The Multiquip A400449101 Fuel Cap Gasket is a genuine OEM component designed for GBX series balloon lighting systems and towable towers, including the GBX24S, GBX24B, GBX24BK, GBX12S, and GBX12SK. As a direct factory replacement, this gasket seals the fuel cap opening to prevent fuel vapor escape and contamination ingress, keeping the fuel system intact during operation and transport. Sourced directly from Multiquip, part number A400449101 meets the same fit and material standards as the original production component. If your current fuel cap gasket is cracked, compressed, or leaking, this OEM part restores the proper seal without any guesswork on compatibility.
Key Features
- OEM Fuel System Sealing: — Manufactured to the same material and compression specification as the original, ensuring a consistent fuel-tight seal at the cap interface.
- Drop-In Cap Replacement: — Seats directly into the fuel cap on GBX series units with no trimming or modification — installs exactly as the original did from the factory.
- Broad GBX Series Coverage: — Confirmed fitment across GBX24S, GBX24B, GBX24BK, GBX12S, and GBX12SK balloon lighting and towable tower models.
- Vapor and Contamination Control: — A compromised fuel cap gasket allows fuel vapors to escape and lets moisture or debris enter the tank; replacing it promptly protects engine performance and fuel quality.
- Fuel System Safety: — A properly sealed fuel cap is critical on equipment that operates near open-flame or high-heat sources; a failed gasket can present a vapor leak risk on active worksites.
The fuel cap gasket forms the primary seal between the fuel cap and the filler neck of the tank. Its job is to prevent fuel vapors from venting uncontrolled and to block water, dust, and debris from entering the fuel supply. Over time, exposure to heat cycling and fuel chemistry causes the gasket material to harden, compress, or crack — at which point the seal fails and the cap no longer closes the system properly. Replacing a worn gasket with a genuine OEM part like the Multiquip A400449101 restores the integrity of the fuel system and ensures the cap performs as intended across the full operating life of the machine.
