The Enduraplas 1900 Gallon Black Horizontal Leg Tank is a hauling and storage tank built for moving heavy liquids across the farm, the lot, or the chemical-handling yard. Molded in black polyethylene at a 1900-gallon capacity, it carries a 1.9 specific gravity rating, which is what lets it legitimately haul liquids far denser than water. The footprint is 71 inches wide by 130 inches long, standing 65 inches tall on integrated support legs that keep the tank cradled and stable for transfer. If you are sizing a nurse tank, a tender, or a stationary fill station, this is the kind of horizontal leg tank that handles real working loads.
Will it handle your load?
Filled with water this tank holds roughly 15,846 pounds. The 1.9 SG rating means it is engineered to carry up to about 30,107 pounds of contents at maximum density, so you have real headroom for heavy fertilizer blends, brines, and dense chemical solutions rather than water alone. That 1.9 figure is the top density rating in this line, so there is no heavier-duty step-up to chase: this is already the maximum-density horizontal leg tank you can spec here. Use the technical drawing on this page to confirm leg spacing, outlet location, and overall geometry against your skid, trailer, or pad before you commit. If you are still narrowing capacity, the Tank Sizing Calculator and Tank Sizing Guide walk you through matching volume and weight to your application. One caution on a leg tank built for transport: the legs let you mount it on a skid or trailer frame, but the tank itself is not a DOT highway-transport rating. On-road hauling of regulated chemicals is governed by DOT, and our guide on applicator and leg tanks for fertilizer covers non-roadable trailer scope, while the portable utility tank classification guide explains the 49 CFR 173.5 agricultural exemption for farm fleet use.
Chemical compatibility
This tank is molded polyethylene carrying a 1.9 specific gravity rating, recorded as HDLPE. Because crosslinked and linear polyethylene behave differently with aggressive chemistries, confirm HDLPE versus XLPE with us before committing to any chemical service. Note also that the tank ships without chemical-service fittings pre-installed: the bulkhead, outlet, and gasket hardware is matched per chemical at order, which is exactly why the materials below matter. Compatibility is drawn from the OEM chemical-resistance chart and is concentration- and temperature-specific, so verify your exact concentration and operating temperature against that chart before ordering.
Within the 1.9 SG rating, this tank is listed compatible with: 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 ozonated-water rating comes from the resistance chart only, with no dedicated resource page yet. Match the fitting and gasket material to your chemical exactly, and see our full chemical compatibility resource to plan the build.
The mistake to avoid
The big one on a dense-liquid hauler is the gasket. Notice that the chlorine and strong-acid services above call for Viton rather than EPDM, and DEF and peracetic acid call for 316SS or Aflas. Putting an EPDM gasket on a Viton-rated chemical, or running PVC where 316SS is specified, is the failure most people make on a tank this capable. Decide your fluid first, then confirm the resin (HDLPE versus XLPE) and the fitting and gasket materials against the chemical-resistance chart. For dense fertilizer blends, our write-up on fertilizer-blend tank stratification covers the mixing and field-verification steps that catch a stratified tank before the spreader runs off-spec.
