The Snyder Industries 3400 Gallon Plastic Horizontal Leg Tank is built to ride a trailer or truck bed, with molded legs and securing hoops that band it down to its mounting frame. It measures 155 inches long by 82 inches wide by 88 inches high, giving an 82.0 x 155.0-inch footprint, and is molded in white polyethylene rated to a 1.5 specific gravity. That SG rating is the number that decides what you can safely haul, so read the next section before you load anything heavier than water.
Will this horizontal leg tank work for your load?
This is a horizontal tank: the body sits low in its cradle legs so the full weight rides under the trailer deck while you move down the road. At 3400 gallons, plan your axle ratings around weight, not gallons. Full of water this tank carries 28,356 lb of contents; at its maximum 1.5 SG rating it holds 42,534 lb of contents, and the trailer and empty tank weight add on top of that. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm your fill volume and total rolling weight before you spec a chassis. The securing hoops earn their keep on a moving load: a partially filled horizontal tank surges, so band it down tight every trip. The pack lists no inlet, outlet, vent, or fitting schedule for this unit, so do not assume port sizes or locations from gallons alone, confirm every fitting against the technical drawing on this page before you plumb it.
Chemical compatibility
This tank is molded polyethylene rated to 1.5 specific gravity. The resin is recorded as HDLPE but is not fully confirmed, so verify HDLPE versus XLPE and the exact chemical service rating with the OEM before putting the tank into chemical service. Always check the OEM chemical-resistance chart, which is concentration- and temperature-specific, and match your fittings and gaskets to the chemical.
For an agricultural haul tank this size, the two highest-value loads on the compatible list are the ones it gets used for most: DEF at 32.5% (316SS fittings, EPDM gaskets) and urea solution at 50% (PP/PVC, EPDM) both sit well inside this 1.5 SG shell. Other products this tank can carry include acetic acid at 60% (PP/PVC, EPDM), aluminum sulfate at 50% (PVC, EPDM), calcium chloride at 40% (PVC, EPDM), ferrous sulfate at 20% (PVC, EPDM), magnesium chloride at 30% (PVC, EPDM), and sodium carbonate at 30% (PVC, EPDM). Also recorded compatible: ozonated water up to 10 PPM (PVC fittings, EPDM gaskets). Confirm every fitting and gasket material against the chart before plumbing.
What needs a higher-SG tank instead
Some products are heavier than this 1.5 SG shell should carry and need a 1.9 specific-gravity tank instead. If your load is 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, or zinc orthophosphate, step up to the higher-SG tank rather than overloading this one. The wetted-material call matters as much as the SG rating: hydrochloric acid, hydrofluoric acid, hydrofluosilicic acid, hydrogen peroxide, phosphoric acid, sodium hypochlorite, and sulfuric acid all call for Viton gaskets; peracetic acid calls for Aflas; sulfuric acid wants CPVC fittings; and peracetic acid and zinc orthophosphate want 316SS. Confirm both the tank rating and the wetted materials on the chemical compatibility chart before ordering. If you are hauling or storing these single-wall and fall under containment rules, our Snyder Captor double-wall tanks for SPCC 40 CFR 112 walkthrough covers the secondary-containment path.
The mistake to avoid
The single most common error on a horizontal leg tank is loading to gallons instead of to weight. This shell is rated to 1.5 SG; haul a 1.9-density product in it and you exceed the wall rating even when the tank is not full. Match the product to the SG rating first, then to fitting and gasket material, then size your axles to the 42,534 lb maximum rated contents weight. Because the pack lists no fitting schedule for this unit, treat the technical drawing on this page as the source for port locations and dimensions before you plumb it.
