The Snyder Industries 3600 Gallon Cone Bottom Tank (SKU 8050000N43) is built for full-drain chemical handling where you cannot leave residue sitting on a flat floor. Molded in natural white polyethylene with a 1.5 specific gravity rating, this cone tank stands 125 inches tall on a 102 x 102 inch footprint and holds 3,600 gallons. The cone geometry self-empties to the bottom outlet, which makes it a working choice for batching, blending, and dosing where clean changeover matters. It requires a matching steel or fiberglass support stand to carry the load on the cone, and fittings are not included - they must be specified by chemical and SG service, so confirm your bulkhead and outlet configuration at order.
Will this tank work for your application?
The number that governs everything here is the 1.5 specific gravity rating. At 3,600 gallons of plain water you are already carrying 30,024 pounds, and the tank is rated to a maximum contents weight of 45,036 pounds on a 102 x 102 inch footprint. That ceiling is the real limit, and the math is worth doing before you fill: at 1.5 SG the tank hits 45,036 lb at exactly 3,600 gallons (30,024 x 1.5 = 45,036), so 1.5 is the densest fluid that fills all the way to full volume. A heavier fluid runs out of weight before volume - a 1.9 SG liquid maxes at roughly 2,840 gallons before it reaches the limit, so you would not get the full capacity. Size the stand and foundation to the loaded weight, not the empty shell. If you are deciding between footprint and height, the Tank Sizing Calculator and Tank Sizing Guide will help you match contents weight to capacity.
Chemical compatibility
This is a polyethylene tank rated to 1.5 specific gravity. Before you commit it to chemical service, confirm the exact resin grade with us - the molded resin can read as HDLPE here, but HDLPE versus XLPE changes which chemicals it can safely hold, so verify it for your duty. Compatibility is always concentration- and temperature-specific, so check the OEM chemical-resistance chart for your exact service before ordering fittings or gaskets.
At the 1.5 SG rating, this tank suits the following at the listed concentrations, with the recommended fitting and gasket materials:
- Acetic Acid (60%) - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate (50%) - PVC fittings, EPDM gaskets
- Calcium Chloride (40%) - PVC fittings, EPDM gaskets
- DEF (32.5%) - 316SS fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
If you are in fluid blending or transport prep, note that DEF and urea solution are not the same fitting spec: DEF at 32.5% calls for 316SS - it is intolerant of most metals, so do not default it to PVC - while urea solution at 50% runs on PP or PVC. Both use EPDM gaskets. Several heavier chemicals are NOT a fit for this 1.5 SG tank and need a 1.9 SG-rated tank instead: 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, and Zinc Orthophosphate. If your service is on that list, you need a 1.9 SG-rated Snyder cone tank, not this one - call 866-418-1777 for the matching heavier model. Note the gasket changes for the aggressive oxidizers and acids in that group: sodium hypochlorite, hydrogen peroxide, phosphoric, hydrochloric, and hydrofluoric acids call for Viton; peracetic acid calls for Aflas; sulfuric acid runs on CPVC fittings with Viton - not the default EPDM.

The mistake to avoid
The most common error on a cone tank this size is matching the chemical to the resin while ignoring the specific gravity math. A 1.5 SG tank will physically hold a denser fluid, but it will exceed the 45,036 lb contents rating before the tank is full, which stresses the wall and the stand. Decide your fluid's SG first, then confirm both the chemical resistance and the weight against the 45,036 lb limit. The other recurring miss is gasket material: the same chemical can call for EPDM in one service and Viton in another, so spec the gasket to the chemical, not to whatever shipped on the fitting.
