The Snyder Industries 525 Gallon Plastic Horizontal Leg Tank is a polyethylene haul tank built for transport and nurse-rig duty, rated to a 1.9 specific gravity so it can carry dense agricultural and industrial liquids that would overstress a lighter 1.0 to 1.5 SG tank. It measures 53 in high, 48 in wide, and 75 in long, riding on molded legs that let the full load settle low and stable on a trailer or skid. Buyers searching for a horizontal leg tank or Snyder horizontal tank in this size are usually moving water, fertilizer blends, or treatment chemicals between a fill point and the field, and this tank is sized for exactly that.
Will it work for your load?
Run the weight math before you mount it. Filled with water this 525-gallon body carries about 4,378 lb, and at its full 1.9 SG rating it can hold up to roughly 8,319 lb of contents. Your trailer, hitch, and tie-downs have to handle that loaded number, not the dry tank weight. A horizontal leg tank this long carrying a heavy partial load shifts weight under braking and acceleration, so plan hauling speeds and secure strapping across the full 48 x 75 in footprint and the 75-in long axis. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the rated capacity matches the volume and density you actually move, and check the technical drawing on this page for fitting and leg locations before you fabricate a cradle.
Chemical compatibility
This tank is rated to a 1.9 specific gravity. The resin code in our records is unconfirmed, so confirm the exact resin (HDLPE versus XLPE) with us before committing this tank to chemical service, since resin type affects compatibility with certain oxidizers and solvents. The chemicals below are drawn from the OEM chemical-resistance chart and are concentration- and temperature-specific, so always match your exact strength and service temperature against that chart before ordering.
Compatible services at the listed concentrations include 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), 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 (<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). The fitting and gasket material changes by chemical, for example Viton over EPDM on the acids and hypochlorite, and 316SS on DEF and peracetic acid, so spec the gasket and fitting body to the chemical, not just the tank. Polyaluminum chloride, propylene glycol, sodium bisulfate, sodium bisulfite, and zinc orthophosphate have no listed concentration in our chart, so confirm your strength with us rather than assuming any concentration is covered. See the full chemical compatibility reference and the OEM chart for concentration and temperature limits.
The mistake to avoid
The costly error on a haul tank like this is matching it to capacity alone and ignoring the 1.9 SG rating, the loaded weight, and the wetted-material requirements. A tank rated for a lighter liquid that gets filled with a heavy fertilizer blend or a dense treatment chemical can fail at the legs or fittings, and a sloshing fertilizer load can stratify in transit. Watch the wetted parts too: DEF, for instance, calls for 316SS fittings rather than the common PVC, so a hauler who specs PVC on a DEF load risks corrosion and contamination. If you are hauling blends, read fertilizer-blend tank stratification and the applicator and leg tank guide for DOT and non-roadable-trailer scope, plus the Snyder Captor double-wall SPCC walkthrough if your chemical needs secondary containment.
