The Enduraplas 1900 Gallon Yellow Horizontal Leg Tank (SKU THF01900Y) is a polyethylene horizontal leg tank built for hauling and field transfer, rated to a 1.9 specific gravity so it can carry dense liquids and heavy ag chemistries without overstressing the wall. It measures 130 inches long by 71 inches wide by 65 inches tall, sits on integrated legs that keep it stable on a skid or trailer deck, and its bright yellow color makes it easy to spot in the yard. If you have been searching for a yellow Enduraplas horizontal leg tank in this class, this is the size that handles full agricultural transport loads.
Will it work for your load?
Capacity is 1900 gallons. Filled with plain water the contents weigh about 15,846 pounds, and at the tank's full 1.9 SG rating the maximum rated contents weight is roughly 30,107 pounds. That is about 14,261 pounds of headroom over water, and for any product you can estimate the load as 1,900 gallons multiplied by 8.34 multiplied by your specific gravity, so size your trailer, suspension, and axle ratings to the heaviest product you intend to haul, not just to water. The 71 x 130 inch footprint is what you need to confirm against your deck or cradle before you commit. For dimensioned views of the legs and overall geometry, see the technical drawing on this page. Fittings are configured to your application, so confirm port size and material by phone rather than assuming a standard layout. If you are weighing this against other capacities, the Tank Sizing Calculator and Tank Sizing Guide help you match gallons and weight to your equipment.
Chemical compatibility
This tank is molded from high-density linear polyethylene with a 1.9 specific gravity rating, the highest SG rating offered in this class, so no heavier-duty poly tank is needed for the chemistries listed below. The resin is recorded as HDLPE with a pending confirmation, so confirm whether your unit is HDLPE or XLPE before placing it into chemical service, since cross-linked and linear polyethylene differ in resistance to oxidizers and certain acids; call 866-418-1777 with your SKU to confirm resin before chemical service. Per the Enduraplas chemical-resistance chart, which is always concentration- and temperature-specific, the following are compatible at the listed concentrations when paired with the noted fitting and gasket materials: 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). Match fitting and gasket materials to your specific chemical, and review the full chemical compatibility reference before ordering.
The mistake to avoid
The number one error on a leg tank this size is loading to volume instead of to weight. A full 1900 gallons of a 1.9 SG product approaches 30,107 pounds of contents. The second is pairing the wrong gasket with an aggressive chemical: EPDM is fine for the salts and glycols above, but hydrochloric, hydrofluoric, hydrofluosilicic, hydrogen peroxide, phosphoric, sodium hypochlorite, and sulfuric acid all require Viton, and peracetic acid requires Aflas. The wrong elastomer fails long before the polyethylene does. Confirm the resin type, then confirm fittings and gaskets per the chart above.
