The Snyder Industries 1000 Gallon XLPE Heavy Duty Cone Bottom Tank is built for chemistry duty: a crosslinked linear polyethylene (XLPE) shell rated to 1.9 specific gravity, standing 103 inches tall on a 64 x 64-inch footprint. Crosslinking changes how this tank handles aggressive contents - if you are weighing it against a standard HDPE cone, the Snyder XLPE vs HDPE guide walks through where the difference earns its keep. The cone bottom drains down toward the outlet, which is what you want when you are dosing, batching, or fully emptying a chemical between runs - one reason this is a workhorse for DEF and water-treatment skids.
Does it work for your application?
The cone bottom geometry holds 1000 gallons of usable volume in black XLPE. The 1.9 SG rating is the number that governs what you can store: it tells you the heaviest contents this tank is built to carry. Filled with plain water the load is about 8,340 pounds, but at the full rated contents weight the tank is engineered for roughly 15,846 pounds - so a dense chemical at high specific gravity is well within range. Factory fittings per the technical drawing include a flange, an 18-inch PE threaded and vented opening, and a manway with 15-inch access for entry and cleaning. See the technical drawing on this page for exact fitting placement, and use the Tank Sizing Calculator and Tank Sizing Guide to confirm the cone, the contents weight, and your stand all line up before you order. Every cone bottom tank rides on a matched support stand, and the single most common install failure is undersizing it: your stand must be rated for the full contents weight - up to roughly 15,846 pounds at 1.9 SG - not just the empty tank. The cone bottom stand compatibility matrix and the 1000 gallon 45 degree cone bottom buyer's guide are worth reading before you finalize the build.
Chemical compatibility
This is an XLPE tank rated to 1.9 specific gravity. XLPE resists stress cracking and a broad range of chemistries that would shorten the life of a standard HDPE wall, but resin and SG only get you part of the way - the fittings and gaskets have to match the chemical too. Confirm every selection against the OEM chemical-resistance chart for your exact concentration and operating temperature before committing to chemical service. Watch three rows that break the default PVC-plus-EPDM pattern: DEF wants 316 stainless fittings, hydrofluosilicic acid needs Viton gaskets instead of EPDM, and propylene glycol calls for PP or 316SS. Based on the compatibility data for this tank, the following are supported (with the recommended fitting and gasket materials):
- Acetic Acid at 60% - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate at 50% - PVC fittings, EPDM gaskets
- Calcium Chloride at 40% - PVC fittings, EPDM gaskets
- DEF at 32.5% - 316SS fittings, EPDM gaskets
- Ethylene Glycol at 100% - PVC fittings, EPDM gaskets
- Ferric Chloride at 50% - PVC fittings, EPDM gaskets
- Ferric Sulfate at 60% - PVC fittings, EPDM gaskets
- Ferrous Sulfate at 20% - PVC fittings, EPDM gaskets
- Hydrofluosilicic Acid at 26% - PP/PVC fittings, Viton gaskets
- Magnesium Chloride at 30% - PVC fittings, EPDM gaskets
- Polyaluminum Chloride (concentration not specified - confirm your operating concentration) - PVC fittings, EPDM gaskets
- Potassium Carbonate at 50% - PVC fittings, EPDM gaskets
- Potassium Hydroxide, saturated - PVC fittings, EPDM gaskets
- Propylene Glycol (concentration not specified - confirm your operating concentration) - PP/316SS fittings, EPDM gaskets
- Sodium Carbonate at 30% - PVC fittings, EPDM gaskets
- Sodium Thiosulfate at 40% - PVC fittings, EPDM gaskets
- Urea Solution at 50% - PP/PVC fittings, EPDM gaskets
- Ozonated Water up to 10 PPM - PVC fittings, EPDM gaskets

The mistake to avoid
The trap on this specific tank is assuming the resin alone clears your chemical. This is XLPE - crosslinked, not standard HDPE - so do not substitute compatibility data from an HDPE cone tank. Match the SG of your contents to the 1.9 rating, then match the fitting and gasket materials above to your exact chemical and concentration. A PVC fitting where 316SS is specified for DEF, or EPDM where Viton is called for on hydrofluosilicic acid, will leak long before the tank wall ever does.
