The Enduraplas 800 Gallon Green Horizontal Leg Tank (SKU THF00800G) is a polyethylene horizontal leg tank built for hauling and field transfer where the load has to ride low and stay put. It carries 800 gallons in a tank that measures 94 inches long, 60 inches wide, and 48 inches tall, with a 60 x 94 in footprint that spreads the weight across the integrated legs. The tank is green, and the polyethylene wall carries a 1.9 specific gravity rating, which is what lets this horizontal leg tank handle heavy chemicals and fertilizer blends rather than water alone.
Will it work for your load
Sizing is where horizontal leg tanks catch people off guard, so run the real numbers before you spec a trailer or skid. Filled with water this tank weighs about 6,672 pounds. At its full 1.9 SG rating the maximum rated contents weight climbs to 12,677 pounds, so the frame, axles, and tie-downs under it have to be rated for the densest product you plan to move, not for water. This tank ships without chemical fittings installed, so select your fitting and gasket material from the table below to match your product and confirm sizing at order. Use the Tank Sizing Calculator and the Tank Sizing Guide to match this 800-gallon capacity and footprint to your transport setup.
Chemical compatibility
Confirm before chemical service: the polyethylene resin grade on this tank should be verified (HDLPE versus XLPE) before any chemical duty, because cross-linked and linear polyethylene behave differently with aggressive products. Call 866-418-1777 to confirm the resin grade before you order this tank for chemical service. The 1.9 SG rating means you can fill it with dense chemistry up to that gravity; at a 1.9 specific-gravity rating this tank is already specified for the densest products in the compatibility list, so there is no higher-gravity poly tank to step up to. Compatibility below is drawn from the OEM chemical-resistance chart and is concentration- and temperature-specific, so verify your exact concentration and operating temperature against that chart before filling.
Confirmed compatible products and the fitting and gasket materials they call for include Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS fittings, 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 (under 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). Match the gasket to the chemical, not the other way around, and never reuse Viton-spec fittings on an EPDM product or the reverse. Note that DEF and peracetic acid in particular cannot run on standard PVC/EPDM hardware - DEF needs 316SS and peracetic acid needs 316SS with Aflas gaskets. For the full matrix and to plan a multi-product program, see our chemical compatibility reference.
The mistake to avoid
The costly error on a 1.9-SG tank is spec'ing the trailer or skid for water weight. People see 6,672 pounds full of water and build to that, then the tank fails under 12,677 pounds of a dense chemical or a salted-out fertilizer blend. If you are running fertilizer, read up on fertilizer-blend tank stratification so density-driven layering does not throw your spreader off-spec, and review the DOT classification rules in our applicator and leg tanks for fertilizer and portable utility tank guides before you take a full leg tank on the road.
