The Snyder Industries 730 Gallon Horizontal Leg Tank (SKU SII-1360000N45) is a white, high density linear polyethylene tank built to ride in a cradle or skid frame and haul liquid down the road. It holds 730 gallons, measures 80 inches long by 54 inches wide by 58 inches tall, and rests on integrally molded legs that give it a flat, stable 54.0 x 80.0 inch footprint. Watch the weight gap before anything else: filled with plain water it sits near 6,088 pounds, but loaded to its 1.9 specific gravity ceiling it can carry roughly 11,568 pounds of contents. Size your trailer and tie-downs for the heavier number, not the water number. That 1.9 rating is high for a leg tank and is what lets this unit haul dense agricultural and industrial liquids that would over-stress a lighter-rated tank.
Will it work for your load?
Sizing a horizontal leg tank is a weight exercise, not just a gallon exercise. The 1.9 rating is the ceiling, so check your liquid's specific gravity against a full fill: a 1.6 SG liquid at full volume lands near 9,740 pounds, still inside rating, while water (1.0 SG) only reaches about 6,088 pounds. Run your numbers through the Tank Sizing Calculator and Tank Sizing Guide before you commit, and refer to the technical drawing on this page for fitting locations and leg spacing before you build your mount. As a horizontal hauling and nurse-tank workhorse, this is the kind of leg tank that pairs with a trailer for transport rather than stationary storage. Because Snyder molds it at three plants, it ships from whichever of Chowchilla, CA, Lincoln, NE, or Philippi, WV is closest to your ZIP, which keeps LTL miles down on a tank this size.
Chemical compatibility
This shell is HDLPE rated to 1.9 specific gravity, which makes it a candidate for many dense chemical solutions, not just water. The resin grade is confirmed HDLPE here, but always match the fitting and gasket materials to the chemical and verify against the OEM chemical-resistance chart, which is concentration- and temperature-specific. Most listed chemicals run on PVC fittings with EPDM gaskets; the exceptions that demand upgraded hardware are Sulfuric Acid at 98% (CPVC fittings, Viton gaskets) and Peracetic Acid at 30% (316 stainless, Aflas), plus the Viton-gasket acids below. Budget for those materials rather than assuming standard PVC. The chemicals compatible with this tank when fitted correctly are: Acetic Acid at 60% (PP/PVC, EPDM), 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 below 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). See our full chemical compatibility resource for the detail behind each pairing.
The mistake to avoid
The error that wrecks a leg tank like this is loading a heavy chemical without confirming the specific gravity rating covers it. This shell carries a 1.9 rating, but that is the top of the practical leg-tank class, not a guarantee for every fluid, and there is no higher-rated drop-in replacement in this horizontal format. Buyers cross-shop leg tanks rated only to 1.5 and assume they are interchangeable; they are not. Confirm your chemical's actual specific gravity sits under 1.9, then match the fitting material and gasket compound exactly to the OEM chart, because the right hardware matters as much as the tank for an aggressive chemical such as Sulfuric Acid, which calls for CPVC. For background on transport-rated tanks, our guides on the applicator and leg tanks for fertilizer and fertilizer-blend tank stratification are worth reading.
