All of our super-durable tanks are made from military grade, cross-linked polymer and come with a 5 year limited warranty on the tank body. Cross-linked polymer is a space-age material designed to perform in any conditions –extreme hot and cold temperatures alike. The term “cross-linked” means that the molecular chains that make up the polymer are chemically bonded together, or “bridged”, to form a continuous, three-dimensional structure. This allows stress and impact energy to be dissipated throughout the infinite chain of molecules. In other words, the TITAN Fuel Tank’s innovative cross-linked structure makes it as much as 20 times more durable than linear polymer stock (OEM) tanks. In fact, it is one of the reasons why the U.S. Department of Defense utilizes the very same processes, materials and expertise for fuel storage in many of their front-line, combat vehicles.
