The Enduraplas 250 Gallon Yellow Horizontal Sump Bottom Leg Tank is a horizontal transport and field tank built for chemical and fertilizer haul work where the load has to ride low. The 250-gallon body measures 55 inches long by 47 inches wide by 37 inches tall and rides on integrated legs, and the sump-bottom design slopes the floor to a low drain point so you can pull product down to the dregs instead of leaving heel in the tank. Molded from polyethylene in high-visibility yellow with a 1.9 specific gravity rating, this horizontal leg tank is rated for dense chemical and ag liquids that would overload a standard 1.0 to 1.5 SG tank.
Will it work for your load?
Size the tank to the weight of what you are hauling, not just the gallons. Full of water this tank carries about 2,085 lb, and the 1.9 SG rating allows a maximum rated contents weight of roughly 3,962 lb. Use those two numbers as your fenceposts: most field chemicals and fertilizer blends fall between them, so confirm your product's specific gravity, multiply by 250 gallons, and stay under the 3,962 lb ceiling. The 47 x 55 inch footprint is what you plan your mount around. Run those figures through the Tank Sizing Calculator or read the Tank Sizing Guide before you commit to a frame. At 1.9 SG this tank already sits at the top of the rating ladder, so no heavier-rated tank is needed for any chemical on the chart below. One spec the listing does not carry is a factory outlet or bung size, and no fitting ships with the tank by default, so call 866-418-1777 to confirm the sump outlet size and order plumbing to match.
Chemical compatibility
This is a polyethylene tank with a 1.9 specific gravity rating. The resin is listed as HDLPE but the grade is not fully confirmed, so verify HDLPE versus XLPE construction before putting it into chemical service - crosslinked and linear polyethylene resist different chemistries. Compatibility below is drawn from the manufacturer's chemical-resistance chart, which is concentration- and temperature-specific; always match your exact product, concentration, and operating temperature against the OEM chart before filling.
Chemicals this tank's 1.9 SG rating can carry, with the recommended fitting and gasket materials, include 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). Notice the fitting metal changes with the chemistry - DEF and peracetic acid call for 316 stainless, while the strong acids want Viton over EPDM gaskets. The full concentration- and temperature-specific picture lives in the OEM chemical-resistance chart and our chemical compatibility reference.
Built for the haul
This is a leg tank meant to ride on a trailer or truck bed, so plan the regulatory side along with the load. If you are moving fertilizer or ag chemicals on the road, read how the agricultural exemption and DOT classification work in our guide on 49 CFR 173.5 portable utility tank scope. If you are blending fertilizer, density-driven stratification can leave the spreader running off-spec; the field-verification methods in our fertilizer-blend stratification guide catch a stratified tank before it costs you. For applicator and leg-tank context, see our overview of applicator and leg tanks for fertilizer.
The mistake to avoid
The most expensive error on a tank like this is matching the gasket and fitting to the tank instead of to the chemical. The polyethylene body handles all the chemistries above, but a fitting in the wrong material or an EPDM gasket where the chart calls for Viton or Aflas will be the part that fails first - on sodium hypochlorite, sulfuric, phosphoric, and the peroxide/peracetic group especially. Lock down the fitting and gasket materials from the chart before you order any plumbing. And do not read the 1.9 SG rating as headroom to fill heavier; 3,962 lb of rated contents is the hard ceiling.
This Enduraplas horizontal leg tank ships LTL freight from the Enduraplas plant in Neche, ND, quoted live to your ZIP. Because it ships from that single northern-border origin, Western and Southern buyers should price the haul early - get your number in seconds with the Freight Cost Estimator, or call 866-418-1777 to confirm the sump outlet size and fitting materials for your chemical before you order.
