The Norwesco 2035 Gallon HDPE Horizontal Elliptical Leg Tank in Blue is a transport-and-haul tank built for moving liquid down the road and across the field on a trailer or skid. The horizontal elliptical body sits low on integrated legs at 56 inches tall, 84 inches wide, and 142 inches long, giving it a stable 84.0 x 142.0 inch footprint that keeps the load down where it belongs when you are hauling. It is molded from high density linear polyethylene with a 1.9 specific gravity rating, which is what lets this tank carry dense agricultural and chemical liquids rather than just water. If you are shopping a norwesco horizontal leg tank or an HDPE horizontal tank for an applicator rig or a nurse trailer, this is that tank.
Will it work for your load and your trailer?
Run the weight and the dimensions before you build the trailer around it. Filled with plain water this tank holds roughly 16,972 pounds, and at its full 1.9 specific gravity rating it is engineered to carry up to 32,247 pounds of contents - nearly double the water figure. Those numbers drive your axle count, frame, and tie-down plan, so rate the chassis to the heavy figure if you ever intend to haul a dense fertilizer blend or chemical at full density. Just as important is fit: at 142 inches long and 84 inches wide, confirm your trailer deck is at least 11.9 feet long and 7 feet wide before ordering, because this body is too long to swing onto a short deck. Use the Tank Sizing Calculator and the Tank Sizing Guide to match capacity and weight to your job before you commit. Because this is a leg tank, mount it on a flat, fully supporting deck and strap it across the legs, not over the belly.
Chemical compatibility
This tank is molded from HDLPE and carries a 1.9 specific gravity rating, which is what makes it a candidate for chemical and fertilizer service rather than water alone. Compatibility always depends on concentration and temperature, so confirm your exact chemical against the OEM chemical-resistance chart before filling, and match the fitting and gasket materials below. One rule overrides everything else in this list: gasket choice is not interchangeable. Do not substitute EPDM where Viton or Aflas is specified - the wrong elastomer is the most common high-SG chemical-haul failure. And three loads override the PVC fitting default: sulfuric acid needs CPVC, while DEF and peracetic acid need 316SS.
- Acetic Acid (60%) - PP/PVC fittings, EPDM gasket
- Aluminum Sulfate (50%) - PVC fittings, EPDM gasket
- Calcium Chloride (40%) - PVC fittings, EPDM gasket
- DEF (32.5%) - 316SS fittings, EPDM gasket
- Ethylene Glycol (100%) - PVC fittings, EPDM gasket
- Ferric Chloride (50%) - PVC fittings, EPDM gasket
- Ferric Sulfate (60%) - PVC fittings, EPDM gasket
- Ferrous Sulfate (20%) - PVC fittings, EPDM gasket
- Hydrochloric Acid (37%) - PVC fittings, Viton gasket
- Hydrofluoric Acid (48%) - PP/PVC fittings, Viton gasket
- Hydrofluosilicic Acid (26%) - PP/PVC fittings, Viton gasket
- Hydrogen Peroxide (50%) - PVC fittings, Viton gasket
- Magnesium Chloride (30%) - PVC fittings, EPDM gasket
- Peracetic Acid (30%) - 316SS fittings, Aflas gasket
- Phosphoric Acid (85%) - PVC fittings, Viton gasket
- Polyaluminum Chloride - PVC fittings, EPDM gasket
- Potassium Carbonate (50%) - PVC fittings, EPDM gasket
- Potassium Hydroxide (saturated) - PVC fittings, EPDM gasket
- Propylene Glycol - PP/316SS fittings, EPDM gasket
- Sodium Bisulfate - PVC/PP fittings, EPDM gasket
- Sodium Bisulfite - PVC/PP fittings, EPDM gasket
- Sodium Carbonate (30%) - PVC fittings, EPDM gasket
- Sodium Hypochlorite (<16.5%) - PVC fittings, Viton gasket
- Sodium Thiosulfate (40%) - PVC fittings, EPDM gasket
- Sulfuric Acid (98%) - CPVC fittings, Viton gasket
- Urea Solution (50%) - PP/PVC fittings, EPDM gasket
- Zinc Orthophosphate - PP/316SS fittings, EPDM gasket
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gasket
Concentrations are listed because chemical resistance is concentration and temperature specific - a tank that handles dilute acid can fail at full strength. See the full chemical compatibility reference and the OEM chemical-resistance chart for any product you plan to store or haul.
The mistake to avoid
The trap on a high-SG leg tank is assuming the water weight is the number that matters. It is not. This tank is rated to 1.9 specific gravity, and a dense fertilizer or chemical load can push contents to about 32,247 pounds - build or rate your trailer to the contents weight, not the water weight, or you will overload axles and frame the first time you run something heavier than water. The second trap is hardware: this tank's fitting and outlet configuration is not pre-specified in our catalog data, so do not assume a standard lid, vent, or outlet ships with it. Call 866-418-1777 to confirm port, lid, and vent sizing for your application before you buy. For the regulatory side of hauling fertilizer on a non-roadable trailer, read our guides on applicator and leg tanks for fertilizer, portable utility tank DOT classification, and fertilizer-blend tank stratification.
This tank ships LTL freight, quoted live to your ZIP code from the nearest Norwesco plant - Fairfield, TX; Griffin, GA; Hanford, CA; Lancaster, OH; Shawnee, OK; St. Bonifacius, MN; or Tooele, UT. Because this is a large LTL load, your freight cost depends heavily on which of those seven plants ships it, so run your ZIP through the Freight Cost Estimator before comparing prices, or call 866-418-1777 to confirm the right tank, fittings, and delivery for your job.
