Utilize double-wall construction for ultimate safety and reliability. The outer tank is made of leak-proof, weld-free galvanized steel and is roll-seamed with an oil and fire-resistant seal. This outer steel tank layer can contain up to 110% of the capacity of the inner tank for maximum protection. The inner tank is made of blow-molded, high-density, seamless polyethylene that is leak proof and will never corrode. Our double wall tanks are available in several different sizes, providing more flexibility for placement in any garage, service station or lube shop.

Fluidall’s double wall tanks meet UL SU2258 standards. They are rust resistant inside and out and are designed to prevent spills, leaks and fires. Each tank undergoes thorough testing, including ultra-sound and pressure testing, to ensure optimal wall thickness.
