The Snyder Industries 300 Gallon Plastic Horizontal Leg Tank is a transport-and-haul tank built for moving liquid loads where a tank cannot stand upright. The molded saddle legs hold the cylindrical body steady on a trailer, skid, or truck bed, and at 300 gallons it carries enough volume for field fertilizer runs, water hauling, and chemical transfer without tipping the balance of a small rig. Molded in white polyethylene, this horizontal leg tank measures 68 inches long, 38 inches wide, and 44 inches high, giving a 38.0 x 68.0 inch footprint that drops into most utility-trailer decks. Snyder rates this tank to a 1.9 specific gravity, which is what lets it haul dense chemicals and concentrated solutions, not just water.
Will it work for your load?
Filled with water, this 300 gallon tank carries roughly 2,502 pounds. Because it is rated to 1.9 specific gravity, the maximum rated contents weight climbs to about 4,754 pounds with a heavy liquid - so plan your trailer, axle, and tie-down capacity around the loaded number, not the dry tank. That 1.9 rating is the headroom that separates a true haul tank from a water-only barrel. Confirm fitting and outlet placement against the technical drawing on this page before you plumb a transfer pump or gravity outlet, and use our Tank Sizing Calculator and Tank Sizing Guide to match volume and weight to your application. If you are hauling fertilizer or running a non-roadable applicator rig, our guides on applicator and leg tanks for fertilizer and loaf-style portable utility tanks and 49 CFR 173.5 walk through the DOT classification questions that come up with on-farm fleet use.
Chemical compatibility
This tank is molded in high-density linear polyethylene with a 1.9 specific gravity rating. The resin code carries a question mark in our data, so confirm HDLPE versus XLPE construction with us before committing the tank to chemical service - it changes which aggressive chemicals the wall can hold. The compatibilities below are concentration-specific and pulled from the OEM chemical-resistance chart; always match your exact concentration and service temperature before ordering, and call us at 866-418-1777 if your chemical is not listed. Because this is a leg and haul tank, it is a natural fit for the fluid-transport side of an applicator program: it handles DEF at 32.5% on 316 stainless fittings with EPDM gaskets and urea solution at 50% on PP/PVC fittings with EPDM gaskets, the same nitrogen-based fluids that move through fertilizer applicator rigs.
With the right plumbing, this tank suits a broad range of salts, glycols, and mild acids: acetic acid at 60% (PP/PVC fittings, EPDM gaskets), aluminum sulfate at 50%, calcium chloride at 40%, ethylene glycol at 100%, ferric chloride at 50%, ferric sulfate at 60%, ferrous sulfate at 20%, and magnesium chloride at 30% - all on PVC fittings with EPDM gaskets unless noted. Salts and bases such as potassium carbonate at 50%, potassium hydroxide (saturated), sodium carbonate at 30%, and sodium thiosulfate at 40% run on PVC with EPDM. A handful of compatible chemicals are not concentration-rated in our data - polyaluminum chloride, sodium bisulfate, sodium bisulfite, zinc orthophosphate (PP/316SS fittings, EPDM), and propylene glycol (PP/316SS fittings, EPDM) - so confirm your exact strength with us before ordering for those.
Aggressive acids and oxidizers demand harder fittings and Viton or specialty gaskets, and the right pair matters more than anything else on the tank: hydrochloric acid at 37% (PVC fittings, Viton gaskets), hydrofluoric acid at 48% (PP/PVC fittings, Viton), hydrofluosilicic acid at 26% (PP/PVC fittings, Viton), hydrogen peroxide at 50% (PVC fittings, Viton), phosphoric acid at 85% (PVC fittings, Viton), sodium hypochlorite below 16.5% (PVC fittings, Viton), peracetic acid at 30% (316SS fittings, Aflas gaskets), and sulfuric acid at 98% (CPVC fittings, Viton). Ozonated water up to 10 PPM runs on PVC fittings with EPDM gaskets (call to confirm - no dedicated page yet). See each chemical's page and our chemical compatibility guide for the full concentration and temperature limits.
The mistake to avoid
The single most common error with a haul tank is loading a dense chemical without checking the specific gravity math. Water weighs about 8.34 pounds per gallon, but a concentrated brine or acid runs far heavier - that is exactly why this tank carries a 1.9 SG rating and a max rated contents weight near 4,754 pounds. Fill it with a heavy liquid and ignore the loaded weight and you will overload your trailer or axle long before the tank itself gives out. Pair that with the wrong fitting or gasket material on an aggressive acid and you trade a slow leak for a fast failure. Match the SG, match the fitting and gasket to the compatibility data above, and confirm everything against the technical drawing on this page first.
