The Enduraplas 3200 Gallon Green Horizontal Sump Bottom Leg Tank ships with its integrated frame and a sump-bottom design built for transport and applicator duty. At 145 inches long, 97 inches wide, and 84 inches tall, this horizontal leg tank carries 3,200 gallons over a 97.0 x 145.0-inch footprint. The polyethylene shell is rated to a 1.9 specific gravity, which is what makes it a chemical and fertilizer hauler rather than a water-only tank.
Will it work for your load? Start with the weights, not the gallons
The two numbers that govern this purchase are not the 3,200 gallons. Filled with plain water, contents weigh about 26,688 lb. Loaded with the densest product the 1.9 SG shell is rated for, contents can reach roughly 50,707 lb. Your trailer, frame, and axle ratings must support the heavier figure, not the gallon count, because the SG rating tells you what density the shell can carry, not what your running gear can haul. That makes this tank a natural fit for high-volume horizontal haul services like DEF and ethylene or propylene glycol, with the fitting caveats noted below. The sump bottom drains cleanly between batches and the molded leg and frame geometry keeps the body stable in transit. Run your figures through the Tank Sizing Calculator or read the Tank Sizing Guide when matching this 3,200-gallon Enduraplas horizontal to a carrier.
Two specs to confirm before you order
The resin is recorded as polyethylene, but HDLPE versus XLPE is not confirmed in this listing (shown as "HDLPE?"). Confirm that construction before committing the tank to any chemical service, since it changes what the shell will hold. This listing also does not specify factory fitting sizes or locations, so confirm port count, thread size, and sump outlet with us at 866-418-1777 before ordering. Review the technical drawing on this page alongside that conversation.
Chemical compatibility
This is a polyethylene tank rated to 1.9 specific gravity. Because the resin is recorded as HDLPE with a trailing question mark, confirm HDLPE versus XLPE before chemical service. Every pairing below comes from the OEM chemical-resistance chart and is concentration- and temperature-specific, so verify your exact product and operating temperature against it. Match the fitting and gasket material to what you are hauling: Acetic Acid (60%, PP/PVC, EPDM), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS, EPDM), Ethylene Glycol (100%, PVC, EPDM), Ferric Chloride (50%, PVC, EPDM), Ferric Sulfate (60%, PVC, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Hydrochloric Acid (37%, PVC, Viton), Hydrofluoric Acid (48%, PP/PVC, Viton), Hydrofluosilicic Acid (26%, PP/PVC, Viton), Hydrogen Peroxide (50%, PVC, Viton), Magnesium Chloride (30%, PVC, EPDM), Peracetic Acid (30%, 316SS, Aflas), Phosphoric Acid (85%, PVC, Viton), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate (50%, PVC, EPDM), Potassium Hydroxide (saturated, PVC, EPDM), Propylene Glycol (PP/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), Sodium Carbonate (30%, PVC, EPDM), Sodium Hypochlorite (<16.5%, PVC, Viton), Sodium Thiosulfate (40%, PVC, EPDM), Sulfuric Acid (98%, CPVC, Viton), Urea Solution (50%, PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). Start from the full chemical compatibility reference.
The mistake to avoid
The common error on a tank like this is treating the 1.9 specific gravity rating as a free pass. It is not. The rating tells you the maximum product density the shell can carry; it does not change the weights your running gear must support, and it does not let you reuse one fitting and gasket spec across every product. DEF needs 316 stainless fittings rather than PVC; sodium hypochlorite and the strong acids call for Viton gaskets instead of EPDM. Putting an EPDM gasket on 98% sulfuric, or a PVC fitting on DEF, is how a sump-bottom hauler develops a field leak. Confirm the resin first, then match every fitting and gasket to the exact product before filling.
