The Snyder Industries 500 Gallon XLPE Heavy Duty Cone Bottom Tank is built for chemical-service duty where lighter polyethylene tanks fall short. Molded in crosslinked linear polyethylene (XLPE) with a 1.9 specific gravity rating, this 500 gallon cone tank carries dense liquids that a standard 1.0 SG tank cannot handle safely. It stands 63 inches tall on a 64 x 64 inch footprint and ships in natural white, so you can read your liquid level through the wall and spot sediment buildup or batch separation without opening the lid. The cone discharge drains the tank completely, which is why operators pairing it with a stand reach for this style for batching, mixing, and chemical metering.
Will it work for your application?
This is a 500 gallon tank with a 1.9 SG rating, meaning it is engineered to hold contents weighing up to roughly 7,923 pounds at full rated load. Plain water at this volume weighs about 4,170 pounds, so the rating leaves substantial headroom for heavier chemistry. The simple gate is specific gravity: contents weight equals volume times SG times 8.34 pounds per gallon, so any liquid up to about 1.9 SG is in spec at full volume. The 1.9 rating is the wall, and filling with a liquid heavier than that voids it, so confirm your chemistry's specific gravity before you order. Per the technical drawing on this page, the tank is fitted with a flange, an 18-inch PE threaded and vented opening, and a manway with 15-inch access. That manway is more than a fill port: the 15-inch access lets you inspect and clean the interior between chemical batches, which matters on a cone tank that gets switched between chemistries. The XLPE resin gives this cone tank better resistance to environmental stress cracking and stronger impact performance than single-wall HDPE, which counts when you store aggressive liquids. If you are weighing crosslinked against linear polyethylene for a given chemical, read our guide on Snyder XLPE vs HDPE before you specify. For sizing math, use the Tank Sizing Calculator and the Tank Sizing Guide, and see our 500 gallon 30 degree cone bottom tank buyer's guide for stand and plumbing detail. Because cone-bottom tanks need a support stand to drain, confirm your stand fit using the cone bottom tank stand compatibility matrix.
Chemical compatibility
This tank is XLPE with a 1.9 SG rating, so it accepts heavier chemistries than a standard polyethylene tank. Compatibility is concentration- and temperature-specific, so always confirm against the manufacturer's chemical-resistance chart for your exact conditions before filling. One watch-out before you spec hardware: two of the chemistries below break the default pattern. DEF (32.5%) calls for 316 stainless steel fittings, and hydrofluosilicic acid (26%) calls for Viton gaskets; everything else runs PVC or PP fittings with EPDM gaskets. For fleet operators, that DEF line means this tank handles diesel exhaust fluid storage cleanly when you spec 316 stainless hardware. Match your fitting and gasket to the chemical you are storing, not just to the tank. The following chemicals are compatible with this XLPE tank at the listed conditions:
- 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
- Hydrofluosilicic Acid (26%) — PP/PVC fittings, Viton gaskets
- Magnesium Chloride (30%) — PVC fittings, EPDM 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 Carbonate (30%) — PVC fittings, EPDM gaskets
- Sodium Thiosulfate (40%) — PVC fittings, EPDM gaskets
- Urea Solution (50%) — PP/PVC fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) — PVC fittings, EPDM gaskets

Freight and ordering
This cone bottom tank ships LTL freight from Lincoln, NE, quoted live to your ZIP code. Get an exact rate with the Freight Cost Estimator, or call 866-418-1777 and we will quote it and answer compatibility questions on your specific chemistry. The most common mistake on a tank like this is under-rating it: confirm your liquid's specific gravity does not exceed the 1.9 rating, and match your fittings and gaskets to the chemical per the chart above before you put it into service.
