Norwesco 65 Gallon Horizontal Leg Tank in White

The Norwesco 65 Gallon Horizontal Leg Tank in white is a polyethylene haul-and-transport tank built for mobile field work, where the molded support legs keep the load stable on a trailer, truck bed, or skid.Rated to a 1.5 specific gravity, this 65-gallon Norwesco horizontal tank handles water and a useful range of ag and treatment chemicals up to that density, making it a practical choice for the kind of nurse-tank, applicator, and utility hauling that buyers searching for a "horizontal leg tank" are usually solving for.

Will this tank work for your job?

Start with weight, not gallons.Filled with plain water this tank carries about 542 lb of contents, and at its full 1.5 SG rating it is built to hold up to roughly 813 lb of contents.Size your trailer, hitch, and tie-downs against the heavier number if you plan to haul anything denser than water, and confirm your axle and tongue-weight ratings before the first loaded run.The lid uses a threaded fitting (see the technical drawing on this page for the lid thread detail and the exact fitting layout).For help converting your load into the right capacity, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide.

Chemical compatibility

This is an HDLPE polyethylene tank with a 1.5 specific gravity rating.The resin grade is not fully confirmed in our source data, so confirm HDLPE versus XLPE before putting any chemical into service — the two resins behave differently and the wrong one can fail early.At the 1.5 SG rating, this tank is suited to the following solutions, always paired with the correct fitting and gasket hardware: Acetic Acid at 60% (PP/PVC fittings, EPDM gaskets), Aluminum Sulfate at 50% (PVC, EPDM), Calcium Chloride at 40% (PVC, EPDM), DEF at 32.5% (316SS, EPDM), Ferrous Sulfate at 20% (PVC, EPDM), Magnesium Chloride at 30% (PVC, EPDM), Sodium Carbonate at 30% (PVC, EPDM), Urea Solution at 50% (PP/PVC, EPDM), and Ozonated Water up to 10 PPM (PVC, EPDM).One thing to flag: DEF (diesel exhaust fluid) is the exception to the PVC pattern here — it calls for 316 stainless fittings, not PVC, so a DEF hauler should not default to plastic hardware.Verify every chemical against the OEM chemical-resistance chart for your exact concentration and temperature before filling, and see our chemical compatibility reference for the full picture.

The mistake to avoid: don't overrun the SG rating

The most common error on a leg tank like this is loading a chemical denser than what a 1.5 SG tank is built for.Several common treatment and ag chemicals exceed that and require a higher-SG (1.9) tank instead — including 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, and Zinc Orthophosphate.Match the gasket to the chemical, too: most of these run PVC fittings with EPDM, but the oxidizers and strong acids — Hydrochloric, Hydrofluoric, Hydrofluosilicic, Hydrogen Peroxide, Phosphoric, Sodium Hypochlorite, and Sulfuric (CPVC for Sulfuric) — call for Viton gaskets, and Peracetic Acid needs Aflas with 316SS.If your chemical is on this 1.9 list, this tank is simply the wrong rating — call 866-418-1777 or ask us about our 1.5 SG horizontal and leg tanks so you buy the right wall thickness the first time.If you are blending fertilizer, our guide on fertilizer-blend tank stratification covers the mixing and verification steps that catch a stratified load before it runs off-spec.

Hauling, DOT scope, and freight

Because this is a mobile leg tank, the DOT side matters as much as the chemistry.Our writeups on Norwesco applicator and leg tanks for fertilizer and portable utility tanks under the 49 CFR 173.5 agricultural exemption explain the non-roadable-trailer scope and farm-fleet classification before you put a loaded tank on the road; if your plan involves anhydrous, read the 29 CFR 1910.111 nurse-tank versus stationary reference first.

This Norwesco tank ships LTL freight from the nearest of Norwesco's plants — Burnet, TX; Fairfield, TX; Griffin, GA; Hanford, CA; Lancaster, OH; Owego, NY; Shawnee, OK; Sheldon, IA; St.Bonifacius, MN; Tooele, UT, or Washougal, WA.That eleven-plant network means most U.S.ZIPs ship from a plant nearby rather than across the country, which keeps LTL reasonable on a tank this size.Because the loaded weight swings from about 542 lb on water to 813 lb at full 1.5 SG, and LTL is priced on weight and class, get your quote with your actual product density in mind — a denser load can move you into a higher freight tier.Get your freight quote in seconds with our Freight Cost Estimator, or call us at 866-418-1777 and we will route from the plant closest to you.
