The Enduraplas 1010 Gallon Yellow Horizontal Sump Bottom Leg Tank is a Converse, Texas-built horizontal leg tank rated for a 1.9 specific gravity, which is the spec that lets it haul dense agricultural and industrial liquids that would overload a standard water tank. Molded in yellow polyethylene with a sump bottom and an integrated frame, it measures 130 inches long, 49 inches wide, and 59 inches tall, giving it a 49.0 x 130.0 footprint that drops onto a trailer or skid for field and transport use. The sump-bottom geometry pulls contents toward the low point so the tank drains cleaner than a flat-bottom horizontal of the same capacity.
Will it handle your load
Full of water this tank carries about 8,423 pounds, and at its 1.9 SG rating it is built to hold up to 16,004 pounds of contents. That leaves roughly 7,581 pounds of structural headroom above a full water load, which is the number that matters before you fill it: water and most fertilizer blends sit well under the ceiling, but heavy mineral solutions and acids climb fast. In practical terms, 16,004 pounds across 1,010 gallons works out to a ceiling near 15.8 pounds per gallon, so check any product's density spec sheet against that figure and do not exceed it. Size the trailer, frame support, and tie-downs to the actual product weight, not to the water figure. Confirm your loaded weight against the Tank Sizing Calculator and the Tank Sizing Guide, and check the technical drawing on this page for outlet and fitting locations before you plumb it.
Chemical compatibility
Before reading the list below as a guarantee, settle the resin question first. This is a polyethylene tank with a 1.9 specific gravity rating, and the resin is recorded as HDLPE but is not fully confirmed, so confirm HDLPE versus XLPE with us at 866-418-1777 before putting it into dedicated chemical service. Compatibility always depends on resin, concentration, and temperature, so check the OEM chemical-resistance chart for the concentration and temperature you actually run before committing. Most of the chemicals below run on PVC fittings with EPDM gaskets, but watch the exceptions that need upgraded hardware: DEF and peracetic acid call for 316SS, peracetic also needs Aflas gaskets, sulfuric acid at 98% needs CPVC, and hydrochloric, hydrofluoric, hydrofluosilicic, hydrogen peroxide, phosphoric, and sodium hypochlorite all need Viton gaskets. Plan that costlier plumbing in before you commit.
At the 1.9 SG rating, this tank is referenced for service with 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). Match the fitting and gasket material to the chemical, and see the full chemical compatibility reference to plan your plumbing.
The mistake to avoid
The trap on a tank like this is treating the 1.9 SG rating as a license to fill it with any dense liquid. The rating governs structural load, not chemical attack: a product that fits under the 16,004-pound ceiling can still degrade the wrong fitting or gasket. Spec PVC, CPVC, PP, or 316SS hardware and EPDM, Viton, or Aflas gaskets to the specific chemical and concentration, and confirm the resin before dedicated service. Whether you are hauling fertilizer blends or running it as a stationary sump tank, the weight and material checks come first.
