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.
Straight Reducers
 |
Transition between duct of different diameters. Reducers also join larger duct with smaller duct that connects to equipment.
Spiral Duct and Fittings
 |
Reinforced with a continuous seam, this duct keeps its shape, even against suction from dust collection systems. On the inside, duct is smooth for efficient airflow. Because of its attractive look, spiral duct is often used for exposed heating and cooling systems.
Straight Reducers

Transition between duct of different diameters. Reducers also join larger duct with smaller duct that connects to equipment.
Chemical-Resistant PVC-Coated Steel—This duct combines the strength of steel with the chemical resistance of plastic. More economical than 304 stainless steel and stronger than PVC, it’s often used to exhaust corrosive gases, vapors, and fumes.

Tee Reducers
 |
Connect duct of different diameters to split or merge airflow.
Chemical-Resistant PVC-Coated Steel—This duct combines the strength of steel with the chemical resistance of plastic. More economical than 304 stainless steel and stronger than PVC, it’s often used to exhaust corrosive gases, vapors, and fumes.
45° Wye Reducers
 |
Connect duct of different diameters to split or merge airflow more gradually than tees. With less abrupt changes in direction, wyes reduce turbulence for smoother flow.
