The Alltrux ATX21685 T-Chain Style Fuel Cap replaces OEM 20770657 and is designed as a direct replacement for Peterbilt heavy-duty truck fuel tank applications. Featuring a tethered T-chain design, this cap helps prevent loss during fueling while maintaining a secure seal that protects the fuel system from contamination and vapor leakage.
Fuel caps are critical components for maintaining fuel tank integrity by preventing dirt, moisture, and debris from entering the fuel supply. A properly sealing cap helps preserve fuel quality, supports consistent engine performance, and reduces the risk of contamination-related fuel system issues in demanding commercial trucking environments.
Engineered for durability in fleet and vocational applications, this tethered fuel cap provides dependable sealing and convenience for drivers and maintenance personnel who require reliable, easy-to-use fuel tank hardware. Always verify filler neck size and application compatibility prior to installation to ensure proper fitment.
