The Norwesco 1335 Gallon HDPE Horizontal Elliptical Leg Tank in blue is a transport-and-store workhorse for liquid fertilizer, water hauling, and chemical service on a truck bed or applicator trailer. Built from high density linear polyethylene with a 1.9 specific gravity rating, this horizontal leg tank carries a 1,335-gallon working volume in a low, stable profile: 55 inches tall, 66 inches wide, and 126 inches long. The integrated leg-tank floor sits flat on a deck so the tank rides square and drains toward the outlet, which is what makes a horizontal leg tank the standard choice for nurse-tank and applicator duty.
Will it work for your load
The 1.9 SG rating is the number that matters here. Filled with plain water the tank holds roughly 11,134 pounds; loaded to its full 1.9 specific gravity rating it is engineered for contents up to about 21,154 pounds. That headroom is why this HDPE tank handles dense liquid fertilizers and many concentrated chemicals that would overstress a 1.0 or 1.5 SG tank. Match your filled contents weight to your trailer or truck-bed rating before you load, and use the Tank Sizing Calculator and Tank Sizing Guide to confirm the 66 x 126 inch footprint fits your frame. See the technical drawing on this page for outlet and fitting callouts.
Chemical compatibility
This tank is high density linear polyethylene (HDLPE) with a 1.9 specific gravity rating, so it is rated for a wide range of dense and aggressive liquids. Compatibility always depends on concentration and temperature, so verify your exact chemical against the OEM chemical-resistance chart before service, and match your fittings and gaskets to the chemical as well as the tank. Fertilizer and ag-applicator buyers will care about urea solution (50%) with PP/PVC fittings and EPDM gaskets, DEF (32.5%) with 316 stainless steel fittings and EPDM gaskets, and water-treatment salts like aluminum sulfate (50%), calcium chloride (40%), and magnesium chloride (30%) on PVC and EPDM. The shell also handles aggressive acids and oxidizers at the right fitting spec: sulfuric acid (98%) with CPVC and Viton, hydrochloric acid (37%) with PVC and Viton, phosphoric acid (85%) with PVC and Viton, ferric chloride (50%) with PVC and EPDM, sodium hypochlorite (under 16.5%) with PVC and Viton, and hydrogen peroxide (50%) with PVC and Viton. Stronger acids such as hydrofluoric (48%) and hydrofluosilicic (26%) need Viton gaskets, and peracetic acid (30%) calls for 316SS fittings with Aflas gaskets. Glycols including ethylene glycol (100%) and propylene glycol are also covered. The fitting and gasket material is as important as the resin, so confirm both, concentration- and temperature-specific, before you plumb. Start at the chemical compatibility tool to check your specific liquid.
The mistake to avoid
The most common error on a tank like this is fitting material, not the tank itself. The HDLPE shell handles the chemical, but the fittings and gaskets are where field failures actually happen. Three chemicals in our compatibility data specifically demand metal rather than plastic at the bulkhead: DEF and peracetic acid both call for 316 stainless steel, and zinc orthophosphate takes PP or 316SS. Plumb DEF with PVC, or run sodium hypochlorite, hydrogen peroxide, or sulfuric acid on EPDM instead of Viton, and you risk failure at the gasket and bulkhead long before the tank ever shows wear. Spec your fittings and gaskets per the OEM chemical-resistance chart for the exact chemical and concentration you are running, then confirm outlet location and fitting positions against the technical drawing on this page before you finalize a plumbing layout.
This 1335 gallon Norwesco horizontal leg tank ships empty on a pallet via LTL freight, quoted live to your ZIP — the 11,134 lb full-water and 21,154 lb full-rated figures are in-service loads, not freight weight. It ships from the nearest stocking plant: Eastern and Southeastern buyers pull from Lancaster, OH, while Upper-Midwest and Plains buyers ship from St. Bonifacius, MN, which materially changes the LTL cost.
