The Enduraplas 5000 Gallon White Cone Bottom Tank (SKU THC05000W) is a 5,000-gallon polyethylene cone-bottom vessel built for full-drain chemical and process service. It stands 166 inches tall on a 110 x 110 inch footprint, molded in natural white. The cone-bottom geometry empties completely, which matters when you are batching, settling solids, or switching products and need no residual heel left in the tank.
Will it work for your application
This cone bottom tank carries a 1.9 specific gravity rating, which is the headline number for chemical buyers. Filled with plain water (SG 1.0) it holds about 41,700 pounds of contents; at the full 1.9 rating it is engineered to carry up to 79,230 pounds of product. That spread is exactly why SG matters: a tank's specific gravity rating must meet or exceed the true specific gravity of the chemical you intend to store. At 1.9, this rating sits at the top of the poly cone-bottom range and covers essentially every aqueous chemical on the list below, so there is no "do I need to size up" question to chase. Cross-check your chemical's true specific gravity against the 1.9 rating with the Tank Sizing Calculator and the Tank Sizing Guide before you commit. Because this is a cone bottom design, it needs a matching stand to support the cone and keep the tank stable when full - see our Cone Bottom Tank Stand Compatibility Matrix for the right stand by manufacturer. Outlet size, bulkhead, and vent fittings are configured per order, so confirm those with our team at 866-418-1777; the technical drawing on this page shows the dimensional detail. For level instrumentation on aggressive chemicals, our guide to tank level gauge selection for chemical service walks through radar, ultrasonic, hydrostatic, and magnetostrictive options.
Chemical compatibility
This is an Enduraplas polyethylene tank rated to 1.9 specific gravity. Confirm the resin grade - HDLPE versus XLPE - with us before chemical service, since the resin determines which chemicals and concentrations are safe long term. Always verify against the OEM chemical-resistance chart, which is concentration- and temperature-specific. Within this tank's rating, the following chemicals are compatible at the stated concentrations and require the listed fitting and gasket materials: Acetic Acid 60% (PP/PVC fittings, EPDM gaskets), Aluminum Sulfate 50% (PVC, EPDM), Calcium Chloride 40% (PVC, EPDM), DEF 32.5% (316SS, EPDM), 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, Viton), Urea Solution 50% (PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water up to 10 PPM (PVC, EPDM). Gasket choice is not optional - sodium hypochlorite, sulfuric acid, hydrogen peroxide, and the strong acids require Viton, peracetic acid requires Aflas, and DEF and peracetic call for 316SS hardware; everything else runs PVC with EPDM. Tell us your chemical and we will spec the matching fitting and gasket materials from the table above. Full details and additional chemicals are in our Chemical Compatibility Database.
Freight and siting
This tank ships LTL freight from a single origin - the Enduraplas plant in Neche, ND - so anyone far from North Dakota should pull a live ZIP quote before ordering. Plan your site around the hard numbers: a 110 x 110 inch footprint and up to 79,230 pounds of contents at full 1.9-SG chemical load, which the pad or foundation must carry. Because of its 166-inch height and 5,000-gallon size this is a dedicated freight shipment, not a parcel item - get an exact number with our Freight Cost Estimator. The biggest mistake on a cone bottom tank this size is ordering the vessel without the matching cone stand or specifying the wrong gasket for your chemical; confirm both with our team. Call 866-418-1777 to lock in fittings, stand, and freight.
