The Norwesco 2035 Gallon Horizontal Elliptical Leg Tank is a white polyethylene horizontal leg tank built for nurse-rig and applicator-style hauling where the tank needs a low, wide stance and a self-supporting molded cradle. It carries 2,035 gallons, stands 56 inches tall, and rides on an 84-inch wide by 142-inch long elliptical footprint, so it sits low on a trailer or skid and keeps the center of gravity down when full. This is a Norwesco horizontal leg tank rated to 1.5 specific gravity, which is the number that decides what you can legally and safely put in it.
Will it work for your load
The geometry and the weights are what matter here. Filled with plain water the contents alone weigh 16,972 pounds; loaded to the full 1.5 specific gravity the tank is rated for, contents can reach 25,458 pounds. Run those numbers against your trailer, axle ratings, and any DOT classification for your fleet before you build the rig - a horizontal leg tank this size is a structural decision, not just a volume decision. Use the Tank Sizing Calculator and the Tank Sizing Guide to match capacity to your towing setup, and review the technical drawing on this page for the molded leg layout and fitting locations. Fittings on a tank this size are configured per order, so call us at 866-418-1777 to confirm the outlet, vent, and fill package for your application before you commit. If you are spec'ing this for fertilizer or a non-roadable trailer, our guides on Norwesco applicator and leg tanks for fertilizer and portable utility tank DOT classification walk through the scope and exemptions.
Chemical compatibility
This tank is polyethylene rated to 1.5 specific gravity. At the 1.5 rating, the following are compatible per the manufacturer's chemical-resistance chart, which is concentration- and temperature-specific, so verify your exact conditions against it before filling: Acetic Acid at 60% (PP/PVC fittings, EPDM gaskets), Aluminum Sulfate at 50% (PVC, EPDM), Calcium Chloride at 40% (PVC, EPDM), DEF at 32.5% concentration (316SS fittings, EPDM gaskets), Ferrous Sulfate at 20% (PVC, EPDM), Magnesium Chloride at 30% (PVC, EPDM), Sodium Carbonate at 30% (PVC, EPDM), Urea Solution at 50% (PP/PVC, EPDM), and Ozonated Water up to 10 PPM (PVC, EPDM). DEF is a common haul for a tank this size; for blended loads, read our guide on fertilizer-blend tank stratification before it costs you a run off-spec. See the full chemical compatibility tool for fitting and gasket pairings.
The mistake to avoid
The most expensive error on a tank like this is overrunning the specific-gravity rating. At 1.5 SG this tank tolerates a product up to 1.5 times the density of water - that is the 25,458-pound contents ceiling against 16,972 pounds for plain water. Anything denser exceeds the wall rating and becomes a structural failure risk, not just a chemical one. Heavier chemistries need a 1.9 SG tank, not this one, and several of them also need a different fitting and gasket package - Viton or Aflas gaskets and harder fitting materials like CPVC or 316SS - so the step up is a full-spec change, not a one-line swap. That 1.9-SG list includes 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. When in doubt, call us before you fill.
Freight
This tank is stocked at seven Norwesco plants coast to coast - Fairfield, TX; Griffin, GA; Hanford, CA; Lancaster, OH; Shawnee, OK; St. Bonifacius, MN; and Tooele, UT - so we ship LTL from the one nearest your ZIP, which keeps your freight cost down on a load this heavy.
