The Enduraplas 150 Gallon Green Horizontal Sump Bottom Leg Tank is a 150-gallon polyethylene horizontal leg tank built for portable haul work — moving water, DEF, or chemical loads on a trailer, in a truck bed, or on a skid. Its sump bottom and integrated legs give it a stable 41.0 x 46.0 inch footprint, and the body measures 33 inches high, 41 inches wide, and 46 inches long. The green polyethylene carries a 1.9 specific gravity rating, which is what makes this tank usable for dense liquids well beyond plain water.
Will it work for your load — and what will it cost to ship?
Sizing is where horizontal leg tanks get people. At 150 gallons of plain water this tank holds roughly 1,251 pounds; loaded to its full 1.9 specific gravity rating it carries up to 2,377 pounds of contents. That spread matters two ways: a fertilizer blend or chemical concentrate weighs far more than the same volume of water, so you rate your vehicle, tie-downs, and suspension against the heavy 2,377 lb number — and that same weight drives the LTL freight class. Because this tank ships from a single plant in Neche, ND, price the haul to your ZIP early with the Freight Cost Estimator before you commit. Run the load weights through the Tank Sizing Calculator and the Tank Sizing Guide first. If you are moving agricultural fertilizer on a non-roadable trailer, the scope rules are worth reading — see our guides on applicator and leg tanks for fertilizer and the 49 CFR agricultural exemption and DOT classification for farm fleet use.
Chemical compatibility
This is a polyethylene tank with a 1.9 specific gravity rating, so it has real headroom for heavy chemical and density-driven haul liquids — DEF and urea-based blends are exactly the dense loads this leg tank is built to carry. Before you put any chemical into service, confirm the resin with us: our data lists it as HDLPE but unconfirmed, and HDLPE versus XLPE changes what you can store. The compatibility, fitting material, and gasket material below are concentration- and temperature-specific; match your exact concentration and operating temperature before ordering.
Documented compatible chemicals for this tank include acetic acid (60%), aluminum sulfate (50%), calcium chloride (40%), DEF (32.5%, 316SS fittings), ethylene glycol (100%), ferric chloride (50%), ferric sulfate (60%), ferrous sulfate (20%), hydrochloric acid (37%, Viton gasket), hydrofluoric acid (48%, Viton gasket), hydrofluosilicic acid (26%, Viton gasket), hydrogen peroxide (50%, Viton gasket), magnesium chloride (30%), peracetic acid (30%, 316SS fittings, Aflas gasket), phosphoric acid (85%, Viton gasket), polyaluminum chloride, potassium carbonate (50%), potassium hydroxide (saturated), propylene glycol (PP/316SS fittings), sodium bisulfate, sodium bisulfite, sodium carbonate (30%), sodium hypochlorite (<16.5%, Viton gasket), sodium thiosulfate (40%), sulfuric acid (98%, CPVC fittings, Viton gasket), urea solution (50%), zinc orthophosphate (PP/316SS fittings), and ozonated water (up to 10 PPM). Note the chlorinated and oxidizing chemicals — hydrochloric acid, hydrofluoric acid, hydrogen peroxide, phosphoric acid, sodium hypochlorite, sulfuric acid — call for Viton gaskets rather than EPDM, and a few require 316 stainless or CPVC hardware. Getting the gasket and fitting material wrong is the most common, and most expensive, mistake on a chemical tank. Cross-check every selection against our full chemical compatibility reference; if you are blending fertilizer, our guide on fertilizer-blend tank stratification covers the mixing physics that catch an off-spec batch.
The mistake to avoid
The 1.9 specific gravity rating is the headline number, but it is a maximum, not a license to ignore it. If your chemical's specific gravity exceeds 1.9, this tank is the wrong choice — call us at 866-418-1777 for a higher-SG recommendation before you order. Two other points to confirm: the resin code, as noted above, and the fitting configuration — outlet size and bulkhead locations are not specified in our data, so call to confirm them for your liquid. See the technical drawing on this page for dimensional detail.
