4.5″ Bellows (114.8mm I/D x 203mm Long)

This 4.5 inch (114.8mm I/D) stainless steel exhaust bellows provides a heavy-duty flexible connection for large industrial exhaust systems where the bore falls between the standard 4 inch and 5 inch range. At 203mm overall length with a 2-ply convoluted stainless steel construction, this bellows is designed for high-output generator sets, heavy industrial plant and large crushing and screening equipment with exhaust outlets in the 114-115mm range. The 4.5 inch bore size is commonly found on medium-to-large prime power and standby generator engines, as well as specialist heavy plant and industrial machinery.

The 2-ply construction delivers superior multi-directional flexibility and fatigue resistance compared to single-ply alternatives, handling the significant axial, lateral and angular loads typical of large industrial diesel engines in sustained operation. Weld-on ends for fabricated exhaust system integration. Full stainless steel construction for outdoor durability and corrosion resistance.
