Norwesco 20 Gallon Vertical Liquid Storage Tank without Fittings in White

The Norwesco 20 Gallon Vertical Liquid Storage Tank (SKU N-44847) is a compact white polyethylene vertical tank that stands 28 inches tall on a 16 x 16 inch square footprint. It ships without fittings, which makes it the right pick when you want to plumb your own bulkhead, valve, and outlet exactly where your application needs them rather than designing around a pre-drilled port. If you have been searching for a small Norwesco vertical storage tank that tucks into a tight bench, trailer, or utility corner, this is the size that fits.

Will it work for your job?

This is a vertical storage tank rated to a 1.5 specific gravity, so it is built to handle liquids heavier than plain water without stressing the wall. Filled with water, the contents weigh about 167 lbs, and the tank is rated to carry up to 250 lbs of contents at its 1.5 SG rating - that headroom is what lets you store denser fluids than water within the 20-gallon volume. Plan your pad or stand placement before you fill it: at roughly 167 lbs full of water this tank is easy to move empty but is not something you lift once it is charged, so set it where it will live first. One more honest dimension fact: at 28 inches tall on a 16-inch base the tank is tall relative to its width (a 1.75:1 height-to-footprint ratio), so strap or secure it on any trailer, skid, or vibrating platform. Run your volume and weight numbers through the Tank Sizing Calculator or read the Tank Sizing Guide before you commit to a size.

Plan your fittings and gasket before you order

Because this tank arrives with no fittings installed, you are choosing and placing the bulkhead and outlet yourself - and that means sourcing both the fitting and a compatible gasket separately. Decide on your outlet size, location, and gasket material before the tank is on site so installation is a single step rather than a scramble. If you want to see how the same Norwesco vertical storage tank platform scales up to larger volumes, the 300 gallon vertical buyer's guide, the 500 gallon guide, and the 2000 gallon guide walk through the same vertical line in bigger sizes.

The mistake to avoid

The 1.5 SG rating is the number to respect, and it is easy to misread. It tells you the tank wall is engineered for liquids up to 1.5 times the density of water - it does not mean the tank is approved for every fluid at that weight, and it caps the stored contents at the 250 lb maximum regardless of volume. For anything beyond water, the resin and the gasket compatibility matter as much as the specific gravity, so confirm both your liquid and your gasket material against the manufacturer's chemical-resistance guidance before filling.
