The Norwesco 150 Gallon Plastic Horizontal Leg Tank (SKU N-41468) is a white polyethylene horizontal leg tank built for haul-and-go service - mounted on a skid, trailer, or pickup bed for moving water, fertilizer, and field chemicals. It measures 36 in high by 34 in wide by 43 in long, with molded support legs that let the tank sit stable on a flat deck without a separate cradle. Rated to 1.5 specific gravity, it carries denser-than-water solutions up to that weight ceiling, not just plain water. This is the horizontal leg-tank format farmers and applicators search for as a 150 gallon nurse or applicator tank.
Will this tank work for your load
At 150 gallons of plain water the tank weighs about 1,251 lb full, and the 1.5 specific-gravity rating allows a maximum rated contents weight near 1,876 lb. Size your mount, hauler, and tie-downs to the heavier 1,876 lb figure if you are filling with fertilizer or a chemical solution, not the water number. The 34 x 43 in footprint is what you need to plan deck space and strapping. Because freight on a loaded tank this heavy is a real cost driver, it ships LTL from the Norwesco plant in Burnet, TX - get your ZIP freight before you buy with our Freight Cost Estimator. If you are unsure whether 150 gallons matches your job, run the numbers with our Tank Sizing Calculator and review the Tank Sizing Guide first. The horizontal leg design is what makes this format work as a portable applicator or nurse tank rather than a stationary vertical.
Chemical compatibility
This is a polyethylene tank rated to 1.5 specific gravity. Confirm the resin type of your specific tank - HDLPE versus XLPE - before putting it into chemical service, since resin type affects what you can safely store. This SKU ships without factory fittings, so plan to match your fitting and gasket materials to the chemical you are running. Against the OEM chemical-resistance chart - which is concentration- and temperature-specific - the 1.5 SG rating supports these solutions: Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF at 32.5% (316SS fittings, EPDM gaskets), Ferrous Sulfate (20%, PVC, EPDM), Magnesium Chloride (30%, PVC, EPDM), Sodium Carbonate (30%, PVC, EPDM), Urea Solution (50%, PP/PVC, EPDM), and Ozonated Water up to 10 PPM (PVC, EPDM). Note that DEF is the outlier on hardware - it calls for 316SS fittings rather than the PVC most of the others use - so a 150 gallon DEF transport build needs stainless fittings and an EPDM gasket, not the PVC plumbing you would run for the sulfates. Verify the exact concentration and temperature against the chart, and review our full chemical compatibility reference for your application.
The mistake to avoid: don't under-rate the specific gravity
The most common error with this tank is treating its 1.5 SG ceiling as the limit for everything. Several common solutions need a higher 1.9 specific-gravity tank, not this one - 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. Several of those also move to Viton or Aflas gaskets rather than EPDM. If your chemical is on that list, this 1.5 SG tank is the wrong tank - you need a 1.9 SG model instead.
