The Enduraplas 800 Gallon Yellow Horizontal Leg Tank (SKU THF00800Y) is a low-slung polyethylene horizontal leg tank built to carry liquid down the road, not just sit on a pad. It measures 94 inches long by 60 inches wide by 48 inches high, and the wide 60-by-94-inch footprint plus integrated legs are what keep a full load stable in transit. Rated to a 1.9 specific gravity, this yellow Enduraplas horizontal tank is one of the heavier-duty leg tanks in the lineup, which is what lets it haul dense agricultural and water-treatment chemistries rather than water alone.
Will it work for your load?
Start with weight, because that is where horizontal haul tanks get people. Filled with plain water (SG 1.0), the contents alone weigh 6,672 lbs. At its full 1.9 SG rating the tank is engineered to carry up to 12,677 lbs of product. That is the number that matters: 12,677 lbs spread across a 60-by-94-inch footprint is the bearing load your saddle, frame, and axles have to be designed for, not the empty tank weight. Before you spec a trailer or skid, run those figures with the Tank Sizing Calculator and the Tank Sizing Guide so the structure is sized for the real loaded weight. Confirm fitting locations and outlet placement against the technical drawing on this page before you plumb it.
Chemical compatibility
For the yellow ag and fleet crowd, the headline loads are DEF (diesel exhaust fluid at 32.5%, which requires 316SS fittings and EPDM gaskets) and urea solution (50%, PP/PVC fittings, EPDM gaskets). Both pair cleanly with this tank when the hardware matches.
This is a high-1.9-SG polyethylene tank. The resin grade is not fully confirmed in our records, so confirm the exact polyethylene (HDLPE vs XLPE) with us before putting it into chemical service - it changes what you can safely store. The compatibilities below assume the standard high-density resin, and the strong-acid entries (sulfuric 98%, HF 48%, HCl 37%) are the ones most sensitive to resin grade, so verify those specifically before committing. All values are concentration-specific; check your exact concentration and operating temperature against the OEM chemical-resistance chart and confirm with us first.
Acids this tank can handle with the right hardware include acetic acid (60%, PP/PVC fittings, EPDM gaskets), hydrochloric acid (37%, PVC, Viton), hydrofluoric acid (48%, PP/PVC, Viton), hydrofluosilicic acid (26%, PP/PVC, Viton), phosphoric acid (85%, PVC, Viton), peracetic acid (30%, 316SS, Aflas), and sulfuric acid (98%, CPVC, Viton). Salts, glycols, and treatment chemistries are well covered: aluminum sulfate (50%, PVC/EPDM), calcium chloride (40%, PVC/EPDM), magnesium chloride (30%, PVC/EPDM), ferric chloride (50%, PVC/EPDM), ferric sulfate (60%, PVC/EPDM), ferrous sulfate (20%, PVC/EPDM), polyaluminum chloride (PVC/EPDM), ethylene glycol (100%, PVC/EPDM), and propylene glycol (PP/316SS, EPDM). Water-treatment and dosing chemistries include hydrogen peroxide (50%, PVC/Viton), sodium hypochlorite (under 16.5%, PVC/Viton), sodium carbonate (30%, PVC/EPDM), sodium bisulfate (PVC/PP, EPDM), sodium bisulfite (PVC/PP, EPDM), sodium thiosulfate (40%, PVC/EPDM), potassium carbonate (50%, PVC/EPDM), potassium hydroxide (saturated, PVC/EPDM), zinc orthophosphate (PP/316SS, EPDM), and ozonated water (up to 10 PPM, PVC/EPDM).
The single most expensive mistake is reusing one fitting and gasket spec across chemistries. Match each chemical to its own hardware: DEF and peracetic acid need 316SS; sulfuric at 98% needs CPVC, not the PVC that works for most others; HCl, HF, sulfuric, phosphoric, hydrogen peroxide, and sodium hypochlorite need Viton instead of EPDM.
