The Enduraplas 2520 Gallon Black Cone Bottom Tank is a full-drain polyethylene vessel engineered for bulk chemical service, and it carries the top 1.9 specific gravity rating offered in this cone line. That rating is the headline fact: at 1.9 SG there is no heavier-density tank to step up to, so by weight this vessel covers essentially any liquid chemical solution you would store in polyethylene. Standing 99 inches tall on a 110 x 110-inch footprint and holding 2,520 gallons, it is the cone bottom tank buyers reach for under searches like cone tank and Enduraplas cone bottom when complete gravity discharge is the point.
Will this cone bottom tank handle your contents?
The load math is the proof behind the 1.9 claim. Full of water this tank weighs 21,017 lb, but it is rated to support 39,932 lb of contents - roughly 1.9 times the water weight, which is exactly what a 1.9 SG rating means in practice. That headroom is what lets it hold dense solutions that would overload a 1.5 SG tank. Verify your fluid's specific gravity against the 1.9 rating before you order. Because the cone geometry is self-emptying and offers no flat base, this tank requires a matched steel stand rated to that 39,932 lb maximum load; the 110 x 110-inch footprint and 99-inch height also drive stand sizing and overhead clearance for fill and vent plumbing. Confirm volume and headroom with our Tank Sizing Calculator and Tank Sizing Guide, and size the stand against our cone bottom tank stand compatibility matrix.
Chemical compatibility
This is a polyethylene tank with a 1.9 SG rating. The resin family is listed as HDLPE; because crosslinked (XLPE) and linear (HDLPE) polyethylene differ in resistance to specific chemistries, we confirm the exact resin in writing for your chemistry before order - one call to 866-418-1777 settles it. The chemicals below come from the OEM chemical-resistance chart and are concentration- and temperature-specific; match your exact concentration and operating temperature to the chart, and pair the tank with the fitting and gasket materials shown:
- 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 (<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
The elastomer is not interchangeable. Sodium hypochlorite, sulfuric acid, hydrogen peroxide, and phosphoric acid each require Viton, and peracetic acid requires Aflas - never substitute EPDM on those to save cost.

Outfitting and avoiding the common mistake
The most expensive error on a cone bottom tank this size is mismatching the bulkhead fitting and gasket to the chemical - pairing a Viton-required acid like 98% sulfuric (CPVC + Viton) or 316SS + Aflas peracetic acid with the wrong elastomer. Tell us your exact chemical and concentration at order so we match the fitting and gasket to the chart above. Plan your top penetrations - vent, fill, level sensing - before installation with our tank top fitting placement strategy, choose a gauge with our tank level gauge selection guide, and label the vessel correctly per our tank label and signage compliance guide. Reference the technical drawing on this page for exact dimensions and discharge geometry.
