Metal Duct Fittings
Shop galvanized metal HVAC duct fittings and round duct pipe for residential and light-commercial heating, air-conditioning, ventilation and evaporative-cooling systems. Available products include snap-lock pipe, adjustable elbows, reducers, start collars, T-wye fittings, saddle taps, dampers, end caps, register boxes, return-air boxes and flexible-duct connectors.
Use metal duct fittings to build straight runs, change direction, transition between duct sizes, create branch lines and connect ductwork to registers, grilles and HVAC equipment. Many fittings are designed for use with round galvanized pipe or insulated flexible duct.
Before ordering, confirm the duct diameter, fitting dimensions, crimped or non-crimped connection orientation and the intended airflow direction. Sheet-metal products may have sharp edges; wear appropriate gloves during handling and installation. Seal and mechanically secure duct connections according to applicable installation requirements.
