Multiquip 42009-10 Exhaust Manifold Outlet Gasket 3 Hole

The Multiquip 42009-10 is a genuine OEM Exhaust Manifold Outlet Gasket 3 Hole designed for the HTXG6DF heavy-duty hydrostatic ride-on power trowel. As a factory-original component, this gasket is manufactured to the exact material and dimensional specifications required for a proper exhaust seal on the HTXG6DF. DHS Equipment stocks this part to help you keep your trowel running at full capacity with zero compromise on fit or sealing integrity. Confirm your model against part number 42009-10 before ordering to ensure correct application.

Key Features

• Genuine OEM Sealing Material — manufactured to the exact heat and compression tolerances required for an exhaust manifold outlet application, not a generic gasket substitute.
• Three-Hole Configuration — the 3-hole bolt pattern matches the outlet flange on the HTXG6DF exhaust manifold directly, installing with the same hardware and torque sequence as the original.
• Confirmed Fitment for HTXG6DF — sourced and verified for the Multiquip HTXG6DF heavy-duty hydrostatic ride-on trowel series.
• Exhaust Integrity Maintained — a sound exhaust gasket keeps combustion gases fully routed away from the operator and engine bay; a failed gasket allows hot exhaust leaks that can damage surrounding components and create hazardous conditions.
• Exhaust System Safety — replacing a cracked or blown exhaust manifold gasket promptly is essential to operator safety; exhaust leaks near the engine compartment of a ride-on trowel pose a direct carbon monoxide and heat risk.

The exhaust manifold outlet gasket seals the junction between the exhaust manifold and the outlet pipe or downstream exhaust component, preventing hot combustion gases from escaping at the flange joint. On a ride-on power trowel like the HTXG6DF, the engine operates under sustained load for extended finishing runs, which places considerable thermal stress on exhaust sealing surfaces. When this gasket deteriorates or blows, the resulting exhaust leak reduces back-pressure, creates noise, and can direct dangerous gases toward the operator platform — making prompt replacement with a correctly specified part like the 42009-10 a priority maintenance item.
