4″ Bellows (102mm I/D x 203mm Long)

The 4 inch (102mm I/D) stainless steel exhaust bellows in 203mm length is a heavy-duty industrial component for large-bore exhaust systems where the 4 inch specification is standard. This bore size is found across a broad range of heavy plant equipment including crushing and screening machinery, large mobile and stationary generator sets, and heavy construction and earthmoving equipment operating throughout UK and Irish quarry, construction and industrial sites.

The 2-ply convoluted stainless steel construction handles the substantial axial, lateral and angular forces generated by high-output diesel engines under continuous heavy load, providing greater movement capacity and fatigue resistance than single-ply alternatives. The weld-on end connections allow direct installation into fabricated exhaust pipework and system replacements. Stainless steel construction throughout ensures long-term corrosion resistance and durability in outdoor industrial environments
