The Norwesco 1800 Gallon Horizontal Leg Tank is a polyethylene haul tank built for transport on a trailer or skid, where the long, low profile keeps the load stable down the road. It measures 146 inches long by 62 inches wide by 68 inches high, riding on a molded leg base with a 62.0 x 146.0 inch footprint. With a 1.5 specific gravity rating, this Norwesco horizontal leg tank in white carries water, fertilizer, and a range of agricultural and industrial liquids up to that density, and it is molded in Lancaster, Ohio.
Will it work for your load?
The 1800-gallon capacity translates to 15,012 pounds when filled with water. Because the tank is rated to a 1.5 specific gravity, it is engineered to hold up to 22,518 pounds of contents at full rated density. That sets a practical density ceiling: across the full 1,800 gallons, your contents should not exceed roughly 12.5 pounds per gallon to stay within the 22,518-pound rating. Use those numbers to check your trailer, suspension, and tongue weight before you fill it, because a liquid heavier than water reaches the tank's structural limit well before the tank is visually full. Size your load by weight, not by sight. The Tank Sizing Calculator and Tank Sizing Guide walk through that math for partial and full loads. For mounting, classification, and on-road use of horizontal and leg-style tanks, see our Norwesco applicator and leg tank guide and the portable utility tank DOT classification breakdown. Outlet, lid, and fitting configuration are not published in our spec record for this tank, so confirm those by phone before you order.
Chemical compatibility
This tank is polyethylene with a 1.5 specific gravity rating. The resin is recorded as HDLPE in our data but carries a query flag, so confirm whether your tank is HDLPE or XLPE with us before putting it into chemical service. Compatibility below is drawn from the OEM chemical-resistance chart and is concentration- and temperature-specific, so match your exact conditions to the chart before committing. Within the 1.5 SG rating, this tank handles acetic acid at 60%, aluminum sulfate at 50%, calcium chloride at 40%, DEF (diesel exhaust fluid) at 32.5% with 316 stainless fittings and EPDM gaskets, ferrous sulfate at 20%, magnesium chloride at 30%, sodium carbonate at 30%, urea solution at 50%, and ozonated water up to 10 PPM. Fitting and gasket materials vary by chemical: most use PVC fittings with EPDM gaskets, while acetic acid and urea use PP or PVC.
Chemicals that need a higher-SG tank
Several common liquids exceed what a 1.5 SG tank should hold and require a 1.9 specific gravity tank instead. If you are storing 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, or zinc orthophosphate, this 1.5 SG tank is the wrong choice and you should step up to a 1.9 SG model. Gasket selection tightens for the acids: hydrochloric, phosphoric, hydrogen peroxide, and sodium hypochlorite call for Viton, sulfuric needs CPVC fittings with Viton, and peracetic acid is the strictest, requiring 316 stainless fittings with an Aflas gasket. Cross-check every chemical against our full chemical compatibility reference before you order.
Freight
This tank ships LTL freight from the Norwesco plant in Lancaster, Ohio, quoted live to your ZIP code. Because it is a large horizontal leg tank, freight is priced by destination rather than included in the list price. Get a real number with our Freight Cost Estimator, or call 866-418-1777 and we will quote the haul from Lancaster to your delivery address, confirm HDLPE versus XLPE resin, and help you specify the right fittings for your contents.
