed using an adjustable clamp. When the clamp is tightened, it compresses the gasket between the pipe edges to form an airtight seal.

The components (pipe, branches, elbows, etc.) are standard 16 gauge metal (galvanized, stainless steel, painted) with a range of 22 to 16 gauge available upon request. The pipe comes in standard 59” lengths which can be easily clamp-connected together to produce long runs. An adjustable sleeve pipe allows for easy adjustments in the field.

What Makes US Tubing Airtight

Clamp-Connect Gaskets

The real difference is the leak-free, airtight torque-tighten clamp and full gasket system — creating the Ultimate Seal®! The end of all components is turned back at 90 degrees to the pipe (think very precise Vanstone). Unlike rolled lip duct where the gasket is in the clamp or even applied to the face of the lip, the US Tubing v-shaped gasket encompasses the entire end! A high strength, torque-tightened clamp then surrounds the pipe and gasket and compresses the pipe together on the gasket, ensuring a leak-free system!

The contoured gasket is specifically manufactured to create an airtight seal between the two Vanstone ends of the tube and accessories. The gasket fits snuggly over one of the Vanstone ends at each joint to provide the amazingly tight seal of the US Tubing Clamp-Connect System. Depending on your application, you can select just the right gasket and o-ring to seal your duct. Choose from:

  • EDPM Conductive for special applications that require conductivity for grounding purposes
  • Silicone for corrosive and high-temperature applications 
  • EDPM Standard Seal for dust collection, non-corrosive and mist applications

Leak-Free Clamps

Unlike rolled lip duct where the gasket is in the clamp or even applied to the face of the lip, the US Tubing v-shaped gasket encompasses the entire end! A high strength, stainless steel channel clamp with a torque-tighten bolt and over-center clamp then surrounds the pipe and gasket and compresses the pipe together on the gasket, ensuring a leak-free system. Each handle is equipped with a safety latch to ensure against accidental release.

Grounding bridge/brackets, welded to the clamp, are available for added conductivity assurance. Our grounding bracket is spot-welded to the clamp and holds two spring-loaded bolts against the metal surface of the duct to provide excellent conductivity throughout the system. NOTE: No tools or extra time needed for installation as the grounding bridge comes welded to the clamp.

The contoured gasket is specifically manufactured to create an airtight seal between the two Vanstone ends of the tube and accessories. The standard gasket is EDPM-Conductive for corrosive resistance and grounding purposes. The gasket fits snuggly over one of the Vanstone ends at each joint which, when compressed by our custom clamp, creates the amazingly tight seal of the US Tubing Clamp-Connect System.

Modular Tubing System with Infinite Adjustability

The adjustable sleeve* is available to allow for infinite adjustments in the field where less than 5' of duct is required. Both ends of the pipe have Vanstone edges and a diameter sized slightly larger than the connecting component to allow for adjustment by sliding the pipe. Once the pipe has been measured and cut to the correct length, the sleeve slides over the cut end of the pipe and is secured via an O-ring and clamp to seal the connection. Multiple gaskets are available depending on your application requirements. High temperature, food-grade, and corrosive resistant gasket options are available.

*Use of the sleeve may affect the ratings and allowances for certain applications, especially where FDA requirements are applicable.
