The Snyder Industries 2000 Gallon Vertical Double Wall Liquid Chemical Storage Tank is built for primary-plus-secondary containment of aggressive chemicals, with a 1.9 specific gravity rating that puts it at the top of the SG range for double wall tanks in this capacity. The inner tank holds 2,000 gallons; the integral outer wall captures a leak before it reaches your floor or the environment, which is exactly what an SPCC or 40 CFR 112 plan calls for. Molded from High Density Linear Polyethylene in white, this vertical double wall storage tank stands 103 inches tall on a 102 by 102 inch footprint. Here is the simple buying filter: if your chemical's specific gravity exceeds 1.5 at operating temperature, a standard tank is under-rated for full fill, and this 1.9-rated tank is not.
Will this tank work for your chemical?
Confirm two things before you order: weight and chemistry. Filled with plain water, this storage tank carries roughly 16,680 lb, but the 1.9 SG rating means the inner tank is engineered to hold up to about 31,692 lb of contents at maximum rated density. That loaded weight over the 102 by 102 inch footprint (about 72 square feet) works out to roughly 440 lb per square foot of bearing load, which is the number your slab, ring, or pad engineer actually sizes to, not the empty shell. Use the Tank Sizing Calculator and Tank Sizing Guide to match capacity, headspace, and pad loading to your install. If you are storing DEF at 32.5 percent or a 50 percent urea solution, this double wall tank is rated for both, which makes it a clean fit for fleet, fueling, and emissions applications as well as water-treatment chemistry.
Chemical compatibility
This is an HDLPE tank rated to 1.9 specific gravity, so it carries dense chemistries that a standard 1.5 SG tank cannot hold at full fill. Always confirm the chemical-resistance match against the OEM chemical-resistance chart at your specific concentration and operating temperature, and spec the wetted fittings and gaskets accordingly. Each chemistry below links to its own compatibility page so you can verify the exact concentration and material call before you plumb anything. Verified compatible chemistries for this tank include:
- 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 (<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 most common error on a double wall chemical tank is matching the gasket to the tank instead of to the chemical. Notice that Hydrochloric Acid, Hydrogen Peroxide, Phosphoric Acid, Sulfuric Acid, and Sodium Hypochlorite all call for Viton rather than the EPDM used on the salt solutions; Sulfuric Acid steps up to CPVC fittings, and Peracetic Acid needs 316SS with Aflas. Putting an EPDM gasket on a Viton-rated acid is how a brand-new tank starts weeping at the bulkhead. Click through to the per-chemical compatibility page for your exact fluid, confirm fitting and gasket material against the OEM chart at your concentration and temperature, and spec from there. If you are building this tank into a containment plan, the Snyder Captor double-wall SPCC walkthrough covers how this style of tank fits 40 CFR 112.
