The Multiquip 18331ZE3811 is a genuine OEM Muffler Cap designed for a wide range of Multiquip and Whiteman equipment, including MRH800GS rollers, MVH208GH, MVH308GH, and MVH408GH plate compactors, V305EH rollers, MC12PH mixers, SP118 and SP1CE13H18 saws, and WM120SH, WM120PH, EM120S Series, and EM120P Series mixers. Sourced directly from Multiquip, this part carries the same fit, form, and function as the component installed at the factory. Keeping an exact-match cap on the muffler protects the exhaust system and helps maintain safe, consistent operation across every machine in this lineup.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications, ensuring the cap seats and seals correctly on the muffler outlet without gaps or distortion.
- Direct Drop-In Replacement — Matches the original mounting points and profile of the muffler assembly, so installation requires only basic hand tools and no custom fitting.
- Broad Equipment Compatibility — A single part number covers rollers (MRH800GS, V305EH), heavy-duty plate compactors (MVH208GH, MVH308GH, MVH408GH), mixers (MC12PH, WM120SH, WM120PH, EM120S Series, EM120P Series), and flat saws (SP118, SP1CE13H18).
- Exhaust System Integrity — A correctly fitted muffler cap contains exhaust flow and reduces spark and debris ejection from the muffler opening, which matters on active worksites where combustible materials may be present.
- Spark and Debris Containment — A worn or missing muffler cap can allow hot exhaust gases and particulate to exit uncontrolled — replacing it promptly restores the exhaust system to its designed operating condition.
The muffler cap fits over the exhaust outlet of the muffler assembly, closing off the opening to direct exhaust gases away from the operator and control the discharge of combustion byproducts. On equipment like plate compactors, rollers, mixers, and saws, the cap also acts as a barrier against debris ingestion into the muffler when the engine is shut down. When the cap cracks, warps, or goes missing entirely, uncontrolled exhaust discharge can create a safety hazard and accelerate corrosion inside the muffler body itself.
