Description

The Tuff Jug 5 Gallon DEF Jug is built for one job: keeping diesel exhaust fluid clean, separate, and easy to pour. Bold double-sided DEF lettering and a light blue cap that matches the industry-standard DEF color make it easy to pick out from every other container in the truck bed or shop. It's made for diesel truck owners, farmers, contractors, and fleet operators who top off DEF on a regular basis.

The Auto-Stop Spout shuts off flow automatically the moment your tank is full, so you fill clean without watching for overflow. For smaller DEF inlets, the included DEF Adapter fits onto the spout for a secure, spill-free pour. A pre-installed external vent keeps liquid flowing fast and steady.

Built Tuff from multi-layer HDPE, the 20-liter jug holds up to daily use on the jobsite, farm, and fleet yard. The included Storage Cap seals the jug for storage and transport, and the ergonomic side handle gives you leverage and control pouring a full jug.

Made in the USA in Nampa, Idaho. Backed by a lifetime warranty on materials and workmanship.
