The Enduraplas 1000 Gallon Green Horizontal Sump Bottom Leg Tank is a polyethylene horizontal leg tank rated for a 1.9 specific gravity, built to haul heavier-than-water liquids over the road on a trailer or skid. It measures 94 inches long by 60 inches wide by 70 inches high, with integrated legs and a sump bottom that let you mount it, transport it, and drain it down without leaving product stranded in the belly. At 1000 gallons, this is a workhorse for applicators, fertilizer haulers, and anyone moving dense chemistry between a fill point and the field.
Will it handle your load?
The 1.9 specific gravity rating is the number that matters here. Full of water this tank carries roughly 8,340 pounds, but at 1.9 SG the contents alone can reach up to 15,846 pounds - close to 1.9 times the water weight. That dense-fill case, not water, is what your axle rating, frame, and tie-downs must be sized to. Run the loaded numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you spec a trailer or skid, so the chassis is matched to a fully loaded tank rather than an empty shell. The 60 x 94 inch footprint tells you exactly how much deck this consumes. See the technical drawing on this page for fitting locations and the sump detail.
Chemical compatibility
Confirm the resin first. This tank is polyethylene at a 1.9 SG rating, and the resin is recorded as HDLPE but flagged for confirmation - so confirm HDLPE versus XLPE with us before committing it to chemical service. The distinction changes long-term behavior dramatically, especially with the strong acids below, so treat it as a prerequisite, not a footnote. All values come from the OEM chemical-resistance chart, which is always concentration- and temperature-specific.
At the listed concentrations and fitting/gasket materials, this tank pairs 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 (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).
Watch list - the chemistries that demand non-default hardware: Viton gaskets for Sodium Hypochlorite, Hydrochloric, Hydrofluoric, Hydrofluosilicic, Hydrogen Peroxide, Phosphoric, and Sulfuric Acid; 316SS fittings for DEF and Peracetic Acid; and Aflas gaskets specifically for Peracetic Acid at 30%. Matching the fitting and gasket material to your chemical is the mistake that sinks a tank install - and the sump bottom matters here too: it lets you fully drain and flush dense product between loads so residue and cross-contamination don't carry over. The chart values are concentration- and temperature-specific, so verify yours against the OEM chart and our chemical compatibility reference before ordering.
Freight and ordering
This tank ships LTL freight from the Enduraplas plant in Neche, ND, quoted live to your ZIP code. A 1000 gallon horizontal leg tank is a large, heavy unit, so freight is calculated per destination rather than baked into the list price - get your number from the Freight Cost Estimator or call us at 866-418-1777. If you are hauling fertilizer or building a road-going applicator setup, the applicator and leg tank guide, the portable utility tank DOT classification breakdown, and the fertilizer-blend stratification guide walk through the regulatory and mixing details that protect both your load and your spreader calibration.
