UWS (ST-75-COMBO-MB): 75-Gallon Steel-Aluminum Combo Transfer Tank

The first combo transfer tank ever constructed from high-strength carbon steel and aluminum, this exclusive UWS innovation combines the strength of a 14-gauge steel tank with the light weight of a 0.08” aluminum toolbox—creating a product that weighs up to 100 lb. less than competing models with a steel toolbox and reduces the burden on your truck.

UWS transfer tanks are built and tested for transporting non-flammable liquids—including diesel—to on-site vehicles and machinery. Whether you’re headed out to the field or driving to the construction site, a transfer tank dependably transports liquids such as diesel fuel; chemicals; solutions; or even water for cleaning, farming, and more.

Featuring a smooth, milled finish—in contrast to the more common diamond plate—this L-shaped tank offers a unique look in your truck bed. ST-75-COMBO-MB features a matte-black powdercoat.

Made right here in the USA, these UWS transfer tanks are fully pressure tested and come with a lockable, commercial-grade cap; integrated drain plug; and internal baffle for a smooth liquid transfer. 1/8” tabs are included for mounting in your truck bed, but mounting hardware is not included. DOT-compliant for Class 3 combustibles.
