The Norwesco 3135 Gallon Horizontal Elliptical Leg Tank is an HDPE horizontal leg tank built for transporting and hauling liquids over the road and across the yard. Molded in blue High Density Linear Polyethylene with a 1.9 specific gravity rating, this 3135-gallon Norwesco horizontal tank measures 150 inches long, 88 inches wide, and 80 inches tall, with an 88.0 x 150.0 inch footprint that seats it on a saddle or skid frame for full elliptical support along its length.
Will it work for your load
This is a true workhorse leg tank, and the 1.9 SG rating is the number that matters most when you size your payload. Full of water the contents weigh roughly 26,146 lb, and the tank is rated to carry up to 49,677 lb of product at its maximum density. That headroom is what lets you run heavier fertilizer blends and dense chemicals without exceeding the resin rating. Before you load, confirm your liquid's specific gravity and back-calculate the gallons you can safely fill so you stay under both the tank rating and your trailer or chassis weight limits. Our Tank Sizing Calculator and Tank Sizing Guide walk through that math, and if you are spec'ing this for a fertilizer applicator or non-roadable trailer setup, the guide on Norwesco applicator and leg tanks for fertilizer explains DOT and NRT scope. For seasonal blend handling, the deep dive on fertilizer-blend tank stratification is worth reading before the spreader runs off-spec.
Chemical compatibility
This tank is molded in HDLPE and carries a 1.9 specific gravity rating, which is why it handles a long list of dense and aggressive chemistries. As a standing practice for chemical service, confirm HDLPE versus XLPE construction with us before committing to an aggressive chemical so the wall chemistry matches your liquid. Always verify against the OEM chemical-resistance chart for your exact concentration and temperature, since compatibility is concentration- and temperature-specific. Fittings are spec'd-to-order on this leg tank, so the chemistry-driven hardware is selected at order time rather than shipped as a fixed factory manifest. Match the gasket family to the chemical: EPDM is the default for most salts, glycols, DEF and carbonates; Viton handles the chlorinated and oxidizing acids (hydrochloric, sulfuric, phosphoric, hydrofluoric, hydrofluosilicic, hydrogen peroxide, sodium hypochlorite); and Aflas is called out for peracetic acid.
Within its rating this tank is listed compatible with acetic acid at 60%, aluminum sulfate at 50%, calcium chloride at 40%, DEF at 32.5%, ethylene glycol at 100%, ferric chloride at 50%, ferric sulfate at 60%, ferrous sulfate at 20%, hydrochloric acid at 37%, hydrofluoric acid at 48%, hydrofluosilicic acid at 26%, hydrogen peroxide at 50%, magnesium chloride at 30%, peracetic acid at 30%, phosphoric acid at 85%, polyaluminum chloride, potassium carbonate at 50%, potassium hydroxide (saturated), propylene glycol, sodium bisulfate, sodium bisulfite, sodium carbonate at 30%, sodium hypochlorite below 16.5%, sodium thiosulfate at 40%, sulfuric acid at 98%, urea solution at 50%, zinc orthophosphate, and ozonated water up to 10 PPM (verified by the OEM chart). Fitting materials run PVC, CPVC, PP, or 316 stainless depending on the chemistry: sulfuric acid at 98% calls for CPVC with Viton, DEF at 32.5% wants 316SS with EPDM, and peracetic acid at 30% needs 316SS with Aflas.

Freight and how to order
At roughly 88 inches wide and 150 inches long the tank exceeds a standard pallet and moves as oversize LTL freight on a flatbed or in an enclosed trailer, quoted live to your ZIP. Norwesco molds from several plants, so we route from the location nearest you to keep that oversize freight down: Griffin, GA; Lancaster, OH; Shawnee, OK; St. Bonifacius, MN; Tooele, UT; and Fairfield, TX. Get a real number with the Freight Cost Estimator, or call us at 866-418-1777 and we will quote the tank and freight together, line up the right fittings for your chemistry, and confirm lead time before you commit. See the technical drawing on this page for fitting locations and full dimensional detail.
