The 1000 gallon Dualline is a freestanding double wall vertical tank with a flat bottom for indoor stationary applications.  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.


  • Furnished with a 16” vented lid assembly as standard.
  • Three fitting flats are provided on the top for custom tank plumbing.
  • A 1” service fitting is provided on the secondary tank in the event that the containment requires evacuation.
  • Tanks manufactured from linear low density polyethylene with U.V. stabilizers.
  • Standard colors are white, yellow and black.
  • Designed for containment of all chemicals rated for contact with polyethylene.  Standard weight tank is designed for chemicals with a specific gravity of 1.7.  Consult the Application Guideline Manual for known compatible chemicals and service temperatures.  FDA compliant materials are available.


  • Optional 2” Polypropylene Fitting with Sanoprene gasket and 316 stainless steel compression rings.  Note that optional fitting must be factory installed.  Accessory not sold separately.
