The Enduraplas 1400 Gallon Yellow Horizontal Leg Tank (SKU THF01400Y) is a 1,400-gallon transport-and-haul tank molded in yellow polyethylene with a 1.9 specific gravity rating, the top of the SG scale and the reason this tank can carry the dense agricultural and water-treatment liquids that would over-stress a standard 1.0 to 1.5 tank. It measures 66 in. high, 70 in. wide, and 102 in. long, riding on integrated legs that hold the cylinder stable on a trailer or skid. Full of water it carries 11,676 lb; loaded to its maximum rated contents weight it reaches 22,184 lb. Those numbers drive your axle, trailer, and tie-down decisions before the first load goes in.
Will this Enduraplas horizontal leg tank work for your haul?
This is a horizontal leg tank built for portability, the format farmers and applicators search for when they want a yellow horizontal tank that sits low and hauls without a full cradle. Its 70 x 102 in. footprint defines the deck space you need: at 102 in. the tank runs past the standard 96 in. (8 ft) trailer width, so confirm your deck length and tie-down geometry before you commit. Size your load against the weights above. At 1.9 SG the tank is rated to a maximum contents weight of 22,184 lb, but match the actual product density to your trailer and suspension rating rather than filling to the structural maximum. Run your fill scenario through the Tank Sizing Calculator and the Tank Sizing Guide to confirm gallons, weight, and footprint line up with your equipment. For DOT and trailer classification on agricultural haul tanks, the applicator and leg tank DOT scope guide and the agricultural exemption explainer walk through how these tanks are classified for farm fleet use.
Chemical compatibility
The resin designation for this tank is flagged with a question mark in our data, so confirm HDLPE versus XLPE with us before putting any chemical into service, because the two resins behave differently with aggressive products. Every service below is concentration- and temperature-specific per the OEM chemical-resistance chart, and the fitting and gasket materials listed are what each service requires. Most services run PVC fittings with EPDM gaskets: aluminum sulfate (50%), calcium chloride (40%), ethylene glycol (100%), ferric chloride (50%), ferric sulfate (60%), ferrous sulfate (20%), magnesium chloride (30%), polyaluminum chloride, potassium carbonate (50%), potassium hydroxide (saturated), sodium carbonate (30%), sodium thiosulfate (40%), sodium bisulfate (PVC/PP), sodium bisulfite (PVC/PP), acetic acid (60%, PP/PVC), urea solution (50%, PP/PVC), and ozonated water (up to 10 PPM).
Strong acids and oxidizers need Viton (or Aflas) elastomers, not EPDM: hydrochloric acid (37%, PVC/Viton), hydrofluoric acid (48%, PP/PVC/Viton), hydrofluosilicic acid (26%, PP/PVC/Viton), hydrogen peroxide (50%, PVC/Viton), phosphoric acid (85%, PVC/Viton), sodium hypochlorite (under 16.5%, PVC/Viton), sulfuric acid (98%, CPVC/Viton), and peracetic acid (30%, 316SS/Aflas). A few services require stainless rather than plastic fittings: DEF at 32.5% (316SS/EPDM), propylene glycol (PP/316SS/EPDM), and zinc orthophosphate (PP/316SS/EPDM) all run 316 stainless, which is a different fitting package and cost than PVC. Match fittings and gaskets to the exact product and concentration, and start at our chemical compatibility hub to verify before you order.
The mistake to avoid
The common error on a 1.9 SG haul tank is treating the rating as a fill target. The 22,184 lb maximum rated contents weight is a structural ceiling, not a loading recommendation; for dense fertilizer blends, watch how the liquid behaves over time, because stratification and salting-out can leave you spreading off-spec product. The fertilizer-blend stratification guide covers the mixing protocol and field checks that catch a stratified tank before the spreader runs off-spec. And because the resin grade is flagged in our records, confirm HDLPE versus XLPE with us before any chemical fill. Review the technical drawing on this page for fitting locations and dimensional detail.
This tank ships LTL freight from the Enduraplas plant in Neche, ND, quoted live to your ZIP. Because Neche is a single far-northern plant near the Canadian border, distance drives the rate, so run your delivery ZIP through the Freight Cost Estimator early.
