The Norwesco 4035 Gallon Horizontal Elliptical Leg Tank in Blue is a transport-and-haul vessel molded from high-density linear polyethylene (HDLPE) and rated to a 1.9 specific gravity, the spec that lets this tank carry dense liquids most polyethylene tanks cannot. At 192 inches long, 92 inches wide, and 75 inches tall, it rides on integral legs that cradle the elliptical body for stable mobile and stationary haul service. This is one of the larger Norwesco horizontal leg tanks in the line, built for the bulk liquid moves that smaller pickup and trailer tanks cannot handle in a single trip.
Will this tank work for my load?
The decision starts with weight, not gallons. Filled with water this tank carries 33,652 pounds, and at its 1.9 specific gravity rating the maximum rated contents weight is 63,939 pounds. That number drives everything downstream: your trailer rating, axle count, suspension, and whether your tractor can legally and safely pull the load on the road. Run your intended fill level and liquid density through the Tank Sizing Calculator and review the Tank Sizing Guide before you commit a trailer to it. The 92 x 192 inch footprint and elliptical cross-section keep the center of gravity low for a tank this size, but a 4,035-gallon HDPE horizontal leg tank is a serious load and the running gear has to be matched to that 63,939 pound figure, not to the empty tank. Plan the install too: the empty tank arrives needing forklift or lifting gear to place, and the legs must sit on a flat, fully supported pad across the full 92 x 192 inch footprint.
Chemical compatibility
This is an HDLPE tank with a 1.9 specific gravity rating, which makes it a candidate for many dense agricultural and water-treatment liquids. Because the resin designation reads HDLPE without a confirmed crosslink, confirm HDLPE versus XLPE with us at 866-418-1777 before putting it into chemical service, since that distinction changes what the wall can tolerate over time. For the ag and fluid-handling buyers this leg tank is built for, the high-demand dense liquids are here: DEF at 32.5% requires 316SS fittings with EPDM gaskets (details) - note the metal fitting requirement, since the most common wrong order is specifying PVC for DEF - and Urea Solution at 50% takes PP/PVC fittings with EPDM gaskets (details). Always size your fittings and gaskets to the chemical, not to the tank.
Other chemicals from our chemical compatibility reference that pair with this resin and SG rating, with recommended fitting and gasket materials, include: Acetic Acid at 60% (details, PP/PVC fittings, EPDM gaskets); Aluminum Sulfate at 50% (details, PVC, EPDM); Calcium Chloride at 40% (details, PVC, EPDM); Ethylene Glycol at 100% (details, PVC, EPDM); Ferric Chloride at 50% (details, PVC, EPDM); Ferric Sulfate at 60% (details, PVC, EPDM); Ferrous Sulfate at 20% (details, PVC, EPDM); Hydrochloric Acid at 37% (details, PVC, Viton); Hydrofluoric Acid at 48% (details, PP/PVC, Viton); Hydrofluosilicic Acid at 26% (details, PP/PVC, Viton); Hydrogen Peroxide at 50% (details, PVC, Viton); Magnesium Chloride at 30% (details, PVC, EPDM); Peracetic Acid at 30% (details, 316SS, Aflas); Phosphoric Acid at 85% (details, PVC, Viton); Polyaluminum Chloride (details, PVC, EPDM); Potassium Carbonate at 50% (details, PVC, EPDM); Potassium Hydroxide, saturated (details, PVC, EPDM); Propylene Glycol (details, PP/316SS, EPDM); Sodium Bisulfate (details, PVC/PP, EPDM); Sodium Bisulfite (details, PVC/PP, EPDM); Sodium Carbonate at 30% (details, PVC, EPDM); Sodium Hypochlorite at under 16.5% (details, PVC, Viton); Sodium Thiosulfate at 40% (details, PVC, EPDM); Sulfuric Acid at 98% (details, CPVC, Viton); Zinc Orthophosphate (details, PP/316SS, EPDM); and Ozonated Water up to 10 PPM (PVC, EPDM - call 866-418-1777 to confirm). Every concentration and material recommendation is concentration- and temperature-specific, so verify your exact concentration and operating temperature against our reference before service.

The mistake to avoid
The error that bites buyers on a dense-liquid leg tank is matching fittings and gaskets to the tank instead of to the chemical. The HDLPE wall may handle a given acid while a standard EPDM gasket or PVC fitting will not, so the table above is the spec to build to, not an afterthought. The second mistake is treating the 1.9 SG rating as a license to fill with anything heavy: 1.9 SG is the structural ceiling for this polyethylene line, and any liquid denser than 1.9 SG requires a different, non-poly vessel. Within that ceiling, your trailer and the chemical reference still govern what actually goes in. For ag transport context, the Norwesco applicator and leg tank guide, the DOT classification breakdown for farm fleet use, and the fertilizer-blend stratification guide are worth reading before first fill. See the technical drawing on this page for the molded outlet and fitting layout.
This tank ships LTL freight, quoted live to your ZIP from the nearest Norwesco plant that stocks it - Fairfield, TX; Hanford, CA; Lancaster, OH; Philippi, WV; or St. Bonifacius, MN. On a tank this heavy, the freight delta between, say, the California and Ohio origin can swing your total more than the tank itself, so run a real number to your delivery ZIP with the Freight Cost Estimator before you compare list prices. Or call 866-418-1777 to confirm fittings, the HDLPE versus XLPE question, and the best shipping plant for your location.
