The Enduraplas 1400 Gallon Black Horizontal Sump Bottom Leg Tank (SKU THD01400B) is a 1,400-gallon polyethylene horizontal leg tank built for transport and field service. The integrated legs and sump bottom let it sit stable on a trailer or skid and drain through the low point, which is what you want when you are hauling chemical or fertilizer between fill site and field. It measures 102 inches long by 70 inches wide by 70 inches high, with a 70.0 x 102.0 inch footprint, and carries a 1.9 specific gravity rating - the reason this tank can hold denser chemistry than a 1.0 or 1.5 SG-rated tank.
Will it work for your load?
Full of water this tank weighs about 11,676 pounds, and at its maximum rated contents it carries up to 22,184 pounds. Use those two numbers when you spec the trailer, axles, and tie-downs - the gap between water weight and the 22,184 lb maximum rated weight is the room the 1.9 SG rating buys you for heavier-than-water liquids. If you are still deciding on capacity or how the loaded weight pencils out against your equipment, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you commit. Confirm the fill, vent, sump-drain, and lid configuration against the technical drawing on this page so the plumbing matches your pump and fill setup.
Chemical compatibility
This is a polyethylene tank with a 1.9 specific gravity rating. The resin designation carries a question mark in our records, so confirm whether this shell is HDLPE or XLPE with us at 866-418-1777 before you put aggressive chemistry in it - that single answer changes which acids are safe for long-term storage. The chemicals below are compatible at the listed concentrations, each paired with the fitting and gasket material it requires. Pay attention to those pairings: the chemicals calling for Viton, Aflas, or 316 stainless hardware - sulfuric acid, peracetic acid, DEF, and the strong oxidizers - will fail at the connection if you run standard EPDM gaskets or basic PVC fittings, even though the tank wall itself is fine. Always check the manufacturer's chemical-resistance chart for your specific concentration and temperature before service.

See the full chemical compatibility reference for concentration- and temperature-specific guidance, and remember that fitting and gasket material matters as much as the tank wall - the wrong elastomer is the most common reason a chemical tank fails at the connection, not the shell.
Freight
This tank ships LTL freight from Neche, ND - the named plant for this Enduraplas horizontal leg tank - and freight is quoted live to your ZIP. At roughly 11,676 pounds full and a 70 x 102 inch footprint, the shipping weight and dimensions are what set your freight class, so get a real number before you order. Use the Freight Cost Estimator for an instant quote to your delivery ZIP, or call us at 866-418-1777 and we will work the rate and the right tank for your load. For the regulatory side of hauling fertilizer and chemical in leg and applicator tanks, see our guides on applicator and leg tanks for fertilizer and DOT classification for farm fleet use, plus the fertilizer-blend tank stratification guide if you are mixing on site.
