The Wacker Neuson Muffler Gasket is a genuine OEM component designed for RD12-90 Tandem Rollers and CRT36-25 Ride-on Trowels. Sourced directly from Wacker Neuson, this part carries the same specification as the gasket installed at the factory — ensuring a correct, leak-free seal between the exhaust port and muffler. It fits both the standard and foldable ROPS configurations of the RD12-90, as well as the 915mm/36in CRT36-25 Ride-on Trowel with and without the Wheel Kit.
Key Features
- OEM Sealing Integrity — Manufactured to the exact material grade and compression specification required for a gas-tight exhaust seal, preventing leaks that could affect back-pressure and engine performance.
- Drop-In Replacement — Matches the original bolt pattern and mating surface dimensions, fitting directly between the exhaust port and muffler with no rework to surrounding hardware.
- Broad Model Coverage — Compatible with RD12-90 Tandem Rollers (solid and foldable ROPS) and CRT36-25 Ride-on Trowels, including Wheel Kit variants, under a single part number.
- Sustained Exhaust Efficiency — A sound muffler gasket maintains proper exhaust flow and back-pressure, supporting consistent engine output during compaction and finishing operations.
- Emission and Safety Compliance — An intact exhaust gasket keeps combustion gases routed through the muffler and away from the operator, which is especially important on ride-on equipment with an enclosed ROPS environment.
The muffler gasket forms a pressure-tight seal between the engine's exhaust outlet and the muffler body, preventing hot exhaust gases from escaping at the joint. A functioning gasket keeps exhaust flow directed correctly through the muffler, which controls noise levels and maintains the engine's designed back-pressure for efficient combustion. When this gasket deteriorates or burns through, exhaust gases leak at the joint, producing a loud ticking or hissing noise, reducing muffler effectiveness, and exposing nearby components — and the operator — to uncontrolled heat and fumes.
