The Enduraplas 3000 Gallon White Horizontal Leg Tank (SKU THF03000W) is a 3,000-gallon polyethylene horizontal leg tank built to carry heavy liquids on a wide, low footprint. It measures 90 inches tall by 87 inches wide by 130 inches long, giving an 87.0 x 130.0-inch footprint. The natural white wall lets you read the liquid level at a glance, and the molded leg design is made to seat into a cradle, pickup bed, or transport frame for field hauling. With a 1.9 specific gravity rating, this tank is engineered for liquids substantially heavier than water, which is what separates a true haul tank from a basic water tank.
Will it work for your job?
Capacity and weight are where this Enduraplas horizontal leg tank earns its place. Filled with water, the contents alone weigh about 25,020 lb. Loaded to the full 1.9 SG rating, the tank can carry up to roughly 47,538 lb of contents, so size your trailer, cradle, and tow vehicle to that maximum, not to the empty weight. The 1.9 SG figure is the top rating offered in this style, so there is no denser-rated step-up to fall back on if your fluid runs heavier. Run the numbers with the Tank Sizing Calculator and the Tank Sizing Guide before you commit a frame. Specific fitting sizes and outlet locations are not published in our data for this SKU, so confirm fitting placement against the technical drawing on this page and call 866-418-1777 before ordering. This tank shows up under searches for an Enduraplas horizontal leg tank, a 3000 gallon horizontal tank, and horizontal leg tanks generally because that is exactly what it is built to be: a transport-style vessel, not a stationary upright.
Chemical compatibility
This is a polyethylene tank with a 1.9 specific gravity rating. The resin is recorded as HDLPE, but the record is not fully confirmed, so verify HDLPE versus XLPE (crosslinked) with us before putting this tank into chemical service, because the two resins do not handle every chemical the same way. The chemicals below are drawn from the OEM chemical-resistance chart, which is concentration- and temperature-specific; always match your exact concentration and service temperature to the chart, and select the listed fitting and gasket materials. Note that the aggressive oxidizers on this list require the non-EPDM gaskets called out for them, so do not default to EPDM: Sodium Hypochlorite, Hydrogen Peroxide, and Phosphoric Acid call for Viton, and Peracetic Acid calls for Aflas.
Compatible chemicals and the fitting/gasket materials called out for each include: Acetic Acid at 60% (PP/PVC fittings, EPDM gaskets); Aluminum Sulfate at 50% (PVC, EPDM); Calcium Chloride at 40% (PVC, EPDM); DEF at 32.5% (316SS, EPDM); Ethylene Glycol at 100% (PVC, EPDM); Ferric Chloride at 50% (PVC, EPDM); Ferric Sulfate at 60% (PVC, EPDM); Ferrous Sulfate at 20% (PVC, EPDM); Hydrochloric Acid at 37% (PVC, Viton); Hydrofluoric Acid at 48% (PP/PVC, Viton); Hydrofluosilicic Acid at 26% (PP/PVC, Viton); Hydrogen Peroxide at 50% (PVC, Viton); Magnesium Chloride at 30% (PVC, EPDM); Peracetic Acid at 30% (316SS, Aflas); Phosphoric Acid at 85% (PVC, Viton); Polyaluminum Chloride (PVC, EPDM); Potassium Carbonate at 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 at 30% (PVC, EPDM); Sodium Hypochlorite below 16.5% (PVC, Viton); Sodium Thiosulfate at 40% (PVC, EPDM); Sulfuric Acid at 98% (CPVC, Viton); Urea Solution at 50% (PP/PVC, EPDM); Zinc Orthophosphate (PP/316SS, EPDM); and Ozonated Water up to 10 PPM (PVC, EPDM).

The mistake to avoid
The costliest error on a haul tank is matching the resin to the wrong service. A 1.9 SG rating tells you the tank can hold the weight of a dense liquid, but weight rating is not the same as chemical resistance. Confirm the resin (HDLPE versus XLPE) and pull the OEM chart for your exact concentration before you load anything more aggressive than water. For dense fertilizer blends, also account for stratification and salting-out; our guide on fertilizer-blend tank stratification walks through the mixing and field-verification steps that catch a stratified load before the spreader runs off-spec. If you are spec'ing this for a transport or applicator role, our notes on applicator and leg tanks for fertilizer and on loaf-style portable utility tanks and the 49 CFR 173.5 agricultural exemption explain how DOT classification applies to farm-fleet use.
