The Norwesco 6025 Gallon Horizontal Leg Tank is one of the largest haul-format tanks Norwesco molds, and before its capacity sells you, run the weight math: filled with water it carries roughly 50,248 lb of contents, and at its full 1.5 specific gravity wall rating it is engineered to hold up to 75,373 lb of product. That contents weight alone exceeds what a single standard LTL shipment handles casually, so confirm your delivery site can receive a heavy LTL freight delivery before you order. Molded in white polyethylene as a low-slung horizontal leg tank, it keeps a dense load low and stable for nurse-trailer and skid transport.
Will this tank work for your load?
The horizontal leg-tank format is why operators reach for this Norwesco horizontal tank for fertilizer and water hauling - the load sits low and stays planted in transit. The 1.5 SG rating means the wall is designed for products up to 1.5 specific gravity; run anything denser and you are outside the design. The real spec discipline here is matching full-load weight to your equipment: near 50,000 lb with water, and over 75,000 lb at the full 1.5 SG rating. Match that against your trailer, axle, and tie-down capacity before you fill. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm your fill weight against your hauling setup.

Chemical compatibility
This tank is polyethylene at a 1.5 SG wall rating. The resin type is being verified - do not commit to any chemical service until we confirm linear (HDLPE) versus crosslinked (XLPE) by SKU, because the two differ materially in chemical resistance. With that confirmation in hand, and checked against your exact concentration and operating temperature, the following are compatible at the 1.5 SG rating per our chemical-resistance data: Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Magnesium Chloride (30%, PVC, EPDM), Sodium Carbonate (30%, PVC, EPDM), Urea Solution (50%, PP/PVC, EPDM), and Ozonated Water (up to 10 PPM, PVC fittings, EPDM gaskets). The OEM chemical-resistance chart is concentration- and temperature-specific, so verify your exact service conditions; see our full chemical compatibility resource.
Hauling denser products? Spec a 1.9 SG tank
Several products commonly run in leg tanks exceed the 1.5 SG wall rating and require a 1.9 SG-rated Norwesco horizontal tank instead - that is the correct purchase for them, not this tank. Those include Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrochloric Acid (PVC, Viton gaskets), Hydrofluoric Acid (PP/PVC, Viton), Hydrofluosilicic Acid, Hydrogen Peroxide (PVC, Viton), Peracetic Acid (316SS, Aflas), Phosphoric Acid (PVC, Viton), Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Hypochlorite (PVC, Viton), Sodium Thiosulfate, Sulfuric Acid (CPVC, Viton), and Zinc Orthophosphate. Spec the higher-SG tank with the matching fitting and gasket materials - Viton for the acids and hypochlorite, Aflas for peracetic acid. For the regulatory and field side of fertilizer hauling, our guides on Norwesco applicator and leg tanks for fertilizer, DOT classification for farm-fleet use, and fertilizer-blend tank stratification walk through density, mixing, and field verification.
This tank ships LTL freight from the nearest Norwesco plant - Lancaster, OH or St. Bonifacius, MN - and freight is quoted live from whichever plant is closer to your ZIP, so an Ohio buyer and a Minnesota buyer see very different numbers. Get a real number in seconds with the Freight Cost Estimator, or call 866-418-1777 to route your shipment. Given the size and contents weight of this tank, confirm your delivery site can receive a heavy LTL freight delivery before you order.
