The Enduraplas 1600 Gallon White Horizontal Leg Tank (SKU THF01600W) is a 1,600-gallon natural white polyethylene horizontal leg tank built for hauling and field transport. It carries a 1.9 specific gravity rating - the high-density end of the scale - which is what lets it move dense agricultural and industrial liquids rather than just water. The tank measures 130 inches long, 71 inches wide, and 59 inches high, sitting on integrated legs that cradle the horizontal body so it rides flat on a trailer or skid. If you have been searching for an Enduraplas horizontal leg tank in white, this is the large-capacity end of that line.
Will it work for your load?
Filled with water, this tank weighs about 13,344 pounds, and at its 1.9 SG rating it is engineered to carry contents up to roughly 25,354 pounds. Use the higher number as your true planning figure if you are hauling fertilizer, brine, or other heavy liquids, then size your trailer axles and tongue weight against it before the first run. That 1.9 SG is already the top-tier density rating on this tank, so for heavy chemistry there is no step-up version needed - this is the heavy-duty spec. The footprint is 71.0 x 130.0 inches, so confirm your deck length and width and your tie-down points line up with the leg pattern. At 59 inches tall, a fully loaded horizontal body of this size carries a high center of gravity, so check bridge and door clearance and your trailer rail height before you haul. The geometry, leg spacing, and overall dimensions are shown on the technical drawing on this page. For matching capacity to your job and confirming weight per gallon at your liquid's density, run the numbers through our Tank Sizing Calculator and review the Tank Sizing Guide.
Chemical compatibility
This tank is rated to a 1.9 specific gravity. The exact polyethylene resin grade is not confirmed in our data, so confirm the resin with us before putting it into chemical service - different polyethylene grades behave differently against certain reagents. Compatibility below is drawn from the OEM chemical-resistance chart and is concentration- and temperature-specific; verify your exact conditions before committing. As a quick spec map: EPDM gaskets cover most salts, bases, and glycols; Viton is called for on the strong acids and on sodium hypochlorite; Aflas is specific to peracetic acid. Watch the fitting metal too - DEF and peracetic acid call for 316SS, and sulfuric acid calls for CPVC. Specify fittings and gaskets in the materials called out for each chemical:
- Acetic Acid 60% - PP/PVC fittings, EPDM gasket
- Aluminum Sulfate 50% - PVC fittings, EPDM gasket
- Calcium Chloride 40% - PVC fittings, EPDM gasket
- DEF 32.5% - 316SS fittings, EPDM gasket
- Ethylene Glycol 100% - PVC fittings, EPDM gasket
- Ferric Chloride 50% - PVC fittings, EPDM gasket
- Ferric Sulfate 60% - PVC fittings, EPDM gasket
- Ferrous Sulfate 20% - PVC fittings, EPDM gasket
- Hydrochloric Acid 37% - PVC fittings, Viton gasket
- Hydrofluoric Acid 48% - PP/PVC fittings, Viton gasket
- Hydrofluosilicic Acid 26% - PP/PVC fittings, Viton gasket
- Hydrogen Peroxide 50% - PVC fittings, Viton gasket
- Magnesium Chloride 30% - PVC fittings, EPDM gasket
- Peracetic Acid 30% - 316SS fittings, Aflas gasket
- Phosphoric Acid 85% - PVC fittings, Viton gasket
- Polyaluminum Chloride - PVC fittings, EPDM gasket
- Potassium Carbonate 50% - PVC fittings, EPDM gasket
- Potassium Hydroxide saturated - PVC fittings, EPDM gasket
- Propylene Glycol - PP/316SS fittings, EPDM gasket
- Sodium Bisulfate - PVC/PP fittings, EPDM gasket
- Sodium Bisulfite - PVC/PP fittings, EPDM gasket
- Sodium Carbonate 30% - PVC fittings, EPDM gasket
- Sodium Hypochlorite <16.5% - PVC fittings, Viton gasket
- Sodium Thiosulfate 40% - PVC fittings, EPDM gasket
- Sulfuric Acid 98% - CPVC fittings, Viton gasket
- Urea Solution 50% - PP/PVC fittings, EPDM gasket
- Zinc Orthophosphate - PP/316SS fittings, EPDM gasket
- Ozonated Water up to 10 PPM - PVC fittings, EPDM gasket (no reference page yet; call us at 866-418-1777 for guidance)
Full details for many of these are on our chemical compatibility reference. The most common mistake on a tank like this is reusing one set of fittings across chemistries; match the fitting and gasket material to the specific reagent every time.
Freight and ordering
This tank ships LTL by freight, quoted live to your ZIP, from the Enduraplas plant in Neche, North Dakota. The 13,344 and 25,354 pound figures are contents weight, not shipping weight - the empty tank ships as a single large piece and its empty weight is not listed here, so confirm it through the Freight Estimator or by phone before you finalize logistics. Get an accurate door-to-door number with our Freight Cost Estimator before you order. If you are spec'ing this into an applicator or fertilizer hauling setup, our guides on applicator and leg tanks for fertilizer and fertilizer-blend tank stratification are worth a read.
