Imperial Manufacturing GV0808A Furnace Pipe Reducer 4 in. x 3 in. 24 Ga Small End Crimped Galvanized

size: 4in

Imperial Manufacturing GV0808A furnace pipe reducer connects 4 in. ducting to 3 in. openings. The 24-gauge galvanized steel body resists corrosion in heating and ventilation runs.

Suitable for gas furnaces, water heaters and general HVAC exhaust routing.
