Dualline™ Double-Wall Tanks

Dualline™ Double-Wall Tanks have a strong, durable, quality construction and are designed for containment in the event the inner or primary tank is compromised. Dualline™ tanks are freestanding double-walled vertical tanks with a flat bottom for indoor or outdoor stationary applications. An EPDM elastic seal is standard and seals the primary tank to the secondary tank to prevent dirt and moisture from entering the containment space between tanks.
