The Enduraplas 8000 Gallon White Cone Bottom Tank with Stand (SKU THC08000KW) is a full-drain vessel built for high-density chemical batching, mixing, and storage where you need the tank to empty completely. It carries a 1.9 specific gravity rating in natural white polyethylene, stands 166 inches tall on a 144-inch diameter footprint, and ships with a 16-inch threaded vented manway up top and a 3-inch PP female NPT bulkhead outlet at the cone tip. Empty weight is 2,100 lb. Enduraplas builds this tank FDA approved, and the cone-and-stand design lets you gravity-feed or pump-out without leaving heel volume behind.
Will it hold your product
The 1.9 SG rating is the number that matters. Filled with plain water this 8000 gallon tank carries roughly 66,720 lb; loaded to its rated 1.9 SG it is engineered for contents up to about 126,768 lb. Match the tank rating to the density of what you are actually storing, not just the gallon figure. If you are sizing a batch or comparing this against a smaller vessel, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide. Choosing the steel-vs-poly stand under a cone this size is its own decision, walked through in our stand selection decision tree and the Norwesco, Snyder and Enduraplas compatibility matrix. See the technical drawing on this page for the full dimensional layout.
Chemical compatibility
This is a polyethylene tank rated to 1.9 specific gravity. The resin is recorded as HDLPE with a caveat — confirm HDLPE versus XLPE with us before you commit it to chemical service, since crosslinked and linear polyethylene behave differently with aggressive oxidizers. Compatibility below is drawn from the Snyder Industries OEM chemical resistance chart and is concentration- and temperature-specific; confirm your exact chemical, concentration, temperature, and fitting plus gasket material before ordering. One detail that trips buyers up: this tank ships with a 3-inch PP bulkhead outlet, but many chemicals on the chart call for a PVC, CPVC, or 316SS fitting instead — where the pairing below names one of those, plan on a matching outlet and bulkhead swap.
At this tank's 1.9 SG rating the chart supports service with Ethylene Glycol (100%), Ferric Chloride (50%), Ferric Sulfate (60%), Hydrochloric Acid (37%, PVC/Viton), Hydrofluoric Acid (48%, PP or PVC/Viton), Hydrofluosilicic Acid (26%, PP or PVC/Viton), Hydrogen Peroxide (50%, PVC/Viton), Peracetic Acid (30%, 316SS/Aflas), Phosphoric Acid (85%, PVC/Viton), Polyaluminum Chloride, Potassium Carbonate (50%), Potassium Hydroxide (saturated), Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Hypochlorite (under 16.5%, PVC/Viton), Sodium Thiosulfate (40%), Sulfuric Acid (98%, CPVC/Viton), and Zinc Orthophosphate. Lighter-duty chemicals the chart clears at a 1.5 SG tank — Acetic Acid (60%), Aluminum Sulfate (50%), Calcium Chloride (40%), Ferrous Sulfate (20%), Magnesium Chloride (30%), Sodium Carbonate (30%), and Ozonated Water (up to 10 PPM, detail page pending) — are well within this 1.9 SG tank. DEF (32.5%) is rated at 1.35 SG and specifically needs 316SS fittings — the stock PP outlet will not satisfy it — while Urea Solution (50%) runs on PP/PVC at 1.35 SG. The pairings above call out the fitting material (PVC, CPVC, PP, 316SS) and gasket (EPDM, Viton, Aflas) that go with each chemical — get both right.

Freight and ordering
This 8000 gallon cone bottom tank ships LTL freight from the nearest Enduraplas plant — Neche, ND or Converse, TX — quoted live to your ZIP. Before the truck arrives, verify your site against the real dimensions: at 166 inches tall (about 13.8 ft) on a 12-ft diameter footprint, confirm overhead clearance, the pad size, and any door or gate access on the delivery path. Get a freight number in seconds with our Freight Cost Estimator, or call 866-418-1777 and we will confirm resin, fittings, stand, and delivery for your site. Confirm HDLPE versus XLPE with us before chemical service so the tank matches your product from day one.
