The Enduraplas 1010 Gallon Green Horizontal Sump Bottom Leg Tank is a 130-inch-long horizontal vessel built for transport and applicator duty, where the load has to ride low and stay put. It holds 1,010 gallons in a 49 x 130 inch footprint, stands 59 inches tall, and is molded in green polyethylene with a sump bottom so the tank drains clean to its low point. The integrated frame is what makes this a haul tank rather than a stationary one: it carries the tank as a unit on a trailer or skid for field-applicator and horizontal-tank service. If you searched for an Enduraplas horizontal leg tank or a horizontal sump tank for fertilizer or liquid hauling, this is the size class you landed on.
Will it work for your load?
This tank carries a 1.9 specific-gravity rating, a heavy-duty wall rating well above plain water. Full of water at 1,010 gallons it holds about 8,423 pounds of contents; loaded to its maximum rated content weight it handles up to 16,004 pounds, so you have real headroom for dense fertilizer blends and the chemicals listed below. Key specs to check against your rig:
- Capacity: 1,010 gallons
- Footprint: 49 x 130 inches; height 59 inches
- Full-water weight: ~8,423 lb contents
- Maximum rated content weight: 16,004 lb
- Specific gravity rating: 1.9
- Ships from: Converse, TX
Use the Tank Sizing Calculator and the Tank Sizing Guide to match the gallons-and-weight math to your trailer rating and axle capacity before you load. Confirm your frame, hitch, and tow vehicle are rated for a filled weight near the 16,004-pound ceiling, not just the empty tank. Fitting and outlet configuration is not specified in our data for this tank, so call 866-418-1777 to confirm the sump outlet size and the fill and vent locations before you order.
Chemical compatibility
This is a polyethylene tank with a 1.9 specific-gravity rating. Confirm whether the actual construction is linear (HDLPE) or cross-linked (XLPE) with us at 866-418-1777 before committing it to chemical service, since cross-link versus linear behavior matters for aggressive fluids. At its 1.9 SG rating this tank supports a broad chemical list, with each chemical requiring its own fitting and gasket materials. Always size fittings and gaskets to the chemical, and verify against the OEM chemical-resistance chart at your exact concentration and temperature.
Compatible chemicals from our data include 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; reference data point, no dedicated page). See the chemical compatibility hub for the full picture.
The mistake that bites this size of tank most is matching the gasket to the chemical wrong. Several fluids above will not tolerate EPDM: specify Viton gaskets for Hydrochloric Acid (37%), Hydrofluoric Acid (48%), Hydrofluosilicic Acid (26%), Hydrogen Peroxide (50%), Phosphoric Acid (85%), Sodium Hypochlorite (under 16.5%), and Sulfuric Acid (98%); specify Aflas for Peracetic Acid (30%); and plan on 316SS fittings for DEF, Peracetic Acid, Propylene Glycol, and Zinc Orthophosphate.
The mistake to avoid
The most common error on a horizontal leg tank this large is treating the SG rating as if it sets your trailer limit. The 1.9 rating describes the tank wall; your contained weight can still reach 16,004 pounds, and that filled load is what your frame, trailer, and tow rating must carry. For agricultural and applicator use, review our guides on applicator and leg tanks for fertilizer, portable utility tanks and 49 CFR DOT classification, and fertilizer-blend tank stratification to set up your fill and mixing protocol correctly. For exact fitting positions and dimensions, see the technical drawing on this page.
