Standard Duct and Fittings

Deliver air for a range of HVAC applications, including exhaust and dust collection. Our basic duct, the round shape creates smoother, more efficient airflow than rectangular and oval duct. The male end is slightly smaller than the female, so sections join without clamps or tools.

Duct

Closed Duct

Pair with compatible fittings and accessories.

Corrosion-Resistant 304 Stainless Steel—The most corrosion-resistant metal duct we sell. It won’t rust or degrade in systems that exhaust chemical fumes or vent heat from industrial ovens and dryers.

Closed Duct—With a closed seam, this duct is stronger and less prone to air leaks than open duct. However, it’s not as quick to modify when installing.

Galvanized Steel—Corrosion resistant and affordable, galvanized steel is the most commonly used ductwork material.

Lightweight Aluminum—One-third the weight of steel, aluminum ductwork is easier to handle during installation. Like galvanized steel, it resists rust in wet environments but won’t last as long.

Duct Blast Gates

Open and close the slide to control airflow to sections of duct. Blast gates turn flow on or off.

Aluminum with Galvanized Steel Slide—The body is aluminum to reduce stress on your duct and the slide is galvanized steel for strength. Both components resist rust in wet environments.

Corrosion-Resistant 304 Stainless Steel—The most corrosion-resistant metal duct we sell outperforms aluminum in harsh environments. It won’t rust or degrade in systems that exhaust chemical fumes or vent heat from industrial ovens and dryers.

Chemical-Resistant Duct and Fittings

Chemicals can eat away at most metal duct, but not this PVC system. It’s often used to exhaust corrosive gases, vapors, and fumes. Components press-fit together and secure with PVC pipe cement.

Duct

Pair with compatible fittings and accessories.

To start a run of duct, mount a flange to equipment. Flanges also create a secure joint between sections of duct—attach a flange to each piece. Also known as angle rings.

Tight-Seal Spiral Duct and Fittings

Gasketed fittings prevent leaks between connections without the need for tape or other sealants. Duct has a continuous seam that reinforces it for strength and long life. The rigid construction keeps its shape, even against suction from dust collectors. Duct is smooth on the inside for efficient airflow. Because of its attractive look, spiral duct is often used for exposed heating and cooling systems.

Straight Collars

Link rectangular duct systems to equipment that uses round duct. Cut a hole, install the collar, and connect a piece of round duct.

Galvanized Steel—Corrosion resistant and affordable, galvanized steel is the most commonly used ductwork material.

Polyethylene Foam Gasket—The flange has an adhesive-backed gasket to bond the connection until you fasten with screws. The gasket also prevents leaks.
