The Norwesco 235 Gallon Horizontal Elliptical Leg Tank (N-44806) is a white polyethylene leg tank built for transport and field use, with integral support legs that let it ride flat on a trailer, skid, or truck bed without a separate cradle. It measures 32 inches high by 40 inches wide by 66 inches long, putting a 40-by-66-inch footprint under the load. Filled with water it carries roughly 1,960 pounds, and Norwesco rates it to a maximum contents weight of about 2,940 pounds at its 1.5 specific gravity ceiling. Because Norwesco molds this tank at four plants - Hanford, CA; Lancaster, OH; Shawnee, OK; and Sheldon, IA - freight ships from whichever plant is closest to your ZIP, which is exactly why operators searching for a Norwesco horizontal tank for an applicator rig or nurse setup tend to land here.
Will it work for your job?
This is a 235-gallon horizontal tank with threads for an 8-inch cap as the primary opening, per the technical drawing on this page. Plan your plumbing around that single top opening: it is the fill and access point, and any outlet, vent, or siphon hardware mounts through it. The 1.5 specific gravity rating is the number that decides whether your liquid is in bounds - multiply your product's specific gravity by 235 gallons (about 8.34 pounds per gallon of water) and confirm the contents weight stays under 2,940 pounds. Plain water (SG 1.0) fills it to roughly 1,960 pounds with margin to spare. A heavier ag liquid eats that headroom fast: Calcium Chloride at 40% runs near SG 1.4, so a full load lands around 2,740 pounds - still legal, but close to the wall. Use the Tank Sizing Calculator and the Tank Sizing Guide to match capacity and weight to your trailer or spreader. For DOT and agricultural-exemption questions on hauling fertilizer in a leg tank, see our guides on Norwesco applicator and leg tanks for fertilizer and portable utility tanks under 49 CFR 173.5.
Chemical compatibility
This Norwesco tank is polyethylene rated to 1.5 specific gravity. The exact resin grade is not confirmed in our records, so confirm whether your unit is HDLPE or XLPE before putting it into chemical service - that distinction changes which products it will hold safely. At the 1.5 rating, the following are within range when paired with the right fittings and gaskets, per the OEM chemical-resistance chart, 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), 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). DEF at 32.5% makes this a workable nurse tank for diesel exhaust fluid: a full load stays comfortably inside the weight ceiling when fitted with 316 stainless hardware - confirm your exact product and storage temperature first.
Some chemicals do not belong in a 1.5-rated tank and require a higher 1.9 specific gravity Norwesco tank instead - an honest call before you commit: 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. Always verify your exact product, concentration, and temperature against the chemical compatibility reference before ordering.
The mistake to avoid
The most common error on this tank is treating the 1.5 specific gravity rating as a suggestion. It is the wall: heavier liquids like sodium hypochlorite or sulfuric acid need the 1.9-rated version, and running them here shortens the tank's life. Run a three-step pre-fill check every time: (1) confirm the resin - HDLPE or XLPE - for chemical service; (2) confirm specific gravity times 235 gallons stays under 2,940 pounds; and (3) match the fitting and gasket to the specific chemical, not just the tank. DEF wants 316 stainless with EPDM, sulfuric acid runs on CPVC with Viton, several of the 1.9-list acids call for Viton gaskets, and most ag salts run fine on PVC with EPDM through that single 8-inch cap opening.
