The Enduraplas 2500 Gallon White Horizontal Leg Tank is a haul-and-store workhorse for moving water and dense ag chemistries to the field. It holds 2,500 gallons, measures 130 inches long by 87 inches wide by 75 inches tall, and rides on integrated legs sized to sit flat on a trailer or skid. Molded in natural white polyethylene with a 1.9 specific gravity rating, this horizontal leg tank is built to carry heavy loads, not just water - which is exactly why that SG number matters before you fill it.
Will it work for your load?
Run the math before you buy. Filled with water, this tank carries roughly 20,850 lbs of contents, and its 1.9 SG rating allows a maximum rated contents weight of about 39,615 lbs for denser fluids. That headroom is what makes it a true horizontal tank for fertilizer blends and heavy solutions rather than a water-only vessel. Confirm your trailer, axles, and tie-downs are rated for the full loaded weight, and use the Tank Sizing Calculator and Tank Sizing Guide to match gallons and weight to your hauling setup. The 87 x 130 inch footprint is the number to check against your deck width and length first. Fittings on a leg tank this size are configured to the job, so confirm port count, size, and placement with us at 866-418-1777 before you plumb it.
Chemical compatibility
This is a 1.9 SG polyethylene tank. The resin is recorded as HDLPE but unconfirmed - call 866-418-1777 to verify HDLPE versus XLPE before any chemical service, since the resin (not just the SG) governs what it can safely hold. The compatibility below comes from the OEM chemical-resistance chart and is concentration- and temperature-specific, so verify your exact concentration and operating temperature before committing. At 1.9 SG this is already the heavy-duty rating for this size class - for the dense fertilizer and acid blends listed here, you do not need to step up to a denser tank.
At the listed concentrations, this tank is rated for fluids including Acetic Acid (60%), Aluminum Sulfate (50%), Calcium Chloride (40%), DEF (32.5%), Ethylene Glycol (100%), Ferric Chloride (50%), Ferric Sulfate (60%), Ferrous Sulfate (20%), Hydrochloric Acid (37%), Hydrofluoric Acid (48%), Hydrofluosilicic Acid (26%), Hydrogen Peroxide (50%), Magnesium Chloride (30%), Peracetic Acid (30%), Phosphoric Acid (85%), Polyaluminum Chloride, Potassium Carbonate (50%), Potassium Hydroxide (saturated), Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Carbonate (30%), Sodium Hypochlorite (<16.5%), Sodium Thiosulfate (40%), Sulfuric Acid (98%), Urea Solution (50%), Zinc Orthophosphate, and Ozonated Water (up to 10 PPM). Match fittings and gaskets to the chart for your specific chemical: the default is PVC fittings with EPDM gaskets, but oxidizers and strong acids step up to Viton - Hydrochloric, Hydrofluoric, Hydrofluosilicic, Hydrogen Peroxide, Phosphoric, Sodium Hypochlorite, and Sulfuric all call for it (Sulfuric on CPVC) - and Peracetic Acid requires Aflas gaskets with 316SS fittings. Hauling DEF? It is rated at 32.5%, but DEF requires 316SS fittings, not PVC, with EPDM gaskets, so budget for stainless before you plumb. Start from our full chemical compatibility reference.
Don't make this mistake
The most common error on a 1.9 SG horizontal leg tank is treating it like a water tank. The 1.9 rating exists so the polyethylene wall can handle dense fluids - but contents weight, not gallon count, is what stresses your trailer and tie-downs. A full load of heavy chemistry can approach 39,615 lbs, so size your transport to the rated contents weight, not the water weight. Pair the right fittings and gaskets to your chemical from the start, and see the technical drawing on this page for the leg layout before you set it on a deck. If you are running fertilizer blends, our guide on fertilizer-blend tank stratification and on applicator and leg tanks for fertilizer covers field handling and DOT scope.
