The Norwesco 25 Gallon Vertical Liquid Storage Tank (N-41867) is a compact polyethylene vertical tank standing 29 inches tall on an 18-inch diameter footprint. Filled with water it holds about 208 pounds, and its 1.5 specific gravity rating means it is designed to carry up to roughly 313 pounds of contents at maximum density - real headroom for liquids heavier than water within that rating. The narrow 18-inch base makes it a sensible fit for tight equipment rooms, truck beds, utility sheds, and small fluid-handling stations where a full-size vertical storage tank simply will not fit.
Will it work for your application?
This is a Norwesco vertical storage tank in polyethylene, sized for low-volume water and liquid storage. The two dimensions to plan around are 29 inches of height and 18 inches of diameter at the widest point; confirm both your overhead clearance and your floor or pad footprint against those numbers before ordering. The 1.5 SG rating is the figure that matters most for matching the tank to your liquid - water sits at 1.0, so a 1.5 ceiling covers water and most common solutions with room to spare. To confirm the right capacity and stand-up dimensions, run your numbers through the Tank Sizing Calculator or read the Tank Sizing Guide. The standard fitting size and outlet location, the base wall profile, and the dry tank weight are all called out on the technical drawing on this page - confirm thread type and gasket spec there before you plumb the tank.
How it ships
Norwesco builds this 25 gallon tank across a wide plant network, so it ships LTL freight from the location nearest you - including Burnet, TX; Fairfield, TX; Griffin, GA; Hanford, CA; Lancaster, OH; Owego, NY; Shawnee, OK; Sheldon, IA; St. Bonifacius, MN; Tooele, UT, and Washougal, WA. Shipping from the closest plant keeps transit distance and freight cost down. Because freight is quoted live by ZIP code rather than baked into the listed price, use the Freight Cost Estimator to get a real number to your address.
The mistake to avoid
The most common error with a tank this size is treating the specific gravity rating as a suggestion. The 1.5 SG rating is a ceiling, not a license - it is the heaviest liquid density the wall is engineered to support. Water (1.0) and most common solutions sit well under it, but some concentrated acids and brines exceed 1.5 and would call for a higher-rated tank, so verify your fluid's actual specific gravity before you fill. The second mistake is over-mounting heavy plumbing onto a compact 18-inch-diameter shell; keep external loads supported independently and use the fitting layout on the technical drawing as your guide. If this tank is going on an outdoor pad, our guide on concrete pad sizing for above-ground polyethylene tanks walks through getting the base right the first time.
