The Enduraplas 250 Gallon Green Horizontal Sump Bottom Leg Tank is a polyethylene transport tank built for moving liquid by trailer or truck. It carries 250 gallons across a 37 in. tall body that measures 47 in. wide by 55 in. long, putting the tank on a 47.0 x 55.0 in. footprint. The molded legs give the horizontal body a stable seat on a skid or trailer deck, and this green Enduraplas horizontal leg tank is rated to a 1.9 specific gravity, which is what lets it haul liquids substantially heavier than water. See the technical drawing on this page for the sump and outlet location before you plumb the tank.
Will it work for your load
Filled with water, this tank weighs about 2,085 lb. Because it carries a 1.9 specific gravity rating, the maximum rated contents weight climbs to roughly 3,962 lb when you fill it with a dense liquid such as a fertilizer blend or a heavy chemical concentrate. That 1.9 rating is real headroom: a standard 1.5-SG tank in this same 250 gallon body tops out around 3,127 lb of contents, so the heavier rating is what you are paying for when you need to move dense liquids. Size your trailer, hitch, and tie-downs to the loaded number, not the empty tank, and confirm your contents' specific gravity before you fill. If you are unsure how this 250 gallon size maps to your haul cycle, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide.
Chemical compatibility
This Enduraplas tank is molded from polyethylene at a 1.9 specific gravity rating. The resin is recorded as HDLPE but not yet confirmed - verify whether your tank is HDLPE or crosslinked (XLPE) with us before you put it into any chemical service, because the resin, not the SG rating, governs what it can safely hold. The chemicals below come from the OEM chemical-resistance chart and are concentration- and temperature-specific, so match your actual concentration and operating temperature to the chart before committing:
- Acetic Acid (60%) - PP/PVC fittings, EPDM gaskets - details
- Aluminum Sulfate (50%) - PVC fittings, EPDM gaskets - details
- Calcium Chloride (40%) - PVC fittings, EPDM gaskets - details
- DEF (32.5%) - 316SS fittings, EPDM gaskets - details
- Ethylene Glycol (100%) - PVC fittings, EPDM gaskets - details
- Ferric Chloride (50%) - PVC fittings, EPDM gaskets - details
- Ferric Sulfate (60%) - PVC fittings, EPDM gaskets - details
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets - details
- Hydrochloric Acid (37%) - PVC fittings, Viton gaskets - details

- Sodium Bisulfate - PVC/PP fittings, EPDM gaskets - details
- Sodium Bisulfite - PVC/PP fittings, EPDM gaskets - details
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets - details
- Sodium Hypochlorite (under 16.5%) - PVC fittings, Viton gaskets - details
- Sodium Thiosulfate (40%) - PVC fittings, EPDM gaskets - details
- Sulfuric Acid (98%) - CPVC fittings, Viton gaskets - details
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets - details
- Zinc Orthophosphate - PP/316SS fittings, EPDM gaskets - details
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
Notice that fitting and gasket material change by chemical - acids like hydrochloric, sulfuric, and phosphoric call for Viton seals, while DEF and peracetic acid call for 316 stainless. The most common mistake on a tank like this is matching the right resin but pairing it with the wrong gasket, so spec your fittings and seals against the chemical you are actually hauling.

Freight and ordering
This horizontal leg tank ships LTL from the Enduraplas plant in Neche, ND, with freight quoted live to your ZIP code. Your quote and class are driven by the loaded weight - figure roughly 2,085 lb with water and up to about 3,962 lb with dense contents - so have that number ready or pull a live estimate from our Freight Cost Estimator, or call us at 866-418-1777. If you are hauling fertilizer or running a non-roadable trailer setup, our guides on applicator and leg tanks for fertilizer and fertilizer-blend tank stratification walk through the DOT scope and mixing physics that matter for a horizontal transport tank.
