The Snyder Industries 225 Gallon Horizontal Leg Tank is a 1.9 specific-gravity, white High Density Linear Polyethylene tank built for hauling heavy ag and water-treatment liquids on a transport skid or applicator frame. With a 38-inch by 52-inch footprint and a 42-inch overall height, it holds 225 gallons inside the molded leg structure that keeps the tank stable when full and in transit. The 1.9 SG rating is the figure that matters most: it means this tank is rated to carry contents up to 1.9 times the density of water, which is why this horizontal leg tank shows up under searches for a Snyder horizontal tank for fertilizer and chemical transport rather than only light-duty water storage. For DEF, 50% urea, or other near-water-density loads, that same rating is simply headroom you will not have to think about.
Will it work for your liquid and your trailer?
Full of water this tank weighs about 1,876 lb, and at its full 1.9 SG rating it can carry up to roughly 3,565 lb of contents. Use both numbers when you size the trailer, axle, and tie-downs: water tells you the floor load for fresh-water or low-density work, and the 3,565 lb max-contents figure is the ceiling you plan against for dense fertilizer blends or heavy treatment chemistry. When you set it on the deck, the 52-inch dimension is the length that runs front-to-back along the trailer and the 38-inch dimension is the width across the deck, so plan tie-down spacing and clearance to that orientation rather than mounting it sideways; the 42-inch height keeps it sitting low and centered on most applicator and utility trailers. Run those weights through the Tank Sizing Calculator, and if you are matching tank capacity to a fill rate or batch, the Tank Sizing Guide walks through the math. For the heavier ag-transport context, the guide to applicator and leg tanks for fertilizer covers DOT non-roadable trailer scope, and the portable utility tank classification guide explains the 49 CFR 173.5 agricultural exemption for farm-fleet use. See the technical drawing on this page for fitting locations and outlet positions before you plumb it.
Chemical compatibility
This is an HDLPE tank rated to 1.9 specific gravity, which is the maximum-density rating in the Snyder leg-tank family, so a wide range of concentrated ag and water-treatment chemistry is within reach when the fittings and gaskets are matched correctly, and there is no heavier-duty step-up to chase. Compatibility is always concentration- and temperature-specific, so confirm your exact conditions against the OEM chemical-resistance chart before service. A critical detail: the elastomer is not one-size-fits-all. The oxidizers and strong acids need Viton rather than EPDM, DEF and peracetic acid call for 316SS fittings, and 98% sulfuric acid needs CPVC rather than PVC.

The mistake to avoid
The error that ruins horizontal leg tanks is matching the tank to the liquid but ignoring the gasket and fitting material, and then under-rating the trailer. Treat both as one decision: spec the whole system to 1.9 SG. That means planning your tie-downs and trailer rating against the 3,565 lb max-contents weight rather than the lighter 1,876 lb water figure, and matching the elastomer to the chemical above — Viton (not EPDM) for the strong acids and oxidizers such as hydrochloric, phosphoric, hydrogen peroxide, and sodium hypochlorite; 316SS for DEF at 32.5% and peracetic acid; and CPVC (not PVC) for sulfuric acid at 98%. The 3,565 lb ceiling only holds if the fittings and gaskets you chose actually resist the chemical you are hauling, so confirm concentration and temperature against the OEM chart for every line.
