N-40665 | The name says it all. These storage tanks are truly “heavy duty” and can withstand some of the most corrosive chemicals. People can use these storage tanks for chemical production and for other manufacturing and industrial purposes. Common contents stored in these tanks include pesticides, herbicides, insecticides, DEF, biodiesel, liquid fertilizers and a wide variety of industrial chemicals. To extend the life of these tanks and keep them in great working condition, the resin is mixed with UV stabilizers and the tanks are rotationally molded into a one-piece structure. The 16-inch self-vented lid helps to reduce sloshing and there are tie-down slots for stability. This is a 1.9 specific gravity tank.
