The Enduraplas 8000 Gallon 15 Degree Plastic Cone Bottom Tank with Stand (SKU EP-THC08000K-BK) is built for high-volume batching, mixing, and full-drain dispensing where you need the tank to empty completely. The 15-degree cone bottom feeds solids and settled product to the 3-inch outlet at the base, and the metal stand holds the cone off the ground so you can plumb, valve, and drain by gravity. This is a black closed-top tank molded from polyethylene, rated to a specific gravity of 1.9, with an empty weight of 2,100 lb.
Will it work for your job?
The tank body measures 144 inches in diameter and stands 158 inches tall on its stand, so confirm your ceiling height and door clearance before ordering. At 8,000 gallons of plain water you are carrying 66,720 lb of contents, and at the full 1.9 specific gravity rating the contents can weigh up to 126,768 lb. That number drives everything downstream: your pad, your stand footing, and your anchoring all have to be engineered for the loaded weight, not the empty tank. Run your fill volume through the Tank Sizing Calculator and the Tank Sizing Guide to confirm the 8000-gallon 15-degree cone footprint matches your space. Note that all 8,000 gallons drain through the single 3-inch outlet at the cone tip — with heavy, high-SG product that is a slow gravity drain, so size your downstream valving and plumbing accordingly.
Chemical compatibility
This is a polyethylene tank carrying a 1.9 specific gravity rating. The resin code reads HDLPE?, so do not commit this tank to chemical service until we confirm in writing whether it is high-density linear polyethylene or cross-linked polyethylene (XLPE) for your specific chemical — that unconfirmed resin is the single biggest unknown on a chem duty. Compatibility is always concentration- and temperature-specific, and it depends on your fittings and gaskets as much as the tank wall. Because this wall is rated at the top of the range, it covers every chemical on the compatibility list with margin to spare, including the lighter SG-1.35 duties like DEF (32.5%) and Urea Solution (50%). Per the Snyder Industries OEM chemical resistance chart, this tank's 1.9 SG rating supports storage of chemicals including Ethylene Glycol (100%, PVC fittings, EPDM gaskets), Ferric Chloride (50%, PVC/EPDM), Hydrochloric Acid (37%, PVC fittings with Viton gaskets), Hydrofluoric Acid (48%, PP or PVC fittings with Viton), Hydrogen Peroxide (50%, PVC/Viton), Phosphoric Acid (85%, PVC/Viton), Sodium Hypochlorite (below 16.5%, PVC/Viton), Sulfuric Acid (98%, CPVC fittings with Viton), Peracetic Acid (30%, 316SS fittings with Aflas), and Ferric Sulfate (60%, PVC/EPDM). Lower-concentration duties such as Acetic Acid (60%), Calcium Chloride (40%), and Sodium Carbonate (30%) are covered as well. The single biggest mistake on a cone-bottom chem tank is matching the tank wall but ignoring the fitting and gasket materials — a PVC-compatible acid can still attack the wrong gasket at the outlet, and some duties change the hardware entirely: DEF (32.5%) and Peracetic Acid (30%) call for 316 stainless fittings, not PVC. Verify your exact chemical, concentration, temperature, and hardware against the Chemical Compatibility Database before ordering.
How it ships
Because of its 144-inch diameter and stand height, this tank ships LTL freight from the Enduraplas plant in Converse, TX, and freight is quoted live to your ZIP.
