A new generation of jerry jugs, these special fuel containers feature a spill-proof fueling system that meets new, tough ARB regulations in CA, NY, MD, DE and PA. Those environmental regulations prohibit the sale of open, vented fuel cans within the state. Containers are made from HDPE and DuPont?s Selar RB Barrier resin to meet strict permeation requirements. The ECO Spout is easy to use and helps to prevent spills. Fuel flow will automatically stop when the container is full. Spout closes automatically. All ECO Fuel Can products shown have been UL-tested and approved.
