The Enduraplas 2200 Gallon Black Horizontal Leg Tank is built for hauling dense liquid down the field road and across the yard. At 130 inches long, 71 inches wide, and 72 inches tall, it carries a 2,200-gallon load in a black polyethylene shell rated to a 1.9 specific gravity - the high SG rating is what separates a real chemical and fertilizer haul tank from a plain water hauler. The integrated leg design cradles the tank on a trailer or skid, and the black resin shields the contents from UV and sunlight-driven algae growth. At a 1.9 SG rating this is already the top density class we carry in this configuration, so there is no heavier-duty tank to step up to - your sizing decisions here are about trailer and axle capacity, not finding a denser tank. If you are weighing this Enduraplas horizontal leg tank against other horizontal tank sizes, the numbers below tell you exactly what it will and will not do.
Will it work for your load?
Capacity is 2,200 gallons in a footprint of 71.0 x 130.0 inches. Filled with water, the tank and contents weigh roughly 18,348 lb; loaded to the full 1.9 SG rating, total contents weight reaches 34,861 lb. That is a spread of about 16,500 lb - loading to the full rating adds the weight of a second loaded tank over a plain water fill, so a trailer or skid sized for water will be roughly 90% under-rated for a dense fertilizer or chemical haul. Those two numbers drive every decision around this tank: your trailer rating, axle count, and the ground or skid it sits on all have to carry the loaded weight, not the empty shell. Use the Tank Sizing Calculator and the Tank Sizing Guide to match this tank to your liquid's density and your equipment. The 1.9 SG rating means this tank is engineered for dense liquids well past water, which is why it shows up under searches for an Enduraplas horizontal leg tank rather than a light-duty water hauler.
Chemical compatibility
Our data lists the tank resin as HDLPE, but that value is unconfirmed in our records. Because the resin is unverified, treat the 1.9 SG rating and every chemical listing below as manufacturer chemical-resistance chart values pending confirmation - not as guaranteed for your specific service. Before you commit this tank to chemical use, confirm the exact resin (HDLPE versus XLPE) with us at 866-418-1777, because the resin determines both what it can safely hold and the density it can carry. The compatible chemicals below come from the manufacturer's chemical-resistance chart, which is concentration- and temperature-specific; always check your exact concentration and operating temperature against the OEM chart before filling. Note the fitting and gasket materials called out for each - the tank wall and the fittings are separate compatibility decisions.
Stainless-only constraint: three entries require 316 stainless steel rather than PVC or PP fittings - DEF (32.5%, 316SS, EPDM), Peracetic Acid (30%, 316SS, Aflas), and the PP/316SS pairings for Propylene Glycol and Zinc Orthophosphate. If you are hauling DEF, a standard PVC bulkhead kit will not work - plan on stainless fittings up front.
Compatible chemicals for this 1.9 SG tank include: Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS, EPDM), Ethylene Glycol (100%, PVC, EPDM), Ferric Chloride (50%, PVC, EPDM), Ferric Sulfate (60%, PVC, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Hydrochloric Acid (37%, PVC, Viton), Hydrofluoric Acid (48%, PP/PVC, Viton), Hydrofluosilicic Acid (26%, PP/PVC, Viton), Hydrogen Peroxide (50%, PVC, Viton), Magnesium Chloride (30%, PVC, EPDM), Peracetic Acid (30%, 316SS, Aflas), Phosphoric Acid (85%, PVC, Viton), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate (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 (30%, PVC, EPDM), Sodium Hypochlorite (<16.5%, PVC, Viton), Sodium Thiosulfate (40%, PVC, EPDM), Sulfuric Acid (98%, CPVC, Viton), Urea Solution (50%, PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). Ozonated Water is listed as compatible but does not yet have a dedicated reference page, so verify that one by phone. Confirm every selection on the OEM chemical-resistance chart and our chemical compatibility reference.
The mistake to avoid
The single most common error on a leg tank like this is filling a dense chemical without honoring both the 1.9 SG rating and the matching fitting material. The wall is rated for the load, but the fittings are not all the same - this tank calls out PVC, CPVC, PP, and 316SS, with gaskets ranging from EPDM to Viton to Aflas depending on the chemical. Sulfuric Acid at 98% needs CPVC and Viton; Peracetic Acid at 30% needs 316SS and Aflas; DEF needs 316SS. Mixing a Viton-class chemical into an EPDM-gasketed fitting is how a tank that "passed" the wall check still fails at the bulkhead. For DOT and fertilizer-haul use, review our guides on applicator and leg tanks for fertilizer, loaf-style portable utility tanks and the 49 CFR exemption, and fertilizer-blend tank stratification. Confirm dimensions and fitting locations against the technical drawing on this page before you build your trailer or skid.
