The Multiquip EM203403 Roll Over Valve Grommet is a genuine OEM component designed for PRO12, AR14H, WBH-16, and WBH-21 series equipment. This grommet serves as a critical sealing element within the fuel system, securing the roll over valve and protecting against leaks or fuel vapor escape during operation. Sourced directly through Multiquip's OEM supply chain, EM203403 ensures a consistent, application-specific fit across compatible Essick stationary mixers, Whiteman hydraulic power buggies, and the AR14H asphalt ride-on roller. If your machine is showing signs of fuel vapor loss or a loose, deteriorated valve grommet, this is the correct factory replacement part.
Key Features
- Genuine OEM Fuel System Integrity — Manufactured to Multiquip's original material and dimensional specifications, ensuring the grommet seats and seals the roll over valve correctly without deformation under fuel exposure.
- Direct Drop-In Replacement — Engineered to install in the same valve pocket as the original, requiring no trimming, adapting, or reworking of the surrounding housing.
- Broad Compatible Fitment — Confirmed fit across PRO12 and PRO12E series Essick stationary mixers, WBH-16 and WBH-21 series Whiteman hydraulic power buggies (including AWD and foam-filled tire variants), and the AR14H asphalt ride-on roller.
- Maintains Fuel Vapor Containment — A correctly seated roll over valve grommet prevents fuel vapor from escaping the fuel system, supporting clean-running operation and protecting surrounding components from fuel degradation.
- Fuel System Safety Component — The roll over valve and its grommet are part of the machine's fuel containment system. A cracked, hardened, or missing grommet can allow fuel vapor to vent uncontrolled, making prompt replacement important for safe machine operation.
The roll over valve grommet forms a compression seal between the roll over valve body and the fuel tank or housing it mounts into. The roll over valve itself is a safety device that closes automatically if the machine tips over, preventing fuel from spilling out of the tank. The grommet ensures this valve is held securely in place and that no fuel or fuel vapor bypasses the valve seat. When the grommet hardens, cracks, or deteriorates from age and fuel exposure, the seal fails — allowing vapor escape or, in a tip-over event, reducing the effectiveness of the valve's shutoff function.
