Multiquip EE60620 Locking DEF Tank Cap with Lanyard - OEM Replacement Part

This locking DEF tank cap with integrated lanyard provides secure closure and theft protection for Multiquip DEF replenishment systems. The cap threads onto the DEF fill port (component #3 in the DEF tank assembly) and must be removed when filling the tank. The attached lanyard prevents cap loss during refueling operations and keeps the cap secured to the unit when open.

Designed for outdoor industrial environments, this lockable cap helps prevent contamination of the DEF fluid inside the polyethylene storage tank and provides security against unauthorized access or tampering. The lanyard attachment ensures the cap remains with the equipment during the filling process, which is critical for maintaining system cleanliness and preventing debris from entering the tank. According to Multiquip service documentation, the cap should be kept clean and properly secured after each filling operation to maintain fluid integrity.

Compatible with the following Multiquip DEF tank models:

• DEFTANK1 (100-gallon capacity)
• DEFTANK302 (300-gallon capacity)
