The Norwesco 335 Gallon Horizontal Elliptical Leg Tank in white is a self-supporting transport and nurse tank built for moving fertilizer blends and water-based chemicals around the farm or job site. Its low, wide elliptical profile keeps the center of gravity down when the tank is partially full and sloshing in transit, and the molded leg base lets it sit flat on a trailer deck or pickup bed without a separate cradle. Molded from polyethylene with a 1.5 specific gravity rating, this horizontal leg tank is sized for operations that need real haul capacity without stepping up to a full applicator trailer.
Will it work for your load?
The tank holds 335 gallons and measures 71 inches long, 48 inches wide, and 33 inches high, giving a 48.0 x 71.0 inch footprint to plan your deck or skid around. Water at 8.34 lb/gal puts a full load near 2,794 lb, and the 1.5 specific gravity rating supports contents up to roughly 4,191 lb total. That spread matters: water and most fertilizer solutions live well inside the rating, but the heavier the liquid, the closer you ride to the ceiling, so size the contents weight against the 1.5 SG limit before you fill. Full dimensions and the molded outlet detail are shown on the technical drawing on this page. If you are not sure this is the right capacity for your tow vehicle or spray program, run the numbers through our Tank Sizing Calculator and review the Tank Sizing Guide.
Chemical compatibility
This tank is molded in polyethylene with a 1.5 specific gravity rating. Confirm the exact resin of your unit before putting it into chemical service, since cross-linked resin behaves differently from linear resin with some products. At the 1.5 SG rating, this tank is compatible with acetic acid (60%), aluminum sulfate (50%), calcium chloride (40%), DEF (32.5%), ferrous sulfate (20%), magnesium chloride (30%), sodium carbonate (30%), urea solution (50%), and ozonated water (up to 10 PPM). DEF (32.5% urea) carriers can run this tank, but only with 316 stainless fittings and EPDM gaskets. Most of the other listed chemicals run PVC fittings with EPDM gaskets, while acetic acid and urea solution call for PP or PVC. Ozonated water service should be confirmed by phone, since concentration and contact time drive the pairing. Always verify against the manufacturer's chemical-resistance chart at your exact concentration and temperature.
Before you order, run the SG check: if your program includes any acid (sulfuric, hydrochloric, phosphoric, hydrofluoric), sodium hypochlorite, or a glycol, this 1.5 SG tank is the wrong tool and you should order the 1.9 SG equivalent instead. The chemicals that exceed this tank's 1.5 SG rating and need a higher 1.9 SG tank are 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. Start with our full chemical compatibility reference to confirm resin, fitting, and gasket pairings.
The mistake to avoid
The biggest error with a leg tank like this is filling it with a liquid heavier than its rating supports. The 1.5 SG ceiling is a structural limit, not a suggestion, and overloading a denser product shortens wall life and can fail the tank in transit. The second is gasket and fitting mismatch. Use PVC fittings with EPDM gaskets as the default; switch to Viton gaskets for sodium hypochlorite, hydrochloric acid, hydrogen peroxide, sulfuric acid, and phosphoric acid; use Aflas for peracetic acid; and run 316 stainless fittings for DEF and peracetic acid. Do not reuse a generic EPDM-and-PVC kit across every chemical, and never put brass or zinc fittings on a DEF tank. For the DOT and agricultural-exemption side of hauling fertilizer in a leg tank, our guides on applicator and leg tanks for fertilizer and fertilizer-blend stratification cover the field details that catch operators off guard.
This Norwesco leg tank ships LTL freight, quoted live to your ZIP from the nearest stocking plant in Hanford, CA, Lancaster, OH, or Shawnee, OK. Its low, wide 71 x 48 inch footprint drives the LTL rate, so pull a ZIP quote from the nearest of those three plants before you compare it to any "free shipping" listing elsewhere.
