The Norwesco 3250 Gallon Horizontal Leg Tank is a high-volume, transport-ready vessel molded from high-density linear polyethylene (HDLPE) in blue, carrying a 1.9 specific gravity rating that puts it firmly in the heavy-chemical and concentrated-fertilizer class. At 152 inches long, 88 inches wide, and 82 inches tall, this elliptical leg tank rides low and stable on its integral support legs, the standard Norwesco design for skid-mount and trailer-mount field use. Whether you are searching for a Norwesco horizontal leg tank, an HDPE horizontal tank, or simply a large leg tank, this is one of the biggest single-vessel options in the line.
Will it work for your application?
Capacity is 3,250 gallons. A full load of water weighs roughly 27,105 pounds, while the tank carries a maximum rated contents weight of 51,500 pounds at its 1.9 specific gravity rating, and that second number is what governs how heavy a product you can safely fill it with. The math is your go/no-go check: your contents specific gravity multiplied by 27,105 pounds must stay under the 51,500-pound ceiling. At 1.9 SG the tank fills to capacity right as it reaches that weight limit, so this is genuinely a heavy-product tank rather than a water tank that happens to be large. Before you spec a trailer, frame, or skid, run that calc, then confirm your support structure and axles can carry it. The footprint is 88.0 x 152.0 inches, so plan your mounting cradle and saddle spacing to match the elliptical contour. The Tank Sizing Calculator and our Tank Sizing Guide help you check fill weight against your equipment before you buy.
Chemical compatibility
This is an HDLPE shell rated to 1.9 specific gravity, which is what makes it a workhorse for dense, aggressive products. Always size your chemical's specific gravity against the 1.9 rating, and match the wetted fittings and gaskets to the product. Most chemicals below run on PVC fittings with an EPDM gasket, but watch the exceptions: several aggressive oxidizers and acids need Viton gaskets, peracetic acid needs Aflas, and DEF, peracetic acid, propylene glycol, and zinc orthophosphate call for 316 stainless wetted fittings. Compatibility is concentration- and temperature-specific, so verify your exact product against the OEM chemical-resistance chart, not the generic chemical name.

One expensive mistake on a tank this size is assuming the HDLPE shell handles every chemical equally. It does not. No fittings are pre-installed; wetted fitting and gasket materials are selected per chemical and confirmed at order, so match the materials above to your exact product and call 866-418-1777 if you want help configuring an outlet. See the full reference at our chemical compatibility center.
The mistake to avoid
Confirm the resin family before chemical service. This shell is HDLPE, and different polyethylene resin types can behave differently with certain oxidizers and solvents, so verify the resin requirement for your product before you fill. Just as important, do not under-spec your mount: the combination of the 51,500-pound rated contents weight and the long 152-inch elliptical body means saddle support and weight distribution are not optional details. If this is a fertilizer or applicator build, our guides on Norwesco applicator and leg tanks for fertilizer and on fertilizer-blend tank stratification walk through DOT scope and the mixing physics that catch problems before the spreader runs off-spec. For dimensional detail, see the technical drawing on this page.
