BikeMaster® 5 Gallon Utility Jug has a squared-off design for flush fit against flat surfaces, minimizing the chance of rolling or spilling. Made with HDPE ( High-Density Polyethylene) for toughness, strength, stiffness and resistance to chemical and moisture. The 3/4" flexible clear hose with auto shut off built into the hose which eliminates over poring and allows for a quicker pour. Fluid stops flowing after reaching the end of the hose automatically.
