The Snyder Industries 525 gallon horizontal leg tank is a haul-built workhorse for moving bulk liquid by trailer, applicator, or nurse rig. Molded in high density linear polyethylene with a 1.5 specific gravity rating, this Snyder horizontal tank holds 525 gallons, measures 71 inches long by 49 inches wide by 56 inches tall, and sits on a flat leg footprint of 49 by 71 inches so it loads square on a skid or trailer deck. Fitting locations, outlet geometry, and overall dimensions are shown on the technical drawing on this page.
Will it work for your load?
Capacity is the easy part; weight is what dictates your trailer and your axle math. Filled with plain water this tank carries roughly 4,378 lb of contents, and at its full 1.5 SG rating it is engineered to support up to 6,568 lb of liquid weight. Run those numbers against your trailer rating, your tongue weight, and your road plan before you fill, and use the Tank Sizing Calculator and Tank Sizing Guide to confirm the size matches your application. The 1.5 SG rating is the line that keeps you out of trouble: a horizontal leg tank that handles 525 gallons of water will not necessarily handle 525 gallons of a denser fluid, so always size to the density of what you are actually hauling, not to gallons alone.
Chemical compatibility
This tank is HDLPE rated to 1.5 specific gravity. At that rating it pairs with the solutions below per the OEM chemical-resistance chart, which is concentration and temperature specific - verify your exact conditions against it before committing. One point that catches people: the polyethylene wall is what handles the chemical, but the fitting and gasket materials listed are the interface you must match at every penetration - that connection fails before the wall does, so match it exactly. Worth calling out for fleet buyers is DEF (diesel exhaust fluid) at 32.5 percent, which is compatible here but requires 316 stainless fittings rather than PVC.
- Acetic Acid (60%) - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate (50%) - PVC fittings, EPDM gaskets
- Calcium Chloride (40%) - PVC fittings, EPDM gaskets
- DEF (32.5%) - 316SS fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
Several common chemicals are NOT a fit for this 1.5 SG tank and need a higher 1.9 SG tank instead - this includes 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. If you are hauling any of those, we can source the 1.9 SG equivalent for you rather than running them in this tank - call 866-418-1777 and we will spec it. Always confirm against the full chemical compatibility reference before you fill.
The mistake to avoid
The most common error on a horizontal leg tank is matching gallons to the trailer and ignoring density. This is a 1.5 SG tank: running a heavier fluid past that rating, or specifying EPDM where the chart calls for Viton or Aflas on an aggressive chemical, is how leg tanks fail in the field. Read the gasket and fitting material column for your specific chemical and match it exactly.
