The Norwesco 40 Gallon Vertical Liquid Storage Tank (#44848) is a compact polyethylene vertical tank measuring 18 inches in diameter by 42 inches tall, rated to 40 gallons. With an 18-inch footprint, it slots into tight corners, equipment skids, utility rooms, and trailers where a wider vertical tank simply will not fit. The molded polyethylene construction carries a 1.5 specific gravity rating, which is what sets it apart from a plain water-only barrel: it is built to hold liquids heavier than water.
Will it work for your liquid?
Filled with plain water, this tank holds about 334 pounds of contents at 40 gallons. It is rated to a 500-pound contents ceiling, and that is exactly what the 1.5 specific gravity rating buys you. In practical terms: at 40 gallons, the tank handles liquids weighing up to roughly 12.5 pounds per gallon, versus water's 8.34. So before you order, check your liquid's specific gravity against that 1.5 limit and confirm 40 gallons matches your batch or daily volume. Run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide first.
Fittings, access, and siting
The tank has one molded fitting flat (see the technical drawing on this page for its location) plus an 8-inch lid opening at the top for filling and inspection. The flat is a single molded location, not an arbitrary one, so confirm your inlet and outlet plan against that drawing before you order valves or bulkhead fittings. For siting, remember the full load bears on that 18-inch-diameter circle: roughly 334 pounds with water, up to 500 pounds at maximum rated specific gravity. Size your floor, stand, or trailer deck for that point load.
Planning for more volume later
If there is any chance you will outgrow 40 gallons, look at the footprint jump before you commit. The next steps up are the 300 gallon at 35 inches diameter by 79 inches tall and the 500 gallon at 48 inches diameter, both far wider than this 18-inch tank. It is worth weighing the space tradeoff now rather than buying twice.
