The Norwesco 25 gallon rectangular flat bottom utility tank (SKU 45879) is a compact, portable polyethylene tank built for hauling and utility service where a low profile matters. At 34" long, 14" wide, and just 12" tall, its flat, rectangular shape rides low in truck beds, UTVs, and trailer decks where a taller round tank is awkward — and it ships LTL freight from Texas, so freight is a real part of the buying math on a tank that weighs only 15 pounds empty.
Specs that decide the purchase
Capacity is 25 gallons in a white polyethylene shell with FDA approved material and a maximum service temperature of 120 F (48 C). The specific gravity rating of 1.5 is the number to notice: it means the shell carries density headroom well beyond plain water, not just water at the brim. Openings are minimal by design — a 5" lid up top for filling and inspection, and a 0.75" outlet, matching the "with fitting" configuration in the product name. The 14.0" x 34.0" footprint sits flat on any level surface that supports the full base; no cradle or saddle required.
Weight when full — check your vehicle first
Filled with water, tank plus contents comes to about 208 pounds; at the full 1.5 specific gravity rating, maximum contents weight is 313 pounds. Before strapping this rectangular flat bottom tank into a UTV bed or small trailer, confirm your payload rating covers that load and secure the tank so 200+ sloshing pounds can't shift under braking. For truck and farm-fleet use, our guide to Norwesco loaf-style portable utility tanks and the 49 CFR 173.5 agricultural exemption covers the transport rules. Sizing between this and a larger tank?

The mistake to avoid
Don't treat the 0.75" outlet as an afterthought. Confirm your pump or hose connection matches that 0.75" size before the tank arrives — mismatched plumbing is the most common reason a portable utility tank sits unused on delivery day. And keep contents under the 120 F rating; a dark truck bed in summer sun pushes stored liquid hotter than you'd guess.
