The Norwesco 2650 Gallon Heavy Duty Elliptical Leg Tank is built for one job: hauling dense liquids over the road and across the field without a stand. The light-blue polyethylene body sits low on its leg-tank profile (82 in tall, 88 in wide, 122 in long, an 88.0 x 122.0 in footprint) so the load stays stable in transit. What separates this unit from a standard storage tank is the 1.9 specific gravity rating, which is what makes it a true haul tank rather than a water-only vessel. If you have been searching for a Norwesco elliptical leg tank or an elliptical tank rated for weight, this is the size that carries it.
Will it handle my load?
At 2,650 gallons, plain water fills out to roughly 22,101 lb. Because this tank carries a 1.9 SG rating, it is approved for far denser liquids: the maximum rated contents weight is 41,992 lb. That headroom is the whole point of a 1.9-rated elliptical leg tank, where lighter-rated tanks would already be over their limit on the same volume of fertilizer or brine. Here is the lever to set before you fill: a 1.9 SG liquid fills the full 2,650 gallons right at the 41,992 lb ceiling, so for anything heavier than 1.9 SG you must short-fill to stay under that limit. At 1.9, this is the highest density rating offered in this elliptical leg-tank line, so there is no heavier-rated step-up tank to size into for your densest loads. Run your liquid's actual specific gravity against the 41,992 lb number, and use our Tank Sizing Calculator and Tank Sizing Guide to confirm the size fits your route and pump setup.
Chemical compatibility
This tank is polyethylene with a 1.9 SG rating; the exact resin grade is still being confirmed in our records (noted as HDLPE-pending). Confirm HDLPE versus XLPE before any chemical service, because crosslinked and linear polyethylene behave differently with aggressive liquids. The compatibility below is taken from our chemical compatibility data and is concentration- and temperature-specific, so verify your operating temperature against the OEM chart before committing. A simple gasket rule covers most of it: EPDM is the default, switch to Viton for the strong acids and oxidizers, and use Aflas specifically for peracetic acid. Watch the fitting metal too, since DEF and peracetic acid are the only two services here that call for 316SS fittings rather than PVC or PP. Suitable services include Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS fittings, EPDM), Ethylene Glycol (100%, PVC, EPDM), Ferric Chloride (50%, PVC, EPDM), Ferric Sulfate (60%, PVC, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Hydrochloric Acid (37%, PVC, Viton), Hydrofluoric Acid (48%, PP/PVC, Viton), Hydrofluosilicic Acid (26%, PP/PVC, Viton), Hydrogen Peroxide (50%, PVC, Viton), Magnesium Chloride (30%, PVC, EPDM), Peracetic Acid (30%, 316SS, Aflas), Phosphoric Acid (85%, PVC, Viton), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate (50%, PVC, EPDM), Potassium Hydroxide (saturated, PVC, EPDM), Propylene Glycol (PP/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), Sodium Carbonate (30%, PVC, EPDM), Sodium Hypochlorite (<16.5%, PVC, Viton), Sodium Thiosulfate (40%, PVC, EPDM), Sulfuric Acid (98%, CPVC, Viton), Urea Solution (50%, PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM).

The mistake to avoid
The costliest error on a 1.9-rated haul tank is filling on volume alone. A tank rated to 41,992 lb of contents will still fail axles, hitches, and pumps if you load 2,650 gallons of a liquid whose weight exceeds your trailer or chassis rating, even though the tank itself is within spec. Always run your liquid's actual specific gravity through the math, and pair the right fitting and gasket material to the chemical, since the wrong gasket is the most common cause of a leaking outlet on these units. Fitting configuration is selected to your service rather than fixed at the factory, so confirm outlet size, bulkhead, and vent before ordering and let the compatibility chart above set the correct fitting material for each chemical. If you are blending fertilizer, our guides on Norwesco applicator and leg tanks for fertilizer and fertilizer-blend tank stratification cover the field details, and the DOT classification guide for farm fleet use explains where the agricultural exemption applies.
This tank ships LTL freight and is stocked at three Norwesco plants, in Fairfield, TX, Lancaster, OH, and St. Bonifacius, MN, so southern and southwestern buyers can route from Texas to keep haul cost down. Freight is quoted live to your ZIP, so use our Freight Cost Estimator for a freight estimate or call 866-418-1777 and we will route it from the closest plant to you.
