The 2600 Gallon 45 Degree Plastic Cone Bottom Tank from Snyder Industries is a full-drain processing vessel built for chemical service. The complete 45-degree cone discharges solids, slurries, and heavy liquids without leaving a heel, and the 1.9 specific gravity rating means it is built to hold dense chemistry that would over-stress a standard water-grade tank. Molded in white polyethylene, this cone tank stands 139 inches tall on a 90 x 90 inch footprint and holds 2,600 gallons.
Will it work for your application?
On a cone bottom tank like this, the 1.9 SG rating is the headline number: it tells you the maximum density of fluid the tank wall is rated to carry. At full water (specific gravity 1.0) this tank carries 21,684 pounds. At its maximum rated contents weight it is built to hold 41,200 pounds, which is what lets it safely store the dense acids and salt solutions covered below. Match your chemical's specific gravity against that 1.9 ceiling before you buy. Because a cone bottom tank carries its load on a support stand rather than a flat slab, the real-world failure mode is undersizing the structure: confirm your stand rating and concrete pad are sized for the full 41,200 lb of max rated contents, not just the full-water weight. Budget for the height too: at 139 inches this is a tall vessel that needs overhead clearance for fill lines and room for the cone-and-stand assembly underneath for discharge plumbing. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm capacity and loaded weight against your space.
Chemical compatibility
This is a 1.9 SG polyethylene cone bottom tank. The exact resin grade is not confirmed in our data, so verify whether your application requires linear (HDLPE) or crosslinked (XLPE) polyethylene before chemical service, because the two resins resist different chemistries and that difference is load-bearing for the oxidizers below. Compatibility also depends on matching the right fitting and gasket materials, and every rating here is concentration- and temperature-specific. This tank is not pre-plumbed with a fixed fitting package; the bulkhead, outlet, and gasket layout on the cone are specified to your chemistry at quote time, so plan those alongside the chemical. Confirm your exact chemical, concentration, and operating temperature against the Snyder OEM chemical-resistance chart for this tank before service.
The single most preventable mistake on a chemical tank is specifying the wrong elastomer: notice how the gasket material shifts with the chemistry below. EPDM covers most salts and bases, but oxidizers and strong acids step up to Viton, and peracetic acid steps up again to Aflas. At this tank's 1.9 SG rating, the following chemicals are compatible when plumbed with the noted fitting and gasket materials:
- 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

The mistake to avoid
The costliest error on a tank this size is treating the 1.9 SG rating as a formality. It is the structural limit. A standard 1.0 or 1.5 SG cone tank filled with a dense salt or acid solution can fail at the wall, so always confirm your fluid's specific gravity sits at or below 1.9 and that your fittings and gaskets match the chart, not just the tank. For deeper background on choosing cone angle and stand configuration, see our Cone Bottom Tank Buyer's Guide on 15 vs 30 vs 45 degree selection, and review the technical drawing on this page for fitting locations and exact dimensions.
