The Enduraplas 1100 Gallon Green Horizontal Leg Tank is a polyethylene haul tank built to ride in a steel saddle or trailer frame and move liquid down the road or across the field. It holds 1,100 gallons in a horizontal body measuring 94 inches long, 60 inches wide, and 63 inches tall, with full molded legs that cradle the tank and keep the load stable in transit. The green poly shell carries a 1.9 specific gravity rating, which is what makes this an Enduraplas horizontal leg tank you can put under heavy ag and industrial liquids rather than just water.
Will it handle your load?
Weight is the first thing to check on any horizontal leg tank. Filled with water, this tank runs about 9,174 pounds. Because the shell is rated to 1.9 specific gravity, the maximum rated contents weight climbs to roughly 17,431 pounds when you fill it with a dense liquid such as a fertilizer blend or brine. Size your trailer, frame, and tie-downs for that loaded figure, not the empty tank. The 60-by-94-inch footprint tells you how much deck the tank needs and where the legs land. If you are matching tank size to job, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you commit to a frame. This listing does not include pre-set fittings — outlet and vent fittings are configured to your job, so the fitting materials below are compatibility guidance, not included hardware.
Chemical compatibility
This is a polyethylene tank (HDLPE) with a 1.9 specific gravity rating, the highest density rating offered for this body — there is no heavier-duty version, so this is the tank for dense liquids. Because the resin code carries a question mark in our records, confirm HDLPE versus XLPE construction before chemical service, since the two resins behave differently with aggressive chemistries. That confirmation matters most for the harsh acids on the list below, such as sulfuric, hydrofluoric, and peracetic, and far less for water, glycol, or brine. The fitting and gasket materials below come from the OEM chemical-resistance chart and are concentration and temperature specific, so always verify against the published chart for your exact conditions.
Compatible chemicals include Acetic Acid at 60% (PP/PVC fittings, EPDM gaskets), Aluminum Sulfate at 50% (PVC, EPDM), Calcium Chloride at 40% (PVC, EPDM), DEF at 32.5% (316SS, EPDM), Ethylene Glycol at 100% (PVC, EPDM), Ferric Chloride at 50% (PVC, EPDM), Ferric Sulfate at 60% (PVC, EPDM), Ferrous Sulfate at 20% (PVC, EPDM), Hydrochloric Acid at 37% (PVC, Viton), Hydrofluoric Acid at 48% (PP/PVC, Viton), Hydrofluosilicic Acid at 26% (PP/PVC, Viton), Hydrogen Peroxide at 50% (PVC, Viton), Magnesium Chloride at 30% (PVC, EPDM), Peracetic Acid at 30% (316SS, Aflas), Phosphoric Acid at 85% (PVC, Viton), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate at 50% (PVC, EPDM), Potassium Hydroxide saturated (PVC, EPDM), Propylene Glycol (PP/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), Sodium Carbonate at 30% (PVC, EPDM), Sodium Hypochlorite under 16.5% (PVC, Viton), Sodium Thiosulfate at 40% (PVC, EPDM), Sulfuric Acid at 98% (CPVC, Viton), Urea Solution at 50% (PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water up to 10 PPM (PVC, EPDM, per the OEM chart — no dedicated page yet, so call for specifics). Watch the metal and CPVC exceptions: DEF and Peracetic Acid both need 316SS fittings, Sulfuric Acid 98% needs CPVC, and Peracetic Acid is the only chemistry here that calls for an Aflas gasket. That is the mistake to avoid: the tank may accept the liquid, but the wrong fitting or gasket fails before the tank does. Match every fitting and seal to the chemical you are running, and cross-check each against its dedicated page and our full chemical compatibility resource.
Mounting and matching the tank
As a horizontal leg tank, this Enduraplas body is meant to sit in a steel saddle or frame and travel. If you are spec'ing it for fertilizer or applicator duty, our guides on applicator and leg tanks for fertilizer and portable utility tanks under the agricultural exemption walk through DOT scope and farm-fleet classification. If you are blending, the deep-dive on fertilizer-blend tank stratification covers thermal layering and the mixing protocols that keep your spreader on-spec. See the technical drawing on this page for the leg spacing and fitting layout to confirm against your frame.
This tank ships LTL freight from the Enduraplas plant in Neche, ND, with freight quoted live to your ZIP. Use our Freight Cost Estimator for a freight estimate, or call 866-418-1777 and we will work the freight and fitting package with you. From horizontal leg tanks to full applicator setups, we will match the tank to your haul.
