The Enduraplas 2200 Gallon Black Horizontal Sump Bottom Leg Tank (SKU THD02200B) is a polyethylene horizontal leg tank built for hauling dense liquids over the road and across the field. It measures 130 inches long by 71 inches wide by 75 inches tall and carries a 1.9 specific gravity rating - the highest density rating offered in this leg-tank line. Black resin blocks UV and suppresses algae, which is why this tank shows up in searches for an Enduraplas horizontal leg tank for road and field work.
Freight first: this is a 17-ton loaded haul
Because the service question on a tank this size is "what will it cost to get here," start there. Filled with water the 2200-gallon body carries about 18,348 pounds, and at the 1.9 SG rating the structure is rated for up to roughly 34,861 pounds of contents - notice that 34,861 divided by 18,348 is almost exactly 1.9, so the rated number is the SG rating in pounds, verified by the arithmetic. That makes this a genuinely large LTL item on a 71 x 130 inch footprint, shipping from a single plant in Neche, ND.

Will it carry your load?
Sizing matters more on a hauling tank than on anything stationary, because the weight rides on your trailer and your axles. The roughly 16,500-pound gap between full-water weight and the rated contents weight is your usable density headroom - that is what lets you haul liquids heavier than water without overstressing the wall. Plan your trailer, suspension, and tie-downs around the loaded number, not the empty one, and run your dimensions and weights through the Tank Sizing Calculator and the Tank Sizing Guide before you commit.
Chemical compatibility
The resin code for this body carries a question mark in our data, and the 1.9 SG rating is itself the reason to confirm it: linear polyethylene (HDLPE) typically tops out well below 1.9, so a 1.9 rating points toward crosslinked (XLPE). Confirm HDLPE versus XLPE with us at 866-418-1777 before putting any chemical into service - the two behave differently with aggressive media. Compatibility is always concentration- and temperature-specific; verify your exact conditions against the OEM chemical-resistance chart and our per-chemical pages before ordering fittings or gaskets.
The rule of thumb across our chart for this body: EPDM gaskets cover most salts, hydroxides, and glycols; Viton handles the strong acids and oxidizers; and peracetic acid steps up to Aflas. Examples, with their fitting and gasket pairings, include acetic acid (60%, PP/PVC, EPDM), 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). See the full chemical compatibility reference and match your materials to the chemical, not to a default.
The mistake to avoid
The common error on a high-SG haul tank is fitting the gasket to the tank instead of to the liquid. The 1.9 SG body will hold an aggressive load, but the wrong elastomer at the bulkhead will fail long before the wall does - hydrochloric acid, hydrogen peroxide, and sulfuric acid all call for Viton, while DEF and peracetic acid step up to 316SS or Aflas. Confirm the resin (HDLPE versus XLPE) for your media, then spec fittings and gaskets off the per-chemical guidance above.
