The Snyder Industries 3400 Gallon Plastic Horizontal Leg Tank is a haul-and-store workhorse for liquid fertilizer, DEF, urea, and ag chemical transport where the load rides low and the integrated securing hoops and legs carry the weight. Molded in white polyethylene with a 1.5 specific gravity rating, it is built to hold liquids up to 1.5 times the weight of water at full volume. Footprint is 82.0 x 155.0 inches, with an overall height of 88 inches and a width of 82 inches across the 155-inch length. If you are spec'ing this horizontal leg tank for a nurse trailer or applicator skid, the dimensions and weights below are the numbers your frame and axle rating have to clear.
Will it work for your load?
Filled with water, this tank weighs 28,356 lb. At its 1.5 specific gravity rating it is built to carry up to 42,534 lb of contents at full capacity. Those two numbers matter more than gallons when you are matching the tank to a trailer or saddle: water gives you the baseline, and the max rated contents weight gives you the ceiling for heavier fertilizer blends. Run your intended fill level and product density through the Tank Sizing Calculator and the Tank Sizing Guide before you commit a chassis, and remember that a partly filled horizontal tank can stratify and shift load, real concerns covered in our guide to fertilizer-blend tank stratification. For the regulatory side of hauling fertilizer on a non-roadable or farm trailer, see our walkthroughs on applicator and leg tanks for fertilizer and the 49 CFR agricultural exemption. One caution before you buy valves: fitting size and configuration are not specified in our catalog data for this SKU, so confirm outlet size and bulkhead or manway layout from the technical drawing on this page or with us before you order plumbing.
Chemical compatibility
This tank is molded polyethylene rated to 1.5 specific gravity. The resin is recorded as HDLPE in our data but ends with a question mark, meaning it is unconfirmed; that is fine for water and routine ag use, but for any chemical service you must verify the resin with us by phone first, because a compatibility table assumes a known resin and an unverified one invalidates it for aggressive chemistries. At the 1.5 SG rating, this tank suits Acetic Acid at 60%, Aluminum Sulfate at 50%, Calcium Chloride at 40%, DEF at 32.5% (the diesel exhaust fluid spec), Ferrous Sulfate at 20%, Magnesium Chloride at 30%, Sodium Carbonate at 30%, Urea Solution at 50%, and Ozonated Water up to 10 PPM. Fitting and gasket materials are chemical-specific: most call for PVC fittings with EPDM gaskets, Acetic Acid and Urea Solution use PP or PVC fittings, and DEF requires 316 stainless steel fittings, all per the OEM chemical-resistance chart, which is concentration- and temperature-specific. Verify your exact concentration and operating temperature against that chart and our chemical compatibility resource. Detail pages: Acetic Acid, Aluminum Sulfate, Calcium Chloride, DEF, Ferrous Sulfate, Magnesium Chloride, Sodium Carbonate, and Urea Solution.
Chemicals that need a higher-SG tank
Some products exceed what a 1.5 SG tank should hold and require a 1.9 specific gravity tank instead. If your service is Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrochloric Acid, Hydrofluoric Acid, Hydrofluosilicic Acid, Hydrogen Peroxide, Peracetic Acid, Phosphoric Acid, Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Hypochlorite, Sodium Thiosulfate, Sulfuric Acid, or Zinc Orthophosphate, do not run it in this 1.5 SG tank. Fitting metallurgy tightens at this level too: Sulfuric Acid calls for CPVC fittings, Peracetic Acid needs 316 stainless steel fittings with Aflas gaskets, and Hydrochloric, Hydrofluoric, Phosphoric, Hydrogen Peroxide, and Sodium Hypochlorite all use Viton gaskets rather than EPDM, so match the gasket and fitting to the chemical on the OEM chart.
This horizontal leg tank ships LTL freight from the Snyder Industries plant in Lincoln, NE, with the cost quoted live to your delivery ZIP. Get your number on the Freight Cost Estimator or call 866-418-1777 to talk through fitting layout and the right specific-gravity rating for your chemical. If your service falls in the higher-SG list above, the 1.9 SG version is a separate SKU, call us and we will match the exact 1.9 SG horizontal leg tank and the correct gasket (Viton or Aflas instead of EPDM) for your chemistry and delivery for your nurse trailer or applicator build.
