The Snyder Industries 4100 Gallon Heavy Duty Cone Bottom Tank (SKU 5180000N51) is built for full-drain bulk chemical storage and batch processing where you need every gallon to evacuate through the cone. It is molded from black high density linear polyethylene (HDLPE) and is rated to store liquids up to 1.9 specific gravity, so it handles dense chemistry that thins-walled water tanks cannot. At 197 inches tall on a 90 by 90 inch footprint, this is a tall cone tank that runs on a matching support stand, and it answers the question most buyers ask first: yes, it handles heavy chemistry, and it drains clean.
Specs and load planning
Capacity is 4100 gallons. Filled with water the contents weigh 34,194 lb; at the full 1.9 SG rating the maximum rated contents weight climbs to 64,969 lb (that figure reflects the 1.9 rating, not water). That spread matters when you size the stand and the slab, so run the numbers against your actual liquid before you pour concrete or order steel, and use the Tank Sizing Calculator and Tank Sizing Guide to confirm the cone tank geometry fits your batch volume and headroom. At 197 in (16.4 ft) tall before the stand adds any height, confirm overhead clearance and fill access before siting. Because the discharge is at the bottom of the cone, plan piping and valve clearance under the tank for the 90 by 90 inch footprint. Fittings are specified to your chemistry and ordered separately; none are pre-installed on the base tank.
Chemical compatibility
This tank is HDLPE rated to 1.9 SG. The fitting and gasket pairings below come from the OEM chemical-resistance chart and are concentration and temperature specific, so confirm your actual service conditions against that chart before ordering. With the right fitting and gasket, this tank suits batch blending of DEF at 32.5% (316SS, EPDM), Urea Solution at 50% (PP/PVC, EPDM), Ethylene Glycol at 100% (PVC, EPDM), and Propylene Glycol (PP/316SS, EPDM). The full compatible list also includes Acetic Acid at 60% (PP/PVC, EPDM), Aluminum Sulfate at 50% (PVC, EPDM), Calcium Chloride at 40% (PVC, EPDM), Ferric Chloride at 50% (PVC, EPDM), Ferric Sulfate at 60% (PVC, EPDM), Ferrous Sulfate at 20% (PVC, EPDM), Hydrochloric Acid at 37% (PVC, Viton), Hydrofluoric Acid at 48% (PP/PVC, Viton), Hydrofluosilicic Acid at 26% (PP/PVC, Viton), Hydrogen Peroxide at 50% (PVC, Viton), Magnesium Chloride at 30% (PVC, EPDM), Peracetic Acid at 30% (316SS, Aflas), Phosphoric Acid at 85% (PVC, Viton), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate at 50% (PVC, EPDM), Potassium Hydroxide saturated (PVC, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), Sodium Carbonate at 30% (PVC, EPDM), Sodium Hypochlorite below 16.5% (PVC, Viton), Sodium Thiosulfate at 40% (PVC, EPDM), Sulfuric Acid at 98% (CPVC, Viton), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water up to 10 PPM (PVC, EPDM). Cross-check your chemistry in the Chemical Compatibility Database before you commit.
The mistake to avoid
The big error on a cone tank this size is matching the fitting and gasket to the tank instead of to the chemical. The HDLPE shell tolerates this whole list at 1.9 SG, but the bulkheads and gaskets do not behave the same way. Oxidizers and strong acids per the chart, including sodium hypochlorite, hydrochloric, phosphoric, and hydrogen peroxide, all call for Viton, while 98% sulfuric needs CPVC and peracetic acid needs Aflas; most salts and glycols run on EPDM. Put an EPDM gasket on a Viton chemistry and it swells and degrades, and you get a slow seep at the discharge valve. The second mistake is stand selection on a full-drain cone, so review the Cone Bottom Tank Stand Compatibility Matrix, plan level monitoring with the level gauge selection guide, and label the tank correctly per the bulk polyethylene signage compliance guide. If your application also needs spill containment, compare options in the Snyder Captor Plus 110% containment vs UL-142 comparison.
