NEW Dualline sizes! 2000 & 2500 Gallon


Dualline™ Double Wall Tanks

Dualline tanks are free standing double wall tanks with flat bottoms for indoor or outdoor stationary applications. The double wall construction provides containment in the event the inner or primary tank is compromised.

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.
