ALL fittings are offered in flanged, rolled-lip clamp together, and US Tubing airtight clamp connect ducting.
Additionally, US Duct offers the fitting in gauges from 10 - 22 gauge, and in galvanized and SS 304 and SS 316.
We offer a complete line of duct elbows to fit the application.
- From stitch welded light gauge for air/fume applications, to standard gauge segmented elbows for normal dust, to tubed elbows for airtight applications to heavy gauge welded elbow for heavy dust or heavy pressures and all the way to flat back elbows with a replaceable AR back-plate for VERY heavy chips.
- From standard single and double branches in any degree to in-cuts, to specially designed multiple branch manifolds for a special application, US Duct duct branches are rugged and degreed.
Whether you are adapting to an existing duct of any kind, to a flex hose, or to a machine equipped with metric openings, US Duct will provide you with a duct adapter fitting for the application.

Products in this collection
T-Branches
T-branches are called Ts because the line enters the main line at 90 degrees—forming a 'T'—and are often used in positive systems where the air is being pushed.
Y-Branches
Y-Branches are exactly that—Ys with the two inlets diverging from the centerline. Once again, the volume of the outlet is the sum of the two inlets.
In-Cut Branches
In-Cuts are used to create a branch on an existing trunk line.
Single and Double Branches
Single and Double Branches taper as the new line enters the mainline.
Tubed Elbows
US Duct provides duct elbows that fit EVERY application, from our standard segmented/gored elbows to one-piece light-gauge economical elbows for light dust collection to airtight elbows for wet applications.
Stitched Elbows
US Duct provides duct elbows that fit EVERY application, from our standard segmented/gored elbows and one-piece light-gauge economical elbows for light dust collection to airtight elbows for wet applications.
Segmented Elbows

Cable Hangers
Trapeze-style cable hangers, or Gripple hangers, quickly suspend duct in a hammock-like setup. Ideal for supplemental support. One hanger per 10ft of duct.
Saddle Duct Hangers
Saddle hangers, most commonly known as duct supports, are the most secure ductwork hangers available.
Hat Style Saddle Duct Hangers
The perfect blend of easy installation and stability, our hat style saddle hangers feature half-round sections of support duct to secure the main duct while a single-threaded rod (not included) offers fast-but-strong support.
Swivel Joint
Swivel joints allow for movement between flex hose and duct, or between two pieces of hard duct, but along a 360-degree stationary plane.
