The Snyder Industries 1250 Gallon Heavy Duty Cone Bottom Tank is a full-drain vessel for bulk chemical storage and batching, molded in black polyethylene with a 1.9 specific gravity rating. The cone-bottom geometry forces complete discharge with no settled heel, which is why operators reach for a cone tank when dosing coagulants, glycols, or acids that stratify or carry suspended solids. It stands 70 inches tall on a 95 x 95 inch footprint, so you will need a matching cone-bottom stand to support it off the floor and a clear discharge path beneath the cone.

Will it hold your chemical?
The 1.9 specific gravity rating is the number that matters here. Empty of its stand, the tank holds 1,250 gallons; filled with plain water it carries 10,425 pounds, and at its maximum rated contents it is built to carry 19,808 pounds. That spread between water weight and rated weight is the 1.9 SG headroom, and it is what lets this tank hold dense liquids that a standard 1.0 or 1.5 SG tank cannot. The 1.9 SG rating is the heavy-duty ceiling for this geometry; match your chemical's specific gravity against it, and note there is no higher-rated step-up in this size and style. Size the supporting stand and pad to the full 19,808 pound rated load, not the water figure.
Chemical compatibility
This is a black polyethylene tank rated to 1.9 specific gravity. The resin is unconfirmed in our records, so confirm the exact resin with our team before committing it to chemical service. Compatibility is always concentration and temperature specific. Verify your exact chemical against the OEM chemical-resistance chart for the concentration and temperature you actually run, and match the fitting and gasket materials below to the same service.
At the 1.9 SG rating this tank is suited to the following, all of which fall within its specific gravity ceiling:
- 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 (under 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
Note the gasket spread: oxidizers like sulfuric acid, hydrogen peroxide, sodium hypochlorite, and the fluoride acids call for Viton or Aflas, while the salts and glycols run fine on EPDM. Sodium hypochlorite in particular is concentration-sensitive on a polyethylene tank, so keep it under 16.5% and confirm the fitting and venting against the chart. The full Chemical Compatibility Database carries the concentration and temperature detail for each of these.
The mistake to avoid
The costliest error on a cone-bottom tank this size is treating the 1.9 SG rating as a license to skip the chemistry check. The rating governs structural load, not chemical attack - a tank can carry the weight of a dense acid and still degrade if the fitting and gasket materials are wrong for that acid. Pair every chemical with its listed fitting and gasket material above, confirm the resin with our team before service, and never assume a cone tank self-vents. The cone bottom also means this tank cannot stand on its own; budget for the cone-bottom stand at the same time. See the technical drawing on this page for fitting locations and overall dimensions, and use the Tank Sizing Calculator and Tank Sizing Guide to confirm capacity against your batch volume. The cone bottom tank stand compatibility matrix covers Snyder stand pairing, and the level gauge selection guide and hazard labeling and signage guide round out the dosing setup.
This tank ships LTL freight from Snyder's plant in Marked Tree, Arkansas, quoted live to your ZIP. Because the origin is fixed and the unit is large and heavy at 19,808 pounds rated on a 95 x 95 inch footprint, distant ZIPs should run the numbers early.
