The Norwesco 7-gallon portable flat-bottom utility tank is a compact white polyethylene vessel built for small-batch transport and dispensing where a full-size loaf tank would be overkill. It measures 18 inches tall on a 9 x 14 inch footprint and holds 7 gallons. The flat bottom sits stable on a truck bed, shelf, or skid without a cradle, and at 18 inches tall on a 9 x 14 inch base it slides into a standard bed rail or shelf depth most installers already have. The white tank wall lets you eyeball the fill level at a glance. Note one ordering rule up front: this Norwesco white utility tank ships in increments of four units per order.
Will it work for your job?
This tank is rated to a 1.5 specific gravity, so it carries the full 7 gallons of water (about 58 pounds full) and has real headroom for denser contents up to roughly 88 pounds of rated weight. That 30-pound reserve means it is rated for contents up to about 1.5 times the weight of water, so a light fertilizer or utility liquid is already inside its envelope without stepping up to a heavier tank. Mounting and filling use molded-in hardware: four 5/16-18 threaded inserts in the body for strap-down or bracket bolts, plus a neck sized for a 5-inch cap for filling and venting. See the technical drawing on this page for exact insert placement and the cap-neck dimension before you spec a bracket. If you are choosing between this 7-gallon size and a larger portable tank for a sprayer or farm setup, the Tank Sizing Calculator and Tank Sizing Guide match capacity and weight to your vehicle and stand.
What you need to add
The fittings are named but not bundled, so plan the small parts. Filling and venting run through the 5-inch cap-neck, which means you source a 5-inch cap or lid and its gasket separately. Mounting runs through the four 5/16-18 inserts, so bring matching 5/16-18 bolts rather than a standard pipe or bulkhead fitting. These are an inserted utility thread, not a pipe size, so the matching bolt is the right hardware, not a tank bulkhead.
The mistake to avoid
The order rule is the thing buyers miss: this tank must be ordered in increments of four, so a single-unit order will not process. Plan the quantity in multiples of four and size the freight to match. Four tanks run roughly 232 pounds full of water (about 58 pounds each) on a single pallet, which is why this moves as palletized freight rather than parcel. The 1.5 specific gravity rating covers water and typical light utility liquids; this is sold as a water and utility tank, so confirm any non-water contents against the manufacturer's chemical-resistance guidance before filling.
Freight and ordering
This tank is manufactured at the Norwesco plant in Sheldon, Iowa, and ships LTL freight quoted live to your ZIP code. Because it ships in four-packs, palletized LTL is the practical mode rather than parcel. Get an exact freight number with the Freight Cost Estimator, or call 866-418-1777 and we will quote the four-unit order to your delivery point. If you run portable utility tanks on a farm fleet, the guide on Norwesco loaf-style portable utility tanks and the 49 CFR 173.5 agricultural exemption covers DOT classification for farm use, and our concrete pad sizing guide helps if you are building a permanent stand for a bank of these tanks.
