Delta tanks are built to last with their 14-gauge construction and internal baffles that add extra strength and control the flow of contents when moving. They are pressure tested for leaks to ensure quality. The tanks also feature 2-inch NPT reinforced bungs that allow for convenient use from either side, although a filter system is recommended. Built-in lifting rings make it easier to lift and move an empty tank, while a lockable filter cap and coupler prevent excessive pressure buildup. Heavy-duty brackets secure the tank to the truck bed, but they must be bolted to the truck bed. These tanks are suitable for non-flammable liquids and diesel fuel, and come in a square shape with a volume of 96 gallons. They are made of steel and available in white color.
