The Multiquip 17631Z4H800 is a genuine OEM Fuel Filler Cap Gasket designed for CA4HM walk-behind power trowels, WM120SH, WM120PH Whiteman mixers, and EM120S and EM120P series Essick mixers. As a direct Multiquip OEM component, it delivers an exact material match to the original gasket, ensuring a proper seal every time. Sourced directly through authorized Multiquip supply channels, the 17631Z4H800 is the correct replacement when your existing fuel filler cap gasket shows signs of cracking, compression loss, or fuel odor around the cap.
Key Features
- OEM Material Match — Manufactured to the same material grade and compression spec as the original gasket, maintaining a consistent fuel-tight seal under operating conditions.
- Drop-In Replacement — Seats directly into the fuel filler cap housing with no trimming or adaptation, restoring the cap assembly to its original condition.
- Broad Multiquip Fitment — Compatible with CA4HM, WM120SH, WM120PH, EM120S series, and EM120P series equipment, covering multiple Multiquip and Whiteman product lines.
- Fuel System Integrity — A properly sealing cap gasket prevents fuel vapors from escaping and keeps contaminants out of the fuel tank, protecting engine performance over time.
- Fuel Vapor Containment — A failed or compressed gasket allows fuel fumes to vent freely around the cap, creating a safety concern on any gasoline-powered machine — this OEM gasket restores the designed containment.
The fuel filler cap gasket forms the sealing interface between the fuel cap and the tank filler neck, preventing fuel vapors from escaping and blocking dirt, debris, and moisture from entering the fuel supply. Over time, heat cycling and exposure to gasoline cause the gasket material to harden, compress, or crack, which compromises both the seal and fuel system cleanliness. A worn gasket should be replaced promptly to maintain safe operation and protect the engine from contaminated fuel.
