The Multiquip EM20340 Roll Over Valve Grommet is a genuine OEM component designed for a range of Multiquip and Whiteman equipment including PRO12 stationary mixers, WBH-16 power buggies, the AR14H asphalt ride-on roller, and JWN24 ride-on trowel models. As a direct-from-manufacturer part, EM20340 meets the exact material and dimensional specifications of the original component it replaces. This grommet fits across a broad lineup including WBH-16E, WBH-16EAWD, WBH-16EAWDF, WBH-16EF, WBH-16F, WBH-21EF, WBH21EPA, PRO12E51, and PRO12E53 models, making it a versatile stocking item for mixed fleets.
Key Features
- Genuine OEM Material Grade — Manufactured to the exact rubber compound and durometer specification required for a roll over valve application, ensuring a proper seal under operating conditions.
- Direct Drop-In Replacement — Dimensionally identical to the original grommet, seating into the valve port without trimming, shimming, or reworking the mounting area.
- Broad Fleet Coverage — Confirmed fit across PRO12 stationary mixers, WBH-16 and WBH-21 power buggies, AR14H roller, and JWN24 ride-on trowels, consolidating your parts inventory across multiple machine types.
- Fuel System Integrity — A correctly seated grommet maintains a secure, vibration-resistant interface around the roll over valve, preventing fuel vapor escape and protecting the surrounding fuel system components.
- Safety-Relevant Fuel Component — The roll over valve controls fuel flow in tip-over situations; a cracked, hardened, or improperly seated grommet compromises that protection and should be replaced at the first sign of deterioration.
The roll over valve grommet forms a sealing interface between the roll over valve and its mounting point in the fuel system. Its role is to isolate the valve from vibration and prevent fuel vapors or liquids from bypassing the valve housing. When the grommet deteriorates — through heat cycling, fuel exposure, or simple age — it can harden, crack, or distort, breaking the seal and allowing fuel vapor migration or seepage around the valve. Replacing a worn grommet promptly restores the integrity of the roll over valve assembly and keeps the fuel system functioning as designed.
