Multiquip EE58386 Exhaust Flex Tubing for Cummins QSB7-G9 Tier 4F Engine - OEM Replacement Part

This exhaust flex tubing is a critical component in the exhaust system assembly for Multiquip generators equipped with the Cummins QSB7-G9 Tier 4 Final engine. The flexible tubing connects rigid exhaust sections above the diesel engine, accommodating vibration and thermal expansion while routing exhaust gases through the silencer to the roof-mounted exhaust riser with rain cap.

Designed specifically for Tier 4 Final emissions-compliant systems, this flexible section must maintain exhaust integrity in generators utilizing EGR (Exhaust Gas Recirculation), DOC (Diesel Oxidation Catalyst), and SCR (Selective Catalytic Reduction) technologies. The QSB7-G9 is a 6-cylinder, turbocharged, charge air-cooled engine with 409 cubic inch displacement, producing 282 HP at 1800 RPM. Proper exhaust system function is essential for maintaining emissions compliance and preventing exhaust leaks that could affect engine performance or create safety hazards.

Failed or deteriorated flex tubing can cause exhaust leaks, increased noise levels, and potential engine damage from back pressure issues. Regular inspection of flex sections during routine maintenance is recommended, particularly in high-hour applications.
