The Snyder Industries 500 Gallon Plastic Vertical Chemical Storage Tank gives chemical operators a high-density polyethylene vessel rated to 1.9 specific gravity, which is what separates it from a general-purpose water tank. At 73 inches tall on a 48 x 48 inch footprint, this white vertical storage tank holds 500 gallons and is built for heavier-than-water solutions where a standard 1.0 to 1.5 SG tank would be under-spec.
Will it work for your application
Start with weight. Filled with water, the contents weigh about 4,170 lb, but this 500 gallon tank carries a maximum rated contents weight of 7,923 lb at its 1.9 SG rating. That headroom is the whole point of a chemical-grade vessel: it lets you store dense liquids like concentrated acids and salt brines without exceeding the wall design. The 48 x 48 inch footprint and 73 inch height let you plan pad space, doorway clearance, and headroom before delivery. Worth knowing: the same 500 gallon, 48 inch diameter vertical tank also comes in a shorter 68 inch stack, so if doorway or ceiling clearance is tight you can trade height for the same volume - compare the two in our 48 x 73 buyer's guide versus the 48 x 68 version. Use the Tank Sizing Calculator and our Tank Sizing Guide to match this vertical storage tank to your draw-down and refill cycle, and see the technical drawing on this page for fitting locations and detailed dimensions.
Chemical compatibility
This is a polyethylene tank with a 1.9 specific gravity rating. The exact resin grade is not confirmed in our data - confirm high-density linear polyethylene (HDLPE) versus crosslinked (XLPE) with us at 866-418-1777 before committing to chemical service, since the resin choice materially changes long-term resistance for oxidizers and strong acids. Note that fittings and gaskets are not included with the bare tank: they are selected and supplied separately to match your confirmed chemical, concentration, and temperature. The compatibility data below is concentration- and temperature-specific, so verify your exact conditions against the manufacturer compatibility data and our Chemical Compatibility Database before ordering.
At the listed concentrations, this tank suits a wide range of service. With PVC fittings and EPDM gaskets it handles Aluminum Sulfate (50%), Calcium Chloride (40%), Ethylene Glycol (100%), Ferric Chloride (50%), Ferric Sulfate (60%), Ferrous Sulfate (20%), Magnesium Chloride (30%), Potassium Carbonate (50%), Potassium Hydroxide (saturated), Sodium Carbonate (30%), Sodium Thiosulfate (40%), and Polyaluminum Chloride. Acetic Acid (60%) and Urea Solution (50%) use PP or PVC fittings with EPDM. A common high-intent use is DEF (diesel exhaust fluid, 32.5%), which calls for 316 stainless fittings with EPDM gaskets. Oxidizers and strong acids step up to Viton: Hydrochloric Acid (37%), Hydrogen Peroxide (50%), Phosphoric Acid (85%), Sodium Hypochlorite (under 16.5%), and with CPVC fittings, Sulfuric Acid (98%). Hydrofluoric Acid (48%) and Hydrofluosilicic Acid (26%) run PP/PVC fittings with Viton, and Peracetic Acid (30%) needs 316SS fittings with Aflas gaskets. Sodium Bisulfate and Sodium Bisulfite use PVC or PP with EPDM; Propylene Glycol and Zinc Orthophosphate use PP or 316SS with EPDM. Ozonated Water (up to 10 PPM) runs PVC fittings with EPDM gaskets.
The mistake to avoid
Do not confuse the gasket and fitting material with the tank itself. The polyethylene shell handles the chemical; the fitting and gasket at the bulkhead are where service most often fails. Sodium hypochlorite, sulfuric, phosphoric, hydrochloric, hydrofluoric, hydrogen peroxide, and peracetic acid all demand Viton, Aflas, or 316SS hardware - install EPDM there and the connection degrades even though the tank is fine. The other common error is under-rating: this 1.9 SG tank exists so you do not load a dense liquid into a 1.0 SG water tank, and 1.9 is the heavy-duty top rating in this line. If you are metering or batching, size your level instrumentation deliberately - our guide on tank level gauge selection for chemical service walks through radar, ultrasonic, hydrostatic, and magnetostrictive options, and for the filled tank our guide on NFPA 704 and GHS signage compliance covers labeling.
