The Enduraplas 100 Gallon Yellow Horizontal Sump Bottom Leg Tank arrives with its leg frame and is built for the road: a horizontal poly body cradled in a frame so it rides flat on a truck bed, trailer, or skid for field transfer of water and farm chemistry. The yellow polyethylene shell measures 46 inches long by 41 inches wide by 28 inches tall, holds 100 gallons, and carries a 1.9 specific gravity rating - it is engineered for dense liquids well above the weight of water, which is what separates a haul-rated chemical tank from a plain water caddy. Filled with plain water the contents weigh about 834 pounds; the 1.9 SG rating raises the safe ceiling to roughly 1,585 pounds of product, so you can plan trailer axle load against both the everyday and the maximum number.
Will it work for your liquid and your rig?
Match the load to the rating before you fill it. The sump bottom drains toward the outlet so you empty the tank cleanly instead of leaving product pooled at the floor, and the 41 x 46 inch footprint plus the 28-inch overall height (frame and legs included) tell you both the deck space and the clearance the tank needs on your trailer, under a doorway, or against a rail. Confirm your actual liquid's weight against that 1,585 pound ceiling using the Tank Sizing Calculator and the Tank Sizing Guide before loading, especially if you are stepping up from a lighter water-only setup. Outlet and fitting sizes are not published in our data, so confirm the exact port size and thread before you order chemical fittings - and see the technical drawing on this page for port and fitting locations.
Chemical compatibility
This is a 1.9 specific-gravity polyethylene tank. Our resin record lists it as HDLPE but flags an open question on grade, so confirm HDLPE versus XLPE (cross-linked) with us before committing it to chemical service - the two resins behave very differently against certain chemistries. The OEM chemical-resistance chart is concentration- and temperature-specific, so verify your exact concentration and service temperature before filling. Within that chart, this tank pairs with a wide range of agricultural and water-treatment chemistry, including DEF (diesel exhaust fluid) at 32.5% using 316 stainless fittings and EPDM gaskets, urea solution at 50% with PP or PVC fittings and EPDM gaskets, calcium chloride at 40% and magnesium chloride at 30% (PVC/EPDM), aluminum sulfate at 50%, ferric chloride at 50%, ferric sulfate at 60%, ferrous sulfate at 20%, ethylene glycol at 100%, and sodium carbonate at 30%. For aggressive acids the gasket choice changes to Viton: hydrochloric acid at 37%, phosphoric acid at 85%, hydrogen peroxide at 50%, hydrofluoric acid at 48%, and sodium hypochlorite below 16.5% with PVC fittings, while sulfuric acid at 98% calls for CPVC fittings and Viton. The chart also covers acetic acid at 60%, hydrofluosilicic acid at 26%, peracetic acid at 30% (316SS, Aflas gasket), potassium carbonate at 50%, potassium hydroxide (saturated), propylene glycol, sodium bisulfate, sodium bisulfite, polyaluminum chloride, sodium thiosulfate at 40%, zinc orthophosphate, and ozonated water up to 10 PPM. Always match the fitting and gasket material to your specific chemical, and see our full chemical compatibility reference.
The mistake to avoid
The most common error on a haul-rated leg tank is loading it as if it were water. The 1.9 SG rating is the whole point of this tank, but it is not a license to ignore your fittings: DEF demands 316 stainless, the strong acids demand Viton or Aflas gaskets and CPVC on concentrated sulfuric, and the wrong fitting metal or elastomer will fail long before the poly body does. Pair the right fitting and gasket to your chemical, keep your filled weight under the 1,585 pound rating, and resolve the open resin-grade question with us first - that one phone call prevents the costliest mistake of all. A 100 gallon horizontal leg tank for a transport rig is exactly where this Enduraplas model fits.
