The Snyder Industries 1250 Gallon Heavy Duty Cone Bottom Tank is a 1.9 specific-gravity cone-bottom vessel built for full-drain chemical service. Molded in natural white polyethylene, the 1250-gallon body stands 70 inches tall on a 95 x 95 inch footprint, and the cone profile drains the tank completely so you are not left fighting settled solids or a sludge heel at the bottom. The 1.9 SG rating is the number that matters here: it tells you this tank is engineered to hold dense liquids well beyond the weight of water, which is exactly what cone bottom chemical applications demand. This is a Snyder-built cone tank, and it ships LTL from Snyder's Marked Tree, Arkansas plant - a central lane that keeps freight reasonable across most of the lower 48.
Will this tank handle your liquid?
Sizing is about weight, not just volume. Filled with water this tank carries roughly 10,425 lb, but at its maximum rated contents it is engineered for up to 19,808 lb - that headroom is what lets you run heavier-than-water chemicals safely. Always confirm your chemical's specific gravity against the 1.9 rating before you fill. For liquids above 1.9 SG, call 866-418-1777 and we will spec a heavier-rated or alternate-material vessel rather than push this one past its limit. Because a cone bottom tank cannot stand on its own, it requires a matching stand or structural support - work through the Cone Bottom Tank Stand Compatibility Matrix and the Tank Sizing Calculator before you commit. Fitting sizes and outlet locations are shown on the technical drawing on this page and confirmed at order, so don't assume a standard outlet until you have checked it against your plumbing.
Chemical compatibility
This is a 1.9 SG polyethylene cone bottom tank. The resin is recorded as HDLPE - confirm HDLPE versus XLPE with us before chemical service, because crosslinked and linear polyethylene resist different chemistries, and we will verify the exact resin grade against your chemical before you order. The pairings below come from the OEM chemical-resistance chart and are concentration- and temperature-specific; verify your exact conditions before ordering fittings or gaskets.
| Chemical | Max concentration | Fitting | Gasket |
|---|---|---|---|
| Acetic acid | 60% | PP/PVC | EPDM |
| Aluminum sulfate | 50% | PVC | EPDM |
| Calcium chloride | 40% | PVC | EPDM |
| DEF | 32.5% | 316SS | EPDM |
| Ethylene glycol | 100% | PVC | EPDM |
| Ferric chloride | 50% | PVC | EPDM |
| Ferric sulfate | 60% | PVC | EPDM |
| Ferrous sulfate | 20% | PVC | EPDM |
| Hydrochloric acid | 37% | PVC | Viton |
| Hydrofluoric acid | 48% | PP/PVC | Viton |
| Hydrofluosilicic acid | 26% | PP/PVC | Viton |
| Hydrogen peroxide | 50% | PVC | Viton |
| Magnesium chloride | 30% | PVC | EPDM |
| Peracetic acid | 30% | 316SS | Aflas |
| Phosphoric acid | 85% | PVC | Viton |
| Polyaluminum chloride | - | PVC | EPDM |
| Potassium carbonate | 50% | PVC | EPDM |
| Potassium hydroxide | Saturated | PVC | EPDM |
| Propylene glycol | - | PP/316SS | EPDM |
| Sodium bisulfate | - | PVC/PP | EPDM |
| Sodium bisulfite | - | PVC/PP | EPDM |
| Sodium carbonate | 30% | PVC | EPDM |
| Sodium hypochlorite | <16.5% | PVC | Viton |
| Sodium thiosulfate | 40% | PVC | EPDM |
| Sulfuric acid | 98% | CPVC | Viton |
| Urea solution | 50% | PP/PVC | EPDM |
| Zinc orthophosphate | - | PP/316SS | EPDM |
| Ozonated water | up to 10 PPM | PVC | EPDM |
Notice how the hardware changes with the chemistry: sodium hypochlorite and the strong acids call for Viton, peracetic acid needs Aflas, and DEF, peracetic acid, propylene glycol, and zinc orthophosphate move to 316SS - so match your fittings and gaskets to your liquid, not to a generic spec. Cross-check every chemical against our Chemical Compatibility Database.
The mistake to avoid
The most common error on a high-SG cone bottom tank is mismatched fittings and gaskets. The 1.9 SG rating means the polyethylene wall can hold the weight, but the wrong gasket on an aggressive chemical fails long before the tank does - so use the per-chemical fitting and gasket materials above, not a generic EPDM bulkhead on everything. For heavier-than-water service, confirm gauge and signage requirements too; the level-gauge selection guide and the tank label and signage compliance guide walk through the right hardware and placarding for bulk polyethylene chemical storage.
