The Norwesco 300 Gallon Vertical Liquid Storage Tank (part #40213) is a 300-gallon polyethylene tank in natural white, standing 79 inches tall on a 35-inch diameter with a 35-inch round footprint. This is specifically the tall, narrow version of the 300-gallon vertical line, built for sites where floor space is tight but vertical clearance is available, and it carries a 1.5 specific gravity rating, meaning it is built to hold liquids up to 50 percent denser than water by weight.
Will this Norwesco vertical tank work for your storage
Filled with water, this tank weighs roughly 2,502 pounds, and at its full 1.5 specific gravity rating it is built to carry up to 3,753 pounds of contents. That heavier-than-water rating is the reason to choose this tank over a standard water-only vertical storage tank: it covers many agricultural and light-industrial liquids by weight, where a derated tank would not. Use those figures to plan the base, because a 300-gallon tank concentrates real load onto a 35-inch circle, so a level, fully supported concrete pad or compacted stand is not optional. Note the geometry before you order: this is the tall 35" x 79" tank, not the squat 46" x 50" version, so make sure you have at least 79 inches of vertical clearance plus room above for the fill and fitting access at the top. If you are still weighing capacity against your space, the Tank Sizing Calculator and Tank Sizing Guide walk footprint, height, and weight through together.
Fittings and what to confirm before you buy
Confirm the fitting and outlet layout against the technical drawing on this page before you order, and match any bulkhead or valve hardware to that configuration rather than assuming it. Because the as-supplied outlet detail is best confirmed directly, call us at 866-418-1777 with your intended use and we will verify the fitting and outlet setup for #40213 before it ships. The 1.5 specific gravity rating tells you what the tank wall can safely hold by weight, but it does not by itself qualify the tank for a specific chemical: two separate things decide chemical service, the polyethylene wall plus its SG-by-weight limit, and the gasket or o-ring material on any bulkhead fitting, which must be matched to the stored liquid on its own (EPDM and FKM/Viton behave very differently). If you are storing anything other than water, verify your liquid's specific gravity stays at or below 1.5 and confirm gasket compatibility before filling. For straightforward water storage, it is ready to work as a vertical storage tank.
