The Enduraplas 3200 Gallon Yellow Horizontal Leg Tank (SKU THF03200Y) is a transport-built polyethylene tank rated to 1.9 specific gravity, engineered to haul dense agricultural and industrial liquids that would overstress a tank rated below 1.9 SG. The leg-supported horizontal design keeps the load low and stable on a trailer or skid, making this a workhorse for fertilizer, brine, and heavy-chemical hauling where the freight ground truth is weight, not water volume.
Will it work for your load?
This Enduraplas yellow horizontal leg tank holds 3,200 gallons and measures 79 inches high, 97 inches wide, and 145 inches long, for a 97.0 x 145.0 inch footprint. The two weights that drive your rig decision are simple:
Water fill: 26,688 lb. Max rated at 1.9 SG: 50,707 lb.
That 50,707 lb ceiling works out to roughly 15.85 lb per gallon, meaning you can fill all 3,200 gallons of any compatible liquid up to 1.9 SG and still stay within the shell's rating — the SG rating and the volume are not in tension at this size. The 1.9 SG rating is the headline spec for anyone moving a heavy horizontal or leg tank load. Match your liquid's specific gravity against that 1.9 ceiling before you fill, and size the supporting trailer, axles, and tie-downs to the loaded weight, not the empty shell. Run your target volume through our Tank Sizing Calculator and Tank Sizing Guide to confirm the gallons and weight fit your rig. See the technical drawing on this page for dimensioned views.
Chemical compatibility
This tank is molded from polyethylene and carries a 1.9 specific-gravity rating. The exact resin designation is not fully confirmed in our data, so confirm high-density linear (HDLPE) versus crosslinked (XLPE) construction with us at 866-418-1777 before committing this tank to demanding chemical service. The compatibility table below is drawn from the OEM chemical-resistance chart, which is concentration- and temperature-specific; verify your exact concentration and operating temperature against that chart before storage.

The mistake to avoid
The costly error on a 1.9 SG leg tank is treating the fitting and gasket as an afterthought. Most chemicals here pair with PVC fittings and an EPDM or Viton gasket, but four entries break that default and trap buyers who order standard hardware: DEF (316SS / EPDM), Peracetic Acid (316SS / Aflas), Propylene Glycol and Zinc Orthophosphate (PP/316SS). Aflas on Peracetic Acid in particular is a gasket nobody stocks by accident. Aggressive acids — Hydrochloric, Hydrofluoric, Phosphoric, Sulfuric, and Sodium Hypochlorite — call for Viton (with CPVC on concentrated sulfuric). Putting an EPDM gasket on a Viton-spec acid, or PVC fittings where stainless is called for, is the failure that ends in a leak well before the tank itself ever wears out. For ag and fleet hauling context, our guides on applicator and leg tanks for fertilizer, portable utility tanks and DOT classification, and fertilizer-blend tank stratification walk through the field details.
