The Multiquip 520820 is a genuine OEM Fuel Cap EPA 2 Inch Diameter designed for a wide range of Multiquip power buggies, rollers, and stationary mixers. This EPA-compliant cap is a direct-fit replacement for WBH-16 and WBH-21 series Whiteman hydraulic power buggies, the AR14H asphalt ride-on roller, and PRO12 series Essick stationary mixers. As a genuine OEM part, Multiquip 520820 is manufactured to the exact specifications of the original component, ensuring a correct seal and proper fuel system integrity across every compatible model. Sourced direct from Multiquip, this cap ships as an authorized replacement you can install with confidence.
Key Features
- EPA-Compliant Fuel System Sealing — Meets EPA evaporative emission standards, ensuring the fuel tank vents and seals correctly without fuel vapor escape.
- Exact 2-Inch Diameter Thread Fit — Engineered to the original 2-inch diameter specification for a secure, rattle-free fit on the fuel tank filler neck without tools or adaptation.
- Wide Fitment Coverage — Compatible with WBH-16 and WBH-21 series power buggies, the AR14H roller, and PRO12 series Essick mixers — one part number across multiple Multiquip product families.
- Fuel Containment When It Counts — A properly sealing fuel cap prevents contamination, fuel loss, and pressure imbalance in the tank; a cracked or missing cap can disrupt engine fuel delivery and create a fire hazard on the worksite.
- Genuine OEM Construction — Produced to Multiquip's original material and thread specification, so the cap seats and releases the same way as the factory-installed unit every time.
The fuel cap seals the fuel tank filler opening on the machine, keeping fuel contained while allowing the tank to breathe through a controlled vent path that meets EPA evaporative emission standards. A correctly functioning cap maintains the right pressure balance inside the tank, which supports consistent fuel delivery to the engine. When a fuel cap is cracked, missing, or no longer seals properly, it can allow fuel to spill or evaporate, introduce debris into the tank, and in some cases restrict fuel flow enough to cause hard starting or stalling.
