The Enduraplas 200 Gallon Yellow Horizontal Sump Bottom Leg Tank (SKU THD00200Y) is a 200-gallon polyethylene leg tank built for mobile and stationary chemical handling where you need a low-slung, free-standing footprint. It measures 47 inches wide by 55 inches long by 31 inches tall, sits on integrated legs, and drains toward a sump bottom for near-complete emptying. The yellow tank carries a 1.9 specific gravity rating, which is what lets it hold heavy chemical loads, not just water. This page covers whether it fits your job, how it ships, and the one mistake that ruins a leg-tank purchase.
Will it work for your application?
Footprint is 47.0 x 55.0 inches, so confirm it clears your trailer deck, skid, or pad before ordering. Filled with water, this 200 gallon tank weighs about 1,668 lb; at its full 1.9 specific gravity rating it can carry up to 3,169 lb of contents. That spread matters: water sizing and chemical sizing are two different weights, and your trailer, hitch, and tie-downs have to be rated for whichever fluid you actually haul. Use the Tank Sizing Calculator to translate gallons into the real loaded weight for your product, and the Tank Sizing Guide if you are deciding between this size and a larger horizontal leg tank. As a horizontal leg tank, it is purpose-built to sit on a deck or skid rather than stand vertically, and the sump bottom means it empties cleanly when you rotate products.
Chemical compatibility
The tank is molded from polyethylene and carries a 1.9 specific gravity rating. The resin classification on this model reads as HDLPE but is not yet confirmed, so confirm HDLPE versus XLPE for your service before putting any chemical in it — the resin determines which products are safe over the long term, and our team can resolve it at 866-418-1777. Compatibility below is drawn from the OEM chemical-resistance chart and is concentration- and temperature-specific; always match it to your actual product, fitting material, and gasket material.
With PVC fittings and EPDM gaskets, this tank suits Aluminum Sulfate (50%), Calcium Chloride (40%), Ethylene Glycol (100%), Ferric Chloride (50%), Ferric Sulfate (60%), Ferrous Sulfate (20%), Magnesium Chloride (30%), Potassium Carbonate (50%), Potassium Hydroxide (saturated), Sodium Carbonate (30%), and Sodium Thiosulfate (40%). Acid service shifts the gasket to Viton: Hydrochloric Acid (37%, PVC), Phosphoric Acid (85%, PVC), Sulfuric Acid (98%, CPVC), Hydrogen Peroxide (50%, PVC), and Sodium Hypochlorite (under 16.5%, PVC). Stronger acids call for PP or PVC fittings with Viton: Hydrofluoric Acid (48%) and Hydrofluosilicic Acid (26%). For Acetic Acid (60%) use PP/PVC fittings with EPDM. DEF and ag-fertilizer crews will note that a 1.9-SG-rated shell carries light fluids with large structural margin: DEF (32.5%, 316SS, EPDM) and Urea Solution (50%, PP/PVC, EPDM) both run well under the rated load. Also confirm concentration before ordering on chemicals the chart leaves unspecified: Propylene Glycol (PP/316SS, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), Polyaluminum Chloride (PVC, EPDM), Sodium Bisulfate (PVC/PP, EPDM), and Sodium Bisulfite (PVC/PP, EPDM). Peracetic Acid (30%) needs 316SS with Aflas, and Ozonated Water up to 10 PPM runs on PVC/EPDM. See the full chemical compatibility reference and match concentration and temperature to your exact product before committing.
The mistake to avoid
The error that costs people money on a leg tank like this is mismatching the fitting and gasket to the chemical even when the resin is fine. The polyethylene shell may tolerate your product, but the wrong gasket fails first: hydrochloric, phosphoric, sulfuric, hydrogen peroxide, and sodium hypochlorite all demand Viton rather than EPDM, while DEF and peracetic acid want stainless. Spec the fittings off the OEM chart, not by habit. If you are using this for fertilizer or ag service, the resources on applicator and leg tanks for fertilizer, portable utility tank DOT classification, and fertilizer-blend tank stratification are worth reading before you load.
