The Multiquip 2773520113 Muffler Gasket is a genuine OEM component designed for B46S90 walk-behind power trowels. As an OEM part, it is manufactured to the exact material and dimensional specifications required for a proper exhaust seal on your machine. Verified fitment for the B46S90 means this gasket installs correctly the first time, with no guesswork on compatibility. DHS Equipment stocks this part to keep your trowel running at full capacity.
Key Features
- Genuine OEM Exhaust Sealing Material — Produced to the precise heat-resistant compound specification required for muffler-to-engine interface sealing on power trowel applications.
- Direct-Fit Installation — Matches the exact bolt pattern and flange profile of the B46S90 exhaust assembly, seating flush without trimming or shimming.
- Confirmed Fitment for B46S90 — Verified for Whiteman B46S90 walk-behind power trowels, so you can order with confidence.
- Exhaust Integrity Maintained — A sound muffler gasket prevents exhaust gases from leaking at the joint, protecting operator safety and maintaining proper engine back-pressure for consistent trowel performance.
- Safety-Relevant Exhaust Seal — A failed or deteriorated muffler gasket allows hot exhaust gases to escape at the engine interface, posing a burn and carbon monoxide risk to the operator — replacing it promptly is a genuine safety measure.
The muffler gasket forms an airtight seal between the engine's exhaust port and the muffler body, containing combustion gases and directing them safely out of the engine. Without a sound gasket at this joint, exhaust gases can escape at the connection point, leading to increased noise, heat exposure near the operator, and potential engine performance issues caused by incorrect exhaust flow. When a gasket deteriorates — through heat cycling, vibration, or normal wear — it should be replaced as part of routine exhaust service to maintain both safe operation and engine efficiency.
