The Norwesco 750 Gallon Horizontal Elliptical Cradle Tank in white is a haul-and-store polyethylene tank built for the field: an elliptical cross-section that sits low in its integral cradle so the load stays stable in transport and the tank drains toward the 2" outlet. It holds 750 gallons, weighs 219 lb empty, and measures 88" long by 69" wide by 48" high with a 16" lid for fill and inspection. The 1.5 specific gravity rating is the number that decides whether this tank is right for your product, so read the sizing and chemical sections below before you buy. Growers and haulers searching for a 750 gallon Norwesco horizontal elliptical cradle tank land here for exactly that reason.
Will it work for your load?
Full of water this tank carries about 6,255 lb; at its maximum 1.5 specific gravity rating it is rated to roughly 9,382 lb of contents. Add the 219 lb empty shell and a fully loaded 1.5-SG tank grosses around 9,601 lb — that is the number to spec your trailer, skid deck, and axle rating against, not the empty weight. That spread is the whole point of a 1.5-rated tank: it is engineered to haul liquids heavier than water. The footprint is 69.0 x 88.0 inches. Norwesco molds this tank with a 2" outlet and a 16" lid, and it carries an FDA-approved rating and a 120 F / 48 C maximum operating temperature. If you are matching gallons to a spray schedule or a nurse-tank rotation, run the numbers through the Tank Sizing Calculator or the Tank Sizing Guide first.
Chemical compatibility
This is a polyethylene tank rated to 1.5 specific gravity. The resin is listed as HDLPE but not confirmed here, so before any chemical service confirm HDLPE versus XLPE with us at 866-418-1777 — the two crosslink differently and that changes what you can store. Compatibility below is drawn from the Snyder Industries OEM chemical-resistance chart and is concentration- and temperature-specific; confirm your exact chemical, concentration, temperature, and fitting and gasket materials before filling.
Chemicals this 1.5-rated tank handles at the listed concentrations include acetic acid (60%), aluminum sulfate (50%), calcium chloride (40%), DEF (32.5%), ferrous sulfate (20%), magnesium chloride (30%), sodium carbonate (30%), urea solution (50%), and ozonated water up to 10 PPM. Most call for PVC or PP fittings with EPDM gaskets; DEF specifies 316SS fittings with EPDM. Note that DEF and urea solution only require a 1.35 SG rating, so this 1.5 tank sits comfortably over-specced for those fluids — useful headroom if you rotate products. Verify each against the OEM chart for your service temperature.
Some products need a heavier tank than this one. Ethylene glycol, ferric chloride (50%), ferric sulfate (60%), hydrochloric acid (37%), hydrofluoric acid (48%), hydrofluosilicic acid (26%), hydrogen peroxide (50%), peracetic acid (30%), phosphoric acid (85%), polyaluminum chloride, potassium carbonate/hydroxide, sodium hypochlorite (<16.5%), and sulfuric acid (98%) all require a 1.9-rated tank — do not store them in this 1.5 tank. Several also step up the seal material: most need Viton rather than EPDM, sulfuric acid needs CPVC fittings, and peracetic acid needs 316SS fittings with Aflas gaskets. Check the full chemical compatibility tool for your match, or call 866-418-1777 for a 1.9-rated equivalent.
The mistake to avoid
The trap on a 1.5-rated elliptical cradle tank is loading a heavier chemical than the rating allows — a fluid over 1.5 specific gravity, or one of the acids above that needs a 1.9 tank, will overstress the wall over time even though it "fits" the gallons. Spec the tank to the density and the chemistry, not just the volume, and match the seal material to the fluid. And confirm the HDLPE-versus-XLPE resin question before committing to any chemical program.
