8 Inch to 4 Inch Round Duct Reducers provide a practical transition between duct sizes in industrial ventilation systems. Available as PVC and CPVC fittings, these reducers feature socket end connections, rugged construction, carefully inspected precision welds, and custom sizing upon request for chemical ventilation and air handling applications.


These reducers transition an 8-inch round duct connection to a 4-inch round connection within ventilation system ductwork. They can support plastic fan installations and industrial air handling systems where duct sizes change between connected components. Their PVC and CPVC construction is suited to corrosion-resistant ventilation applications involving harsh chemical environments.
