Buyers Products Pickup Truck Storage Tanks are a convenient and portable storage solution for non-flammable liquids such as potable water and agricultural and industrial chemicals. Produced from pure, medium density polyethylene, the tanks have UV-inhibiting stabilizers so you can store liquids outdoors for longer periods of time. They have a maximum contact operating temperature of 110-F. The translucent material has visible gallon and liter markings for quickly assessing the amount of liquid inside. The tanks have a built-in bulkhead fitting for easy siphoning and an easy-tighten cap with a wide opening for quick fill-ups.
