The Enduraplas 2500 Gallon Green Cone Bottom Tank (SKU THC02500G) is a full-drain vessel built for chemical service, molded in green polyethylene with a 1.9 specific gravity rating. The cone bottom forces complete discharge of slurries, settling solids, and concentrated chemicals that flat-bottom tanks leave behind. At 2,500 gallons in a 90 inch by 90 inch footprint and 120 inches tall, it suits operators searching for a cone bottom tank, cone tank, or 2500 gallon cone configuration where a stand carries the load.
Does it work for your application?
This tank carries a 1.9 specific gravity rating, which is the heavy-duty end of the range and the reason it handles dense chemicals rather than just water. That 1.9 is the maximum rating offered in this configuration, so if your medium is denser than 1.9 SG, verify your specific gravity directly against that number before ordering. Plan your support structure around real weight, not nominal capacity. Filled with water (SG 1.0) the contents alone run about 20,850 lb; at the full 1.9 rating the tank can carry up to roughly 39,615 lb of contents. Those numbers drive the cone bottom stand you select. Review the Cone Bottom Tank Stand Compatibility Matrix and the 2500 Gallon Cone Bottom Tank buyer's guide before you order a stand, and confirm overall height and the 90 x 90 inch footprint against your pad and ceiling using the technical drawing on this page. The Tank Sizing Calculator and Tank Sizing Guide help you confirm 2,500 gallons is the right working volume. One note on freight before you buy: this tank ships from two plants, Converse, TX and Neche, ND, and we quote from whichever is nearer your ZIP, so the TX/ND split can change your LTL cost meaningfully by region. Run the Freight Cost Estimator early to see your number.
Chemical compatibility
This tank is polyethylene with a 1.9 SG rating. One hard gate before chemical service: the resin type is unconfirmed in our data (HDLPE high-density linear versus XLPE cross-linked), and the two are not interchangeable for aggressive media, so for any oxidizer or strong acid on the list below you must call 866-418-1777 to confirm the actual resin before ordering. Fitting layout (outlet size, bulkhead, vent) is configured at order, so the per-chemical fitting and gasket data below tells you what materials to specify once that layout is set. The compatible chemicals come from our chemical compatibility database and are concentration and temperature specific; always match your exact concentration and operating temperature against the data:
- 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
- Ethylene Glycol (100%) - PVC fittings, EPDM gaskets
- Ferric Chloride (50%) - PVC fittings, EPDM gaskets
- Ferric Sulfate (60%) - PVC fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Hydrochloric Acid (37%) - PVC fittings, Viton gaskets
- Hydrofluoric Acid (48%) - PP/PVC fittings, Viton gaskets
- Hydrofluosilicic Acid (26%) - PP/PVC fittings, Viton gaskets
- Hydrogen Peroxide (50%) - PVC fittings, Viton gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Peracetic Acid (30%) - 316SS fittings, Aflas gaskets
- Phosphoric Acid (85%) - PVC fittings, Viton gaskets
- Polyaluminum Chloride - PVC fittings, EPDM gaskets
- Potassium Carbonate (50%) - PVC fittings, EPDM gaskets
- Potassium Hydroxide (saturated) - PVC fittings, EPDM gaskets
- Propylene Glycol - PP/316SS fittings, EPDM gaskets
- Sodium Bisulfate - PVC/PP fittings, EPDM gaskets
- Sodium Bisulfite - PVC/PP fittings, EPDM gaskets
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
- Sodium Hypochlorite (under 16.5%) - PVC fittings, Viton gaskets
- Sodium Thiosulfate (40%) - PVC fittings, EPDM gaskets
- Sulfuric Acid (98%) - CPVC fittings, Viton gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Zinc Orthophosphate - PP/316SS fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
Cross-check your exact media in the full Chemical Compatibility Database. Note that sodium hypochlorite, peracetic acid, and concentrated sulfuric acid call for Viton or Aflas gaskets rather than EPDM, and DEF and peracetic acid require 316 stainless rather than plastic fittings.
The mistake to avoid
The most common error on a tank like this is matching the gasket and fitting material to water habits instead of the chemical. EPDM works for many salts and glycols but fails on oxidizers; sodium hypochlorite, hydrogen peroxide, and the strong acids in the list above need Viton, and peracetic acid needs Aflas. Get the elastomer wrong and the fitting seal degrades long before the polyethylene wall does. The same discipline applies to the resin: because the rating is listed as HDLPE pending confirmation, an aggressive medium is a call-first situation, since an XLPE shell and an HDLPE shell are not interchangeable for every chemical.
This tank ships LTL freight from the nearest plant in our network - Converse, TX or Neche, ND - with freight quoted live to your ZIP. Get a number on the Freight Cost Estimator or call 866-418-1777 to confirm fitting layout, gasket selection, and the right cone bottom stand before you buy.
