The Norwesco 5025 Gallon Black Heavy Duty Horizontal Leg Tank is built for operations that haul large fertilizer and liquid loads over the road. With a rated 5,025-gallon capacity, a 1.9 specific gravity rating, and a black UV-resistant polyethylene shell, this horizontal leg tank carries the cradle-style footprint that applicators and bulk handlers rely on. It measures 190 inches long, 92 inches wide, and 96 inches tall, with a 92.0 x 190.0 inch footprint that sets the saddle-supported geometry you'll need to match to a frame, skid, or non-roadable trailer.
Will this tank work for your load?
Sizing is everything on a tank this size, and the pack gives you two bracket numbers to design around. Filled with plain water (specific gravity 1.0), the contents alone weigh roughly 41,908 lb. At the full 1.9 SG rating, the tank is built to carry up to about 79,626 lb of product. Treat those as your light-product minimum and max-density ceiling: every trailer rating, axle count, and support cradle decision lives between them, so confirm both against your chassis before you order. The black polyethylene construction holds up to sunlight in open-yard and field service, and the horizontal leg geometry keeps the load low and stable for transport. Run your light and heavy loads through the Tank Sizing Calculator and the Tank Sizing Guide before you commit to a frame. See the technical drawing on this page for outlet and fitting locations before you plumb it.
Chemical compatibility
This tank carries a 1.9 specific gravity rating, which is what makes it suitable for dense chemical solutions, not just water. The resin designation in our records is unconfirmed, so confirm whether your unit is HDLPE or XLPE before putting it into chemical service, since that distinction changes what it can safely hold and is independent of the SG rating. Compatibility is always concentration- and temperature-specific, so check the OEM chemical-resistance chart for the exact product and strength you plan to store. Within the 1.9 SG rating, this tank is referenced for a wide range of chemistries, including Sulfuric Acid at 98% (CPVC fittings, Viton gaskets), Phosphoric Acid at 85% (PVC, Viton), Hydrochloric Acid at 37% (PVC, Viton), Hydrofluoric Acid at 48% (PP/PVC, Viton), Ferric Chloride at 50% (PVC, EPDM), Aluminum Sulfate at 50% (PVC, EPDM), Sodium Hypochlorite below 16.5% (PVC, Viton), Hydrogen Peroxide at 50% (PVC, Viton), Calcium Chloride at 40% (PVC, EPDM), DEF at 32.5% (316 stainless fittings, EPDM), Urea Solution at 50% (PP/PVC, EPDM), Ethylene Glycol at 100% (PVC, EPDM), and Peracetic Acid at 30% (316 stainless, Aflas). It is also referenced for Sodium Bisulfite, Potassium Hydroxide (saturated), Polyaluminum Chloride, and Ozonated Water up to 10 PPM (PVC, EPDM), among others. As a quick at-a-glance rule from the data: reach for Viton gaskets on the oxidizers and strong acids (sulfuric, phosphoric, hydrochloric, hydrofluoric, hydrogen peroxide, sodium hypochlorite), EPDM on the salts, glycols, DEF, and urea, and the specialty Aflas with 316 stainless for peracetic acid.

The mistake to avoid
The two most common errors on a heavy-duty leg tank this size are mismatching the fitting and gasket materials to the chemical, and assuming "polyethylene is polyethylene." A Viton gasket is called out for oxidizers and strong acids like sulfuric, phosphoric, hydrochloric, and sodium hypochlorite, while EPDM works for the salts and glycols; using the wrong elastomer is how connections fail. And because the resin grade in our records is unconfirmed (HDLPE vs XLPE), verify it against the technical drawing and OEM chart on this page before storing anything aggressive. For straight water or non-aggressive fertilizer blends, none of that applies, but it matters the moment you move to chemical service.
This Norwesco horizontal leg tank ships LTL freight, quoted live to your ZIP from the nearest of two Norwesco plants, St. Bonifacius, MN or Washington Court House, OH, so an eastern buyer is priced off Ohio rather than Minnesota. Get an exact freight number with the Freight Cost Estimator, or call us at 866-418-1777 to talk through trailer fit, fitting layout, and chemical service.
