The Chem-Tainer 25 Gallon Plastic Portable Utility Tank is a compact, white polyethylene flat-bottom utility tank with a 17 x 24 inch footprint and a 19-inch overall height, sized to move water and dilute liquids around a shop, barn, sprayer rig, or fleet wash bay without taking up a pallet of floor space. At 25 gallons, it lands in the size range people reach for when they search for a utility tank that holds real volume but still fits on a bench, a tailgate, or a small skid.
Will it work for what you're storing?
This is a 25-gallon tank measuring 24 inches long, 17 inches wide, and 19 inches tall, molded from polyethylene with a 1.5 specific gravity rating. Notice that it is wider and longer than it is tall: that low, broad stance gives it a low center of gravity, so it rides stable on a tailgate, trailer deck, or skid instead of wanting to tip. The 1.5 SG rating tells you the maximum density of liquid the wall is built to carry, up to 1.5 times the weight of water. Filled with plain water, the contents weigh about 208 lb; loaded to the full 1.5 SG rating, the tank is engineered to carry up to 313 lb of contents. Use both numbers when you plan where it sits. A surface that handles 208 lb of water will not necessarily handle 313 lb of a heavier liquid, so match the stand, shelf, or pad to the actual weight of what you intend to store. The flat-bottom format is meant to rest fully supported on a level surface, not to span gaps or hang from a frame.
Specs and what's in the box
Capacity is 25 gallons; dimensions are 24 in long x 17 in wide x 19 in tall, giving the 17.0 x 24.0 inch footprint to design your stand or shelf around. The body is white polyethylene with a 1.5 specific-gravity wall rating. This listing is for the bare tank: no fittings, bulkheads, or outlets are specified in this configuration, so confirm any openings you need against the technical drawing on this page before you plumb it or cut into it. Review that drawing for the full dimensional layout as well. If you are unsure whether 25 gallons covers your draw-down or refill cycle, the Tank Sizing Calculator and the Tank Sizing Guide walk through how to size by usage rather than by guesswork. If you plan to haul liquid on a farm or fleet rig, our guide to portable utility tanks and the 49 CFR 173.5 agricultural exemption covers the DOT transport context for that use.
One mistake to avoid
The 1.5 SG rating is the wall's structural ceiling, not a green light for any liquid. Specific gravity only addresses the weight the wall can hold; it says nothing about whether a given chemical attacks polyethylene. Treat this as a water and general-utility tank unless you have confirmed the specific liquid against the manufacturer's chemical-resistance data at your concentration and temperature. The most common error on a tank this size is overloading the support: people set it on a shelf rated for a 25-gallon water load, then fill it with something heavier and exceed either the 313 lb the wall is built for or the weight the shelf can bear. Plan the support for the heaviest contents you will ever put in it.
