The Enduraplas 2500 Gallon Yellow Horizontal Sump Bottom Leg Tank with frame is built for hauling heavy agricultural and industrial liquids over the road and across the field. Molded in yellow polyethylene at a 1.9 specific gravity rating, this horizontal leg tank measures 87 inches wide by 130 inches long and stands 78 inches tall, with a sump bottom and integrated frame that cradle and support the body when loaded. The 1.9 SG rating is the number that tells you what this tank can legitimately haul: it is rated for contents up to that density, not just water.
Will it work for your load?
At 2500 gallons, water alone weighs about 20,850 lb full. Because the tank is rated to 1.9 specific gravity, it is engineered for liquids substantially heavier than water, up to roughly 39,615 lb of rated contents at maximum density. That headroom is what makes a 1.9-rated horizontal leg tank the right pick for dense fertilizer blends, DEF, and heavy chemical loads where a standard 1.0 to 1.5 SG tank would be over its limit. Before you commit, check the hard numbers: footprint 87 in W x 130 in L, 78 in tall. Verify deck width and any overhead or door clearance against those dimensions, and confirm your trailer and axle ratings against the full loaded weight. The sump bottom matters most with settling-prone loads like ferric sulfate, aluminum sulfate, and polyaluminum chloride, where it lets you draw down to a clean drain instead of leaving a sediment heel.
Fittings: confirm on the drawing
Outlet size and fitting placement are not published in this listing. Review the technical drawing on this page for the actual port layout on this unit, and confirm size and location with us at 866-418-1777 before you order chemical-service fittings. Do not assume a fitting set is included or that a given port size is present until it is verified.
Chemical compatibility
This tank is polyethylene rated at 1.9 specific gravity. The resin is reported as HDLPE, but confirm HDLPE versus XLPE before placing it into chemical service, because the two crosslink differently and that affects long-term resistance. Compatibility below is drawn from the OEM chemical-resistance chart and is concentration- and temperature-specific. Always verify your exact concentration and service temperature against that chart before committing.
At the listed concentrations, this tank pairs with the following chemicals and recommended fitting and gasket materials: Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), 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 (under 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). Match the fitting and gasket material to your chemical, and see our full chemical compatibility reference for the complete picture.
The mistake to avoid
The most common error on a tank like this is choosing fittings and gaskets by habit instead of by chemical. Look at the list above: DEF and Peracetic Acid both call for 316 stainless fittings, several acids need Viton rather than EPDM gaskets, and Sulfuric Acid at 98% wants CPVC. Putting EPDM on a Viton-required service, or PVC where stainless is specified, is how a chemically compatible tank still ends up with a leaking or failed connection. Confirm your concentration and temperature against the OEM chart, and verify the resin (HDLPE versus XLPE) before you fill it.
