The Norwesco 2650 Gallon Black Elliptical Leg Tank is a transport-built polyethylene vessel for moving water, fertilizer, and compatible solutions across the farm or down the road. It carries a true 2,650-gallon capacity in a UV-stabilized black polyethylene shell with a 1.5 specific gravity rating, so it is engineered to haul liquids heavier than water without deforming. The elliptical leg-tank profile keeps the load low and stable on a trailer, which is exactly what an applicator or nurse-tank operator needs when the rig is full and rolling.
Will it work for your job
This is a haul tank, and the weight math is what decides whether your trailer and pump are sized right. The body measures 82 in high, 88 in wide, and 122 in long, sitting on an 88.0 x 122.0 in footprint. Filled with water the contents alone weigh 22,101 lb; loaded to the full 1.5 SG rating the tank holds up to 33,152 lb of liquid. That jump from a water load to a full 1.5-SG load is about 11,000 lb, so size your axles, hitch, and tie-downs around the 33,152 lb figure, never the empty shell or the water number. The 1.5 specific gravity rating is the headline number here: it is what lets this Norwesco leg tank carry dense fertilizer blends and brines that a standard 1.0 or 1.1 SG water tank should never see. For matching gallons to your acreage and application rate, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you commit. See the technical drawing on this page for the dimensional and outlet layout. If you are spec'ing for fertilizer service specifically, our guide on Norwesco applicator and leg tanks for fertilizer walks through DOT non-roadable-trailer scope, the companion piece on portable utility tanks and the 49 CFR 173.5 agricultural exemption covers farm-fleet classification, and our deep dive on fertilizer-blend tank stratification covers how dense blends layer and salt out in a tank this size.
Chemical compatibility
This tank is molded from polyethylene with a 1.5 specific gravity rating. Before you put any chemical in it, confirm your unit's resin type for the specific chemical service you intend. At the 1.5 SG rating, the following are listed compatible in our chemical compatibility reference, which is concentration- and temperature-specific: Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS fittings, EPDM gaskets), 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, EPDM). Note that DEF specifically requires 316SS stainless fittings, not PVC or PP, so match it exactly. Always verify at your actual concentration and temperature, and match every fitting and gasket material as listed.
Chemicals that need a higher-SG tank
Several common chemicals exceed what a 1.5 SG tank should hold and require a 1.9 specific gravity tank instead. Do not run these in this unit: Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrochloric Acid, Hydrofluoric Acid, Hydrofluosilicic Acid, Hydrogen Peroxide, Peracetic Acid, Phosphoric Acid, Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Hypochlorite, Sodium Thiosulfate, Sulfuric Acid, and Zinc Orthophosphate. We stock 1.9-SG tanks for exactly these services, so call us at 866-418-1777 and we will match a 1.9-SG tank to your chemical, fitting, and gasket spec. Full details for every chemical live on our chemical compatibility reference.
The mistake to avoid
The single most costly error on a tank this large is treating the specific gravity rating as a suggestion. This is a 1.5 SG tank: it will carry water, urea, DEF, and the compatible fertilizer chemicals above, but the moment you load a 1.9-density product into it you are risking a wall failure with 33,152 lb of liquid in motion. Confirm your product's specific gravity, confirm your resin type, and match every fitting and gasket to the listed compatibility data.
