The Enduraplas 1600 Gallon White Horizontal Sump Bottom Leg Tank is a 130-inch-long polyethylene haul tank built for moving dense liquid down the road and across the field. It stands 60 inches tall, 71 inches wide, and 130 inches long on its integrated legs and frame, carrying 1,600 gallons at a 1.9 specific gravity rating, so it is engineered to haul heavy agricultural and industrial liquids that would overstress a lighter-rated tank. The sump bottom drains the load completely, and the leg-and-frame design seats the tank in a trailer or skid without a separate cradle. If you are shopping enduraplas horizontal tank, leg tank, or sump-bottom hauling options, this is the heavy-duty end of that range.
Will it work for your load?
Start with weight, because on a horizontal leg tank that is what governs your trailer and your axle rating. Filled with water this tank weighs about 13,344 lb. At its full 1.9 specific gravity rating it can carry up to roughly 25,354 lb of contents, which is the real number to plan around if you are hauling fertilizer blends, brine, or other heavy liquids. The 71 x 130 inch footprint tells you the deck space you need; confirm it against your trailer before you order, and run your fill against the Tank Sizing Calculator and Tank Sizing Guide so you size the chassis to the loaded weight, not the empty tank. Fitting and outlet sizes are not yet published for this SKU; they are confirmed per order, so call 866-418-1777 with your plumbing needs, and see the technical drawing on this page for dimension callouts.
Chemical compatibility
This is a polyethylene tank with a 1.9 specific gravity rating. The resin is recorded as HDLPE pending OEM confirmation, so before any chemical service confirm whether your tank is HDLPE or XLPE with us at 866-418-1777 — that single fact decides what it can safely hold. Per the OEM chemical-resistance chart, which is concentration- and temperature-specific, this tank is rated for the chemicals below. Match the fitting and gasket material to your chemical, because the seal is what fails first if you get it wrong.
| Chemical | Concentration | Fitting | Gasket |
|---|---|---|---|
| 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 | not specified — confirm | PVC | EPDM |
| Potassium Carbonate | 50% | PVC | EPDM |
| Potassium Hydroxide | Saturated | PVC | EPDM |
| Propylene Glycol | not specified — confirm | PP/316SS | EPDM |
| Sodium Bisulfate | not specified — confirm | PVC/PP | EPDM |
| Sodium Bisulfite | not specified — confirm | 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 | not specified — confirm | PP/316SS | EPDM |
| Ozonated Water | up to 10 PPM | PVC | EPDM |
Always check your specific chemical, concentration, and service temperature against our full chemical compatibility reference before committing a load.
The mistake to avoid
The error that ruins a tank like this is reading the 1.9 rating as a license to fill it with anything heavy and forget the gasket. The 1.9 specific gravity rating means the shell can structurally carry dense liquid, but the seal materials are what actually contain it: the chart calls for Viton on the strong acids and hypochlorite and EPDM on the salts and glycols, and the wrong gasket fails first. Pair that with the resin question above — lock down HDLPE versus XLPE before the first chemical fill. For dense ag and fertilizer service, the fertilizer-blend stratification guide and our applicator and leg tank and portable utility tank DOT scope writeups are worth reading before you haul.
