20 litre jerry cans are made from high density polyethylene food grade material so are food safe. Their main purpose is for water storage but are not just limited to this. The pourer is a feature that makes it easy to dispense liquids with out spillage. When pouring out of the 20 litre jerry can you can open the second cap to allow for the suction pressure to regulate. This eliminates the glugging action and hence no spillage. The product is designed tall and slim so it is easy to carry, has better storage and with the wide handle grip it is easy on the hand. The IFP Group tap can also be used in the bottom bung hole (part #18022010000) IFP Group has many options in liquid dispensing and storage so if there is something you can not find contact our team. They are more than willing to help.
