The Enduraplas 2800 Gallon Black Horizontal Leg Tank is a portable haul-and-transfer tank built for moving large volumes of liquid across a farm, applicator route, or job site. Molded in black polyethylene with a 2,800-gallon capacity and a 1.9 specific gravity rating, this is one of the heavier-duty horizontal leg tanks you can run - the leg-supported, low-slung profile keeps the center of gravity down for towing and transfer work. Overall dimensions are 145 inches long by 97 inches wide by 75 inches high, giving it a 97.0 x 145.0 inch footprint you should confirm against your trailer deck or skid before ordering.
Will it work for your job?
Plan your load by weight, not just gallons. Filled with water this tank carries 23,352 lb of contents; at its full 1.9 SG rating it is engineered for up to 44,369 lb of contents weight - and 1.9 is the maximum rating in this line, so there is no heavier-duty step-up above it. That spread matters: a denser product such as a fertilizer blend or brine puts dramatically more load on the tank wall, your trailer, and your tow vehicle than plain water does. Size the supporting trailer, axles, and tie-downs to the heaviest product you will actually haul - run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you commit. For how leg and applicator tanks are classified for road use, the guide on applicator and leg tanks for fertilizer and the writeup on portable utility tanks and the 49 CFR 173.5 agricultural exemption are worth reading before you put a loaded horizontal tank on the highway.
Chemical and fluid compatibility
This tank is molded in HDLPE at a 1.9 specific gravity rating. The resin is listed as HDLPE with a trailing question mark in our source data, so confirm HDLPE versus XLPE construction before chemical service - and treat that confirmation as a hard precondition for the aggressive acids below, where the HDLPE/XLPE distinction materially changes suitability. With the right fitting and gasket materials, this tank is rated to handle a broad slate per the OEM chemical-resistance chart, which is always concentration- and temperature-specific. One high-demand fit for a tank of this size and ND origin: it handles DEF at 32.5% with 316 stainless fittings and EPDM gaskets, and Urea Solution at 50% with PP/PVC fittings and EPDM. Before you default to PVC and EPDM, watch the outliers - Sulfuric Acid 98% needs CPVC fittings with Viton gaskets, DEF and Peracetic Acid need 316 stainless, the strong acids (HCl, HF, hydrogen peroxide, phosphoric, hypochlorite, sulfuric) need Viton gaskets, and Peracetic Acid needs Aflas. The full rated slate:
Acetic Acid 60% (details, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate 50% (details, PVC, EPDM), Calcium Chloride 40% (details, PVC, EPDM), DEF 32.5% (details, 316SS, EPDM), Ethylene Glycol 100% (details, PVC, EPDM), Ferric Chloride 50% (details, PVC, EPDM), Ferric Sulfate 60% (details, PVC, EPDM), Ferrous Sulfate 20% (details, PVC, EPDM), Hydrochloric Acid 37% (details, PVC, Viton), Hydrofluoric Acid 48% (details, PP/PVC, Viton), Hydrofluosilicic Acid 26% (details, PP/PVC, Viton), Hydrogen Peroxide 50% (details, PVC, Viton), Magnesium Chloride 30% (details, PVC, EPDM), Peracetic Acid 30% (details, 316SS, Aflas), Phosphoric Acid 85% (details, PVC, Viton), Polyaluminum Chloride (details, PVC, EPDM), Potassium Carbonate 50% (details, PVC, EPDM), Potassium Hydroxide saturated (details, PVC, EPDM), Propylene Glycol (details, PP/316SS, EPDM), Sodium Bisulfate (details, PVC/PP, EPDM), Sodium Bisulfite (details, PVC/PP, EPDM), Sodium Carbonate 30% (details, PVC, EPDM), Sodium Hypochlorite under 16.5% (details, PVC, Viton), Sodium Thiosulfate 40% (details, PVC, EPDM), Sulfuric Acid 98% (details, CPVC, Viton), Urea Solution 50% (details, PP/PVC, EPDM), Zinc Orthophosphate (details, PP/316SS, EPDM), and Ozonated Water up to 10 PPM (PVC, EPDM). Match every fitting and gasket to the product you are running, and verify your exact concentration and temperature against the OEM chart. See our full chemical compatibility resource to cross-check before service.
The mistake to avoid
The trap on a tank this size is misreading the 1.9 SG rating. It does not mean the tank weighs less when full - it means the wall is built to carry up to 44,369 lb of dense contents. Plenty of buyers spec the tank correctly but undersize the trailer or tow rig for water weight (23,352 lb) and get caught when they load a heavy fertilizer blend. The second trap is fittings: we do not have factory fitting or outlet specs listed for this SKU, so check the technical drawing on this page and call 866-418-1777 to confirm port count, size, and location before you order and plumb. If you are blending product in this tank, stratification is a real field problem; the guide on fertilizer-blend tank stratification covers the mixing protocol that keeps a load on-spec.
