Tuff Jug DEF Jug

Perfect for all your DEF fluid needs, the DEF Jug stands out with bold double-sided "DEF" lettering so it never gets mixed up with your other containers. It includes a DEF Adapter, sized to fit smaller DEF inlets for a secure, spill-free pour. A pre-installed external vent keeps liquid flowing fast and steady, while the light blue cap matches the industry-standard DEF color for instant identification at a glance.
