The Alltrux ATX20269 Lockable Fuel Cap with Keys replaces OEM 11-04859-200 and is designed to provide secure sealing and theft protection for heavy-duty truck fuel tanks. Featuring an integrated locking mechanism, this anti-theft fuel cap helps prevent unauthorized fuel access while maintaining proper tank sealing and fuel system integrity in demanding commercial operating environments.

A secure fuel cap plays a critical role in protecting fuel quality by preventing dirt, moisture, and debris from entering the tank while also deterring fuel theft in unattended or high-traffic locations. Replacing worn or non-locking caps with a durable lockable design helps safeguard fuel supply, reduce tampering risks, and support consistent engine performance across fleet and vocational applications.

Built for heavy-duty truck service conditions, this lockable fuel cap is ideal for fleet maintenance programs, owner-operators, and vehicles operating in remote or unsecured environments where fuel security and reliable tank sealing are essential. Always verify filler neck size and compatibility prior to installation to ensure proper fitment.
