This 5-inch to 4-inch metal reducer is a high-quality HVAC component designed to transition ductwork between two different diameters. Engineered for maximum airflow efficiency, this reducer allows for a seamless connection from a 5-inch pipe down to a 4-inch pipe. Constructed from durable 26-gauge galvanized steel, it provides the structural integrity and corrosion resistance required for long-lasting performance in residential and commercial ventilation systems. It is an ideal solution for exhaust venting, kitchen range hood installations, and general air distribution where a secure, leak-resistant transition is necessary.
Type: Metal Venting Reducer
Size: 5" to 4"
Application: Used in HVAC ducting, kitchen exhaust systems, bathroom fans, and general appliance venting to connect mismatched pipe sizes.
Specifications: 26-gauge steel construction; Large End to Large End (L/E-L/E) configuration; tapered design for reduced air turbulence; compatible with standard round ductwork.
