Duct Connectors & Adapters

Duct connectors and adapters help installers, contractors, and facility teams build, modify, and route commercial ventilation ductwork. This category includes fittings for changing a duct run’s direction, adding branch connections, splitting a main line, and transitioning between different duct diameters in compatible clamp-together or quick-fit systems.

Choose fittings by the change needed in the duct layout. Elbows are available for 45-, 60-, and 90-degree directional turns, while T-branches and angled branches add paths from a main duct line. In-cut fittings are intended for adding an angled branch connection to an existing line, and reducers transition between stated duct diameters such as 6 to 5 inches or 14 to 8 inches. Confirm the required connection size at every opening, then match the fitting style to the existing system, such as clamp-together or quick-fit/QF rolled-edge connections. Also compare the listed construction details, including galvanized steel, SS construction, and available gauges.
