The Snyder Industries 850 Gallon 15 Degree Cone Bottom Tank is a closed-top polyethylene cone bottom tank built for bulk chemical storage and full-drain dispensing. It carries a 1.9 specific gravity rating, which is the headline spec on this tank: that rating is what lets it hold dense liquids many cone bottom tanks can't. The 15-degree cone is the shallowest of the standard cone angles, discharging contents to a single low point so you can empty the tank cleanly without a pump dead-zone; the trade-off versus 30-degree and 45-degree cones is a longer drain time and a lower stand height. The 48 in x 48 in x 48 in tank envelope keeps the body compact for the stand or skid it sits on.
Will it work for your application?
Capacity is 850 gallons in a white polyethylene shell. Size your stand and pad off weight, not gallons. Filled with plain water this tank carries about 7,089 lb; at its 1.9 SG ceiling the contents alone reach roughly 13,469 lb — that is 1.9 times the weight of an equal volume of water, and it is contents-only, so your stand, anchor bolts, and slab must also carry the empty tank shell on top of that figure. Size everything off the liquid you actually intend to store. The 1.9 SG rating is what separates this Snyder cone tank from lower-SG cone bottom tanks; if your liquid exceeds 1.9 SG, polyethylene is the wrong material class for the job, so call us before you order. Use the Tank Sizing Calculator and our Tank Sizing Guide to confirm the cone tank size and stand match your throughput.
Chemical compatibility
This is a polyethylene tank rated to 1.9 specific gravity. The resin classification on file is listed as HDLPE (unconfirmed), so confirm the exact resin with us before committing to chemical service — the resin determines which chemicals and concentrations the tank wall will tolerate over time. Compatibility is always concentration- and temperature-specific, so verify your exact chemical against the OEM chemical-resistance chart before ordering. The following chemicals are documented as compatible with this tank at the listed concentrations, with the fitting and gasket materials that pair with each:
- 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 (tested concentration not on file)
- Potassium Carbonate (50%) - PVC fittings, EPDM gaskets
- Potassium Hydroxide (saturated) - PVC fittings, EPDM gaskets
- Propylene Glycol - PP/316SS fittings, EPDM gaskets (tested concentration not on file)
- Sodium Bisulfate - PVC/PP fittings, EPDM gaskets (tested concentration not on file)
- Sodium Bisulfite - PVC/PP fittings, EPDM gaskets (tested concentration not on file)
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
- Sodium Hypochlorite (<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 (tested concentration not on file)
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
The fitting and gasket call-outs are not one-size-fits-all, and getting them wrong is how a compatible tank still leaks. Oxidizers and strong acids — sulfuric, sodium hypochlorite, hydrogen peroxide, phosphoric, hydrofluoric, and hydrofluosilicic — call for Viton gaskets, and 98% sulfuric specifically wants CPVC fittings rather than plain PVC. DEF and peracetic acid step up to 316SS fittings, and peracetic acid is the one chemical here that requires an Aflas gasket. Everything else runs EPDM. Match the bulkhead fitting and gasket material to your chemical, not to whatever ships standard. Where the tested concentration isn't on file above, confirm it with us by phone before ordering rather than assuming.

The mistake to avoid
The costliest error on a 1.9 SG cone tank is treating the SG rating as optional. The rating means the tank wall is engineered to hold contents up to 1.9 times the weight of water; storing a heavier liquid is how walls fatigue and stands fail. Confirm both your chemical's specific gravity and its concentration against the 1.9 rating, and confirm the resin class for chemical duty before you commit. The second common miss is fitting placement: a cone bottom tank needs its vent, fill, level, and drain laid out to avoid cross-contamination and maintenance conflicts. Our tank top fitting placement strategy guide and the cone bottom tank stand compatibility matrix walk through both — and since this is the 15-degree cone, use the shallowest-angle row when you read the stand matrix. For containment-duty comparisons, see the Snyder Captor Plus 110% containment vs UL-142 comparison, and for cone-angle selection the 15-degree vs 30-degree vs 45-degree buyer's guide covers exactly where this 15-degree tank fits. Refer to the technical drawing on this page for the exact dimensions and fitting locations.
