    Standard Duct and Fittings

    Image of System. Front orientation. Exploded view. Duct and Fittings. 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.

    Change the direction of airflow when joining lengths of duct.
    Galvanized Steel—Corrosion resistant and affordable, galvanized steel is the most commonly used ductwork material.
    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.
    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.

    Quick-Disconnect Duct and Fittings

    Image of System. Front orientation. Exploded view. Duct and Fittings. Quick-Disconnect Duct and Fittings.
    The fastest ductwork to disassemble for dust collection and other frequently cleaned systems. Join sections with quick-release clamps that open and close with a flip of the latch. Since you don’t need screws, welds, or tools, the installation time is half that of other duct types.
    Adjustment Sleeves
    Image of Product. Front orientation. Duct and Fittings. Quick-Disconnect Duct and Fittings, Adjustment Sleeves.
    Close gaps between sections of duct without disassembling the whole line. To install these sleeves, cut the end of your duct and place the O-ring on the cut piece. Then, slide the sleeve on and clamp in place.
    Galvanized Steel—Corrosion resistant and affordable, galvanized steel is the most commonly used ductwork material.
