The Snyder Industries 1025 Gallon Plastic Horizontal Leg Tank (SII-32042) is a white, high-density linear polyethylene horizontal leg tank built for hauling and applicator work where a wide, low-slung tank rides a trailer or skid through the field. It measures 139 inches long by 48 inches wide by 55 inches tall, and the molded legs give it the flat footprint that keeps a full horizontal tank stable in transit. The 1.5 specific gravity rating means it is built to carry heavier-than-water liquids, not just fresh water - which is what makes it a workhorse for fertilizer blends, ag chemicals, and DEF.
Will it work for your liquid?
Capacity is 1025 gallons. Full of water that is roughly 8,548 pounds; at the full 1.5 specific gravity rating the tank holds up to 12,823 pounds of contents - a 4,275-pound swing between a water load and a heavy fertilizer or brine load. Treat that 12,823-pound number as your go/no-go check: size the trailer cross-members, skid, or pad for the rated weight, not the water weight, because that delta is exactly what cracks an under-built support structure on a 139-inch horizontal leg tank. Run your liquid through the Tank Sizing Calculator and the Tank Sizing Guide to confirm the gallons and the loaded weight match your equipment before you commit it.
Chemical compatibility
This is an HDLPE tank with a 1.5 specific gravity rating. Compatibility is concentration-, fitting-, and gasket-specific, so match every component to your actual service - and remember the gasket is the weak link: the right tank with the wrong gasket is still a compatibility failure. Within the 1.5 SG rating, this tank is suitable for the following at the noted concentrations: Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS fittings, EPDM gaskets), Ferrous Sulfate (20%, PVC, EPDM), Magnesium Chloride (30%, PVC, EPDM), Sodium Carbonate (30%, PVC, EPDM), Urea Solution (50%, PP/PVC, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). Note that DEF calls for 316SS fittings, and Ozonated Water is the one compatible chemical here without its own dedicated reference page yet - verify it directly against the OEM chemical-resistance chart. Always confirm your chemical, concentration, and temperature on our full Chemical Compatibility reference before ordering.
The mistake to avoid: matching the SG and the gasket
A 1.5 SG tank does not cover everything. A long list of common ag and water-treatment chemicals need a higher 1.9 specific gravity tank and must NOT be run in this one - if your liquid is on this list, step up to a 1.9-SG-rated tank rather than forcing it into this one: 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, and Zinc Orthophosphate. The second trap is the gasket: several of these require Viton (Sulfuric Acid, Hydrochloric Acid, Hydrogen Peroxide, Sodium Hypochlorite, Phosphoric Acid, Hydrofluoric Acid, Hydrofluosilicic Acid) or Aflas (Peracetic Acid) rather than EPDM. Match the fitting material - PP, PVC, CPVC, or 316SS - AND the gasket to the specific chemical; reusing an EPDM kit on a Viton-required service fails even with the correct tank.
Fittings and field setup
Match your fitting and gasket materials to the chemical you intend to run, and consult the technical drawing on this page for the tank's dimensions and layout. If you are blending or hauling fertilizer, our guides on applicator and leg tanks for fertilizer, fertilizer-blend tank stratification, and portable utility tank DOT classification walk through field setup; for secondary containment, see Snyder Captor double-wall tanks for SPCC.
Freight
This horizontal leg tank ships LTL from the nearest of two Snyder Industries plants - Albertville, AL and Merced, CA - with freight quoted live to your ZIP. On a 139-inch oversize tank, origin distance drives the cost, and the dual-plant footprint is the advantage: buyers west of the Rockies route from Merced, eastern and southern buyers from Albertville, so the quote runs from the closer plant. Get your number on the Freight Cost Estimator, or call 866-418-1777 and we will route it from the nearest plant and confirm gallons, weight, and fittings for your application before it ships.
