The Enduraplas 1100 Gallon White Horizontal Leg Tank is a polyethylene horizontal leg tank built for hauling dense liquid where you need it, then setting it down level on a self-supporting footprint. It holds 1,100 gallons in a natural white shell that measures 94 inches long by 60 inches wide by 63 inches tall, with integrated legs that keep it stable on a trailer deck or skid. The 1.9 specific gravity rating is the headline spec here, and it is the highest rating offered in this horizontal leg tank family, so there is no heavier-rated step-up to chase if your product is dense.
Will it work for your job?
Capacity is the first checkpoint; the weight that capacity puts under load is the second. Filled with water this tank carries roughly 9,174 pounds of contents, and at its full 1.9 specific gravity rating it is engineered to carry up to 17,431 pounds of dense liquid. That 17,431-pound max-rated figure is the number that sizes everything downstream: your axles, tongue weight, tow vehicle, and the deck or skid it sits on. The footprint is 60 inches wide by 94 inches long (W x L) - confirm it drops onto your existing deck before you commit. If you are not sure 1,100 gallons fits your acreage, route distance, or fill schedule, run the numbers with our Tank Sizing Calculator and the Tank Sizing Guide. Fitting sizes and locations - outlet, fill, and vent - are confirmed off the technical drawing on this page and by phone before you plumb it, so call us with your plumbing plan rather than guessing the outlet size.
Chemical compatibility
This is a polyethylene tank rated to 1.9 specific gravity, which is what lets it hold heavy chemical solutions and not just water. The resin designation in our records is shown as HDLPE but is not yet confirmed, so confirm HDLPE versus XLPE for your specific service before storing aggressive chemistry. Compatibility is always concentration- and temperature-specific: check the OEM chemical-resistance chart for your exact product and match the fitting and gasket material to it. Suited chemistries include acetic acid (60%, PP/PVC fittings, EPDM gaskets), aluminum sulfate (50%, PVC, EPDM), calcium chloride (40%, PVC, EPDM), DEF (32.5%), ethylene glycol (100%, PVC, EPDM), ferric chloride (50%, PVC, EPDM), magnesium chloride (30%, PVC, EPDM), sodium carbonate (30%, PVC, EPDM), potassium hydroxide (saturated, PVC, EPDM), and urea solution (50%, PP/PVC, EPDM). The chemical compatibility hub covers the full list, including ferric sulfate, ferrous sulfate, hydrofluoric and hydrofluosilicic acids, polyaluminum chloride, sodium bisulfate, sodium bisulfite, sodium thiosulfate, potassium carbonate, propylene glycol, zinc orthophosphate, and ozonated water (up to 10 PPM).
The mistake to avoid: match the elastomer, not just the resin
The most common error on a horizontal leg tank in chemical service is matching fittings and gaskets to water instead of to the product. Standard EPDM gaskets cover most salts and bases, but the high-risk chemistries need specific materials, and the wrong elastomer fails long before the tank does. Three callouts worth committing to memory: oxidizers and strong acids need Viton gaskets - sulfuric acid (98%) on CPVC fittings, hydrochloric acid (37%), hydrogen peroxide (50%), phosphoric acid (85%), sodium hypochlorite (under 16.5%), and hydrofluoric and hydrofluosilicic acids all on Viton; DEF demands 316SS fittings; and peracetic acid (30%) needs both 316SS fittings and an Aflas gasket. Verify the resin and the gasket for your exact chemical and concentration before the first fill. If you are blending fertilizer, our guides on applicator and leg tanks for fertilizer and fertilizer-blend tank stratification are worth reading first, and the loaf-style portable utility tank guide covers the DOT and agricultural-exemption questions that come with hauling.
