The Enduraplas 200 Gallon White Horizontal Sump Bottom Leg Tank (SKU THD00200W) is a 200-gallon polyethylene tank built for transport on a trailer or skid: a low 31-inch profile, a 47-by-55-inch footprint, and integrated legs that let it sit and haul stable. Molded from Enduraplas polyethylene in natural white, it carries a 1.9 specific gravity rating, so it is engineered to haul liquids heavier than water. Per the model name it has a sump bottom for end-of-run draining at the low point.
Does it work for your load?
Sizing matters more than gallons on a leg tank, because what you haul has weight. Filled with water, this 200-gallon horizontal leg tank carries about 1,668 pounds. At its 1.9 specific gravity rating, the maximum rated contents weight is 3,169 pounds, so the tank shell itself is rated for dense fluids such as fertilizer blends and brines. Confirm your trailer, hitch, and tie-downs are rated for the loaded weight you actually intend to move, and check the 47.0 x 55.0-inch footprint against your deck. The technical drawing on this page shows the port and sump layout. If you are deciding between sizes, run the numbers in our Tank Sizing Calculator and read the Tank Sizing Guide.
Chemical compatibility
This tank is polyethylene with a 1.9 specific gravity rating. The resin in our data is recorded as HDLPE with a question mark, so before any chemical service confirm whether this shell is HDLPE or XLPE with us at 866-418-1777, because that distinction governs whether the rating holds. This matters most for the aggressive chemistries below: sulfuric acid at 98% (CPVC, Viton), hydrofluoric acid at 48% (PP/PVC, Viton), peracetic acid at 30% (316SS, Aflas), hydrogen peroxide at 50% (PVC, Viton), and sodium hypochlorite below 16.5% (PVC, Viton). Compatibility data here is drawn from the OEM chemical-resistance chart and is concentration- and temperature-specific; match it to your exact service conditions.
Within the 1.9 SG rating, this tank suits a wide range of chemistries. Other acids include acetic acid at 60% (PP/PVC, EPDM), hydrochloric acid at 37% (PVC, Viton), hydrofluosilicic acid at 26% (PP/PVC, Viton), and phosphoric acid at 85% (PVC, Viton). Coagulants and salts include aluminum sulfate at 50%, ferric chloride at 50%, ferric sulfate at 60%, ferrous sulfate at 20%, calcium chloride at 40%, magnesium chloride at 30%, and polyaluminum chloride, all on PVC with EPDM. Bases and treatment chemistries include sodium carbonate at 30%, potassium carbonate at 50%, potassium hydroxide (saturated), sodium bisulfate, sodium bisulfite, sodium thiosulfate at 40%, and zinc orthophosphate, mostly on PVC or PP with EPDM. Ozonated water up to 10 PPM (PVC, EPDM) is rated on the OEM chart; we do not yet have a dedicated reference page for it.
For ag and fluid-handling fleets, the tank also takes DEF at 32.5% (316SS, EPDM) and urea solution at 50% (PP/PVC, EPDM), plus ethylene glycol at 100% (PVC, EPDM) and propylene glycol (PP/316SS, EPDM). Match fitting and gasket materials to the chemical you are running, and start with the full chemical compatibility reference before specifying ports. Note that our catalog does not list published port or sump-outlet sizes for this tank, so confirm fitting dimensions and locations at order time by calling 866-418-1777, especially for chemical service where the fitting material has to match a known port size.
The mistake to avoid
The error that catches buyers on leg tanks is treating them like water tanks. The 1.9 specific gravity rating is the ceiling, not a suggestion: at 200 gallons, dense fertilizer blends approach the 3,169-pound rated maximum, and a blend that stratifies or salts out can shift weight and concentration mid-haul. Read our guide on fertilizer-blend stratification before you fill, and if this is a roadable or applicator setup see applicator and leg tank DOT scope and the Norwesco loaf-style portable utility tanks and 49 CFR agricultural exemption guide.
