The Snyder Industries 1650 Gallon Heavy Duty Cone Bottom Tank is a full-drain vessel built for batched chemical service, molded in black High Density Linear Polyethylene and rated to a 1.9 specific gravity. Standing 94 inches tall on an 86 x 86 inch footprint, it holds 1,650 gallons and discharges completely through its coned bottom, which is why it carries fittings and a stand rather than sitting flat. The 1.9 SG rating is the headline number here: it means the wall thickness is sized to carry contents up to 1.9 times the weight of water, so this is a tank meant for dense, aggressive liquids, not just water storage.
Will it work for your application
This is a cone bottom tank (sometimes searched as a cone tank) that requires a matching stand to support the full load. Filled with water it weighs roughly 13,761 pounds; loaded to its maximum rated contents it carries up to 26,146 pounds, so the supporting stand and floor must be engineered for that figure, not the empty weight. From the factory the tank comes with a bottom FLANGE for full drainage, a 10-inch polyethylene threaded and vented lid, and a fill cap with a 7-inch access opening. The 7-inch fill-cap access governs what instrumentation or dip tubes you can drop in, while the 10-inch vented lid is the primary top entry. Confirm your plumbing and dispensing hardware match those connections before ordering, and see the technical drawing on this page for exact fitting placement and dimensions. For matching the stand to this size and family, the Cone Bottom Tank Stand Compatibility Matrix is the fastest reference, and the Tank Sizing Calculator and Tank Sizing Guide help confirm the 1,650-gallon size fits your throughput.
Chemical compatibility
This tank is molded in HDLPE and carries a 1.9 specific gravity rating, which covers a wide range of dense chemicals. Always check the OEM chemical-resistance chart for your specific concentration and operating temperature before committing to service, and match your fittings and gaskets to the chemical, not just the tank. Verified compatible chemicals at the listed concentrations include Acetic Acid (60%, PP/PVC fittings, EPDM gasket), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS fittings, EPDM gasket), 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 fittings, Viton gasket), Urea Solution (50%, PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). The gasket and fitting tier shifts with the chemical: EPDM gaskets cover the salts, glycols, and most bases by default; Viton handles the oxidizers and strong acids like sodium hypochlorite, hydrogen peroxide, sulfuric, phosphoric, hydrochloric, and hydrofluoric acid; and Aflas is called out specifically for peracetic acid. On the fitting side, watch the metal and chlorinated cases: 316 stainless for DEF, peracetic acid, propylene glycol, and zinc orthophosphate, and CPVC rather than PVC for 98% sulfuric acid.

The mistake to avoid
The most common error on a tank like this is treating the 1.9 SG rating as a blank check. The rating governs the weight the wall can carry, not chemical resistance, and it does not by itself certify the resin for a given chemical. Confirm your chemical against the OEM resistance chart at your real concentration and temperature, and select fittings and gaskets accordingly. A second mistake is undersizing the stand: a tank that drains to a point puts all of its loaded weight on the cone and its support structure, so the stand must be rated for the full contents weight of up to 26,146 pounds. For dense or hazardous service, also review the Snyder Captor Plus 110% containment comparison and the tank labeling and signage compliance guide so containment and hazard placarding are handled before the tank goes into service.
Configured with 316-stainless fittings and EPDM gaskets, this tank also suits DEF (32.5%) bulk storage. It ships LTL freight from the nearest Snyder plant, either Chowchilla, CA or Lincoln, NE, with the rate quoted live to your ZIP code through our Freight Cost Estimator.
