The Enduraplas 1600 Gallon Green Cone Bottom Tank is built for full-drain chemical batching and processing, where you need the contents to empty completely under gravity rather than leaving a heel in the bottom. Molded from polyethylene in green and carrying a 1.9 specific gravity rating, this 1600-gallon cone tank stands 86 inches tall on a 90 x 90 inch footprint. That 1.9 SG rating is the headline: it is the top of the poly range and the whole reason to choose this tank over a standard water-grade vessel. It is engineered to hold dense chemical solutions, not just water.
Does this cone bottom tank work for my application?
Filled with water, this cone tank holds roughly 13,344 pounds; at its full rated capacity it is built to carry up to 25,354 pounds of contents. That spread between water weight and rated weight is exactly why the 1.9 specific gravity matters: it confirms the tank can handle liquids substantially heavier than water. Run your liquid's weight against that 25,354 lb ceiling with the Tank Sizing Calculator before you order, and use the Tank Sizing Guide if you are still settling on capacity. Because this is a cone bottom design, it requires a stand to elevate the cone for drainage; see our Cone Bottom Tank Stand Compatibility Matrix for Enduraplas-specific stand pairings, and the full 1600 gallon cone bottom with poly stand buyer's guide for a complete package walkthrough. Fitting size and placement are not pre-set on this listing, so confirm your outlet and bulkhead layout off the technical drawing on this page and with us at 866-418-1777 before ordering, especially since different chemistries call for different fitting materials.
Chemical compatibility
This is a polyethylene tank carrying a 1.9 SG rating. The resin is recorded as HDLPE pending confirmation, so verify HDLPE versus XLPE construction before placing this tank into chemical service, since crosslinked resin handles certain aggressive chemistries differently. Fitting and gasket selection drive long-term reliability as much as the tank wall does, so always match them to the OEM chemical-resistance chart, which is concentration and temperature specific. Examples this tank's SG rating supports, with the recommended fitting and gasket materials:
- Sodium hypochlorite (<16.5%) - PVC fittings, Viton gaskets
- Sulfuric acid (98%) - CPVC fittings, Viton gaskets
- Hydrochloric acid (37%) - PVC fittings, Viton gaskets
- Phosphoric acid (85%) - PVC fittings, Viton gaskets
- Hydrogen peroxide (50%) - PVC fittings, Viton gaskets
- Hydrofluoric acid (48%) - PP/PVC fittings, Viton gaskets
- Peracetic acid (30%) - 316SS fittings, Aflas gaskets
- DEF (32.5%) - 316SS fittings, EPDM gaskets
- Ferric chloride (50%), aluminum sulfate (50%), ferric sulfate (60%) - PVC fittings, EPDM gaskets
- Calcium chloride (40%), magnesium chloride (30%), ethylene glycol (100%) - PVC fittings, EPDM gaskets
- Potassium hydroxide (saturated), sodium carbonate (30%), urea solution (50%) - PVC or PP fittings, EPDM gaskets
This tank also supports acetic acid (60%), ferrous sulfate (20%), hydrofluosilicic acid (26%), polyaluminum chloride, potassium carbonate (50%), propylene glycol, sodium bisulfate, sodium bisulfite, sodium thiosulfate (40%), zinc orthophosphate, and ozonated water (up to 10 PPM). The buying decision hidden in this table is the gasket: EPDM is standard, but if you are storing any acid on this list - hydrochloric, sulfuric, phosphoric, hydrogen peroxide, hydrofluoric, or peracetic - you must specify Viton or Aflas at order time, and DEF and peracetic also call for 316 stainless fittings. Ordering the wrong gasket is the most common field failure on a chemical tank. Cross-check your exact chemical, concentration, and operating temperature in our Chemical Compatibility Database against the OEM chart before finalizing fittings.
The mistake to avoid
The most common error on a chemical cone bottom tank is matching the resin and SG to water service instead of your actual liquid. This tank carries a 1.9 SG rating for a reason; do not assume a lighter water-grade cone tank will survive a dense or aggressive chemistry, and do not reuse standard EPDM gaskets for chemistries like hydrochloric, sulfuric, phosphoric, or peracetic acid that require Viton or Aflas. Because the resin is logged as HDLPE pending confirmation, verify HDLPE versus XLPE before committing it to long-term chemical storage. For monitoring dense or hazardous contents, review our guide on level gauge selection for chemical service.
