The Snyder Industries 1685 Gallon Plastic Horizontal Leg Tank is a haul-built poly tank engineered to carry dense agricultural and industrial liquids down the road, not just store water in a yard. Molded in white polyethylene at a 1.9 specific gravity rating, it measures 159 inches long, 48 inches wide, and 62 inches tall, with integral securing hoops cast into the body so you can strap it to a trailer or skid without rigging a separate cradle. The full water weight runs 14,053 lb, and at the 1.9 SG rating the tank is rated to carry up to 26,701 lb of contents - the number that actually matters when you are hauling a heavy fertilizer blend or a concentrated acid.
Will this tank work for your job?
This is a horizontal leg tank built for transport. The white poly shell lets you eyeball liquid level, and the elongated 48-by-159-inch footprint keeps the load low and stable behind a tractor or truck. Use the full-water figure of 14,053 lb for plain water service; if you are filling with anything denser, size your trailer, axles, and tie-downs against the 26,701 lb maximum rated contents weight, not the water number. Run the numbers through our Tank Sizing Calculator, and if you are unsure how a horizontal leg tank fits your application, the Tank Sizing Guide walks through capacity, footprint, and weight planning. For DOT and trailer-scope questions on hauling fertilizer in a leg-style tank, see our guides on applicator and leg tanks for fertilizer and portable utility tanks under the agricultural exemption.

Chemical compatibility
This tank is molded in polyethylene with a 1.9 specific gravity rating - already the heavy-duty tier of the poly SG ladder, so no higher-SG substitution is needed for the chemistries listed below. Our resin record carries a question mark, so confirm the exact resin grade and whether this specific tank is linear or cross-linked polyethylene before committing it to chemical service - that distinction changes long-term resistance. The single most important takeaway: fitting and gasket material is chemical-specific, and the wrong elastomer fails long before the tank does. DEF and peracetic acid call for 316 stainless fittings; sulfuric acid at 98% needs CPVC; the harsh acids - hydrochloric, hydrofluoric, hydrofluosilicic, phosphoric, hydrogen peroxide, and sodium hypochlorite - require Viton gaskets rather than EPDM, and peracetic acid uniquely calls for Aflas. Every rating below comes from the OEM chemical-resistance reference and is concentration- and temperature-specific, so match your actual fluid and operating temperature before you trust it.
At the listed concentrations, this 1.9 SG poly is referenced for 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), Potassium Carbonate (50%, PVC, EPDM), Potassium Hydroxide (saturated, PVC, 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), and Ozonated Water (up to 10 PPM, PVC, EPDM). A further group is referenced without a concentration in our record - confirm strength before service: Polyaluminum Chloride (PVC, EPDM), Propylene Glycol (PP/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), and Zinc Orthophosphate (PP/316SS, EPDM). See the full chemical compatibility reference and match concentration and temperature before ordering.
Freight and ordering
This tank ships LTL freight from the Snyder plant in Lincoln, NE, quoted live to your ZIP code - an empty 1685-gallon horizontal tank is a large, light, low-density freight item, so the rate depends heavily on destination and accessorial needs like liftgate or limited-access delivery. Get an exact number with our Freight Cost Estimator, or call us at 866-418-1777 and we will work the quote with you. If you are spec'ing a double-wall option for SPCC containment instead, our walkthrough on Snyder Captor double-wall tanks for SPCC 40 CFR 112 and the guide on fertilizer-blend tank stratification are worth a read before you commit.
