The Bomag 05742774 Catalytic Converter Gasket is a genuine OEM component designed for Bomag BW 161, BW 174, BW 190, and BW 202 tandem rollers. Sourced directly from Bomag, this gasket delivers an exact match to the original sealing surface geometry, ensuring proper exhaust containment at the catalytic converter joint. It is the correct service replacement for machines including the BW 161 AD-5, BW 161 AC-5, BW 161 ADO-5, BW 174 AP-4i, BW 174 AP-4i AM, BW 174 APO-4i, BW 174 ACP 4I AM, BW 190 AD-5, BW 190 ADO-5, and BW 202 AD-5 tandem rollers. Choosing a genuine OEM part means the sealing material, thickness, and compression characteristics meet the same standards as the original build.
Key Features
- Genuine OEM Sealing Integrity — manufactured to the same material grade and compression specification as the original gasket, maintaining an airtight seal at the catalytic converter interface
- Direct Drop-In Replacement — engineered to match the original bolt pattern and mating surface profile for straightforward installation without rework
- Broad Tandem Roller Coverage — compatible with BW 161, BW 174, BW 190, and BW 202 series tandem rollers, including the BW 161 AD-5, BW 174 AP-4i, BW 190 ADO-5, BW 202 AD-5, and additional variants
- Exhaust Leak Prevention — a correctly seated catalytic converter gasket prevents hot exhaust gases from escaping the joint, protecting surrounding components and maintaining emissions system performance
- Emissions System Compliance — retaining a proper seal at the catalytic converter is essential for meeting engine emissions requirements; a failed or leaking gasket can compromise aftertreatment function and trigger regulatory non-compliance on regulated worksites
The catalytic converter gasket creates a gas-tight seal between the catalytic converter and its adjoining exhaust components, preventing hot combustion gases from bypassing the aftertreatment system. A properly sealed catalytic converter allows the emissions control system to function as designed, reducing harmful exhaust output and keeping the engine operating within required emissions standards. When this gasket deteriorates or fails, exhaust leaks at the joint can cause heat damage to nearby components, produce audible exhaust noise, and result in emissions system faults that may sideline the machine.
