The Enduraplas 2800 Gallon Yellow Horizontal Leg Tank (SKU THF02800Y) is a polyethylene horizontal leg tank built to haul heavy liquids and concentrated farm and water-treatment chemistry over the road and across the field. It carries a 1.9 specific gravity rating, the top of the leg-tank density range, which is what lets it legally transport products far heavier than water. The tank measures 75 inches high, 97 inches wide, and 145 inches long, with a 97.0 x 145.0 inch footprint, so it rides low and wide on a trailer or applicator frame for stable transport. If you have been searching for a yellow Enduraplas horizontal leg tank for a haul rig or applicator setup, this is the size that bridges nurse-tank capacity and over-the-road manageability.
Will it work for your job?
Filled with plain water the contents weigh about 23,352 lb. Because the tank is rated to 1.9 specific gravity, its maximum rated contents weight runs to roughly 44,369 lb, so you have real headroom to haul dense fertilizers, brines, and treatment chemicals rather than topping out at water weight. That 44,369 lb is the number your trailer deck, axles, and tow vehicle must be rated for, and because the load rides on molded legs rather than a full cradle, the frame has to handle that weight at the leg contact points, not just as a gross total. Size to the loaded figure, not the empty tank. Use our Tank Sizing Calculator and the Tank Sizing Guide to confirm capacity, fill weight, and footprint against your equipment before you buy.
Chemical compatibility
This tank is polyethylene with a 1.9 specific gravity rating. The resin is recorded as HDLPE on our data, but the trailing question mark means you must confirm HDLPE versus XLPE for this exact unit before placing it in chemical service - cross-linked and linear polyethylene behave differently with aggressive products, and for the harsher items on the list (sulfuric acid 98%, hydrochloric acid 37%, hydrofluoric acid 48%, peracetic acid) that confirmation is mandatory before you order. Call 866-418-1777 to verify the resin for your service. Fitting and gasket requirements are chemical-specific and range from PVC up to CPVC, 316SS, and Aflas or Viton seals, so do not assume PVC and EPDM cover your product. Every value below comes from the OEM chemical-resistance chart, which is concentration- and temperature-specific; match your fittings and gaskets to the chemical and verify the published rating for your exact concentration and operating temperature.
Products confirmed compatible with this resin and SG rating include acetic acid (60%, PP/PVC fittings, EPDM gasket), 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 (<16.5%, PVC, Viton), sodium thiosulfate (40%, PVC, EPDM), sulfuric acid (98%, CPVC, Viton), urea solution (50%, PP/PVC, EPDM), and zinc orthophosphate (PP/316SS, EPDM). See the full chemical compatibility resource and the OEM resistance chart for your exact concentration and temperature.
The mistake to avoid
The most common error on a tank this size is loading a heavy product without checking the specific gravity match. The 1.9 SG rating is a ceiling, not a suggestion: confirm your chemical's specific gravity sits at or below 1.9, and never push a higher-density product into it. Just as important, resolve the HDLPE versus XLPE question before any aggressive chemical goes in, and match fittings and gaskets exactly to the materials on the OEM chart rather than defaulting to PVC and EPDM. For weight transfer, ride the legs on a properly rated frame and review the technical drawing on this page for fitting locations and dimensions before you build your plumbing.
