The Snyder Industries 300 Gallon Plastic Horizontal Leg Tank is a 1.9 specific-gravity polyethylene haul tank built for moving liquid down the road on a trailer or skid. It carries 300 gallons in a white tank measuring 72 inches long, 38 inches wide, and 43 inches tall, with the molded support legs that let a horizontal leg tank sit flat and stable on a flatbed. The 1.9 SG rating is the top of the leg-tank range, which is what lets this tank haul dense agricultural and chemical liquids rather than water alone - and a popular form factor for everything from a 300 gallon DEF run to fertilizer transport.
Will it work for your job?
This is a horizontal leg tank sized for transport, so the first thing to plan around is loaded weight. Filled with water (SG 1.0), the contents alone weigh about 2,502 pounds. At its full 1.9 SG rating, the tank is engineered to carry up to 4,754 pounds of contents - that headroom is the whole point of the heavier wall. Confirm your trailer, hitch, and tie-down points are rated for the loaded figure before you run it. The 38 x 72 inch footprint tells you the deck space you need; check the legs against your trailer frame so the load sits evenly and the straps pull down over the molded tie-down geometry rather than across an unsupported span. If you are sizing this against other capacities or matching it to a pump and run cycle, the Tank Sizing Calculator and Tank Sizing Guide walk through the math.
Chemical compatibility
This is a polyethylene tank with a 1.9 specific-gravity rating. The resin is read as HDLPE but the grade is not fully confirmed in our data - before you put any chemical in this tank, confirm HDLPE versus XLPE (crosslinked) with us at 866-418-1777, because crosslinked polyethylene resists a different range of chemicals than linear, and that distinction changes the compatibility list below. The compatibilities here come from the OEM chemical-resistance chart and are specific to concentration and temperature - match your actual conditions before committing. A common use here is DEF / diesel exhaust fluid at 32.5% - just run it on 316SS fittings with EPDM gaskets, not PVC hardware.
Chemicals this tank handles at its rated SG, with the recommended fitting and gasket materials, include: acetic acid (60%, PP/PVC fittings, EPDM gaskets), aluminum sulfate (50%, PVC, EPDM), calcium chloride (40%, PVC, 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 (under 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). Note that the fitting and gasket material changes by chemical - the oxidizers and strong acids call for Viton or Aflas gaskets and CPVC or 316SS hardware, not the EPDM you would use for a salt solution. Full concentration and temperature detail lives on each chemical's page and on the chemical compatibility guide.
The mistake to avoid
Two traps on a haul tank like this. First, do not assume the 4,754 pound rating means you can fill it with anything - that number is the structural ceiling at 1.9 SG, which is the top of the leg-tank range. If your liquid is denser than 1.9 SG there is no heavier leg tank to step up to, so call 866-418-1777 about a different form factor rather than overloading this one; running it past 1.9 SG, or on a frame that is not rated for the load, is how leg tanks fail in transit. Second, do not reuse fittings or gaskets from a previous product. As the list above shows, switching from a salt solution to sodium hypochlorite or sulfuric acid means switching gasket and fitting material too. For agricultural transport context, our guides on applicator and leg tanks for fertilizer and fertilizer-blend tank stratification cover load and mixing detail; for the DOT side of portable utility hauling, see our writeup on portable utility tanks and the 49 CFR 173.5 farm exemption. See the technical drawing on this page for exact fitting locations and leg geometry.
This tank ships LTL freight from the nearest Snyder Industries plant - Lincoln, NE for central and western buyers, Philippi, WV for eastern - quoted live to your ZIP, so the two-plant footprint usually means a shorter, cheaper haul to your door.
