This 150/120 mm flue reducer is used to safely change the diameter of heavy-gauge flue pipes between the appliance and the chimney. High-quality steel with a 1.5 mm wall thickness ensures excellent resistance to heat and mechanical stress, while the black finish matches standard flue pipes and modern boiler rooms or fireplace interiors.
Thanks to its 80 mm length, installation is easy and the joint is stable and tight. The reducer is suitable for wood stoves, boilers, and other heating appliances with matching connection diameters. Choosing the correct reducer supports optimal draft and safe exhaust removal.
