The Snyder Industries 35 Gallon Sulfuric Acid Double Wall Tank (SKU 1000112N30) is a compact chemical-containment vessel built for dense, aggressive liquids. Molded in HDLPE #880046 and rated to a 1.9 specific gravity, this 35 gallon double wall tank nests the primary tank inside an integral secondary basin, so spill capture is engineered into the unit rather than added around it. At 36 inches tall on a tight 22 x 22 inch footprint, it slides into pump rooms, dosing skids, and containment corners where floor space is scarce.
Will it work for your job?
Start with the specific gravity math, because on a Snyder double wall tank that is where sizing lives or dies. Filled with plain water the tank carries about 292 pounds. The 1.9 rating is the contents ceiling: at full volume it is engineered to hold liquid weighing up to roughly 555 pounds. That headroom is exactly why this tank is spec'd for concentrated sulfuric acid, which runs near 1.84 specific gravity and lands right at the tank's design limit rather than beyond it. Size from the density of the fluid you are actually storing, not from gallons alone. Run the loaded weight through the Tank Sizing Calculator and the Tank Sizing Guide, and confirm your stand or pad is rated for it before you set the tank. See the technical drawing on this page for exact fitting locations, wall dimensions, and containment volume.
The mistake to avoid
The most common error on a high-SG containment tank is treating the specific gravity number as optional. A tank rated to 1.9 is the ceiling in this family, and substituting a lower-rated shell because it looked cheaper is how buyers end up with bulging walls and a failed basin. Match the 1.9 rating to your fluid's density. Just as important, do not assume the fittings and gaskets are sorted out of the box: elastomer selection for sulfuric acid service (Viton versus EPDM, for example) is a per-install call driven by your concentration and temperature, and it should be spec'd deliberately rather than defaulted. Call 866-418-1777 and we will walk the fitting and gasket layout with you before the tank ships.
Containment and compliance
The double wall design gives you built-in secondary containment, which supports SPCC planning, but it does not replace the regulatory review itself. If this tank is going into an oil or chemical storage program, read the SPCC 40 CFR 112 walkthrough and the freeboard sizing guide per ASTM D1998 to confirm usable volume and freeboard before you finalize the size. For the pad underneath it, the concrete pad sizing framework covers the loaded-weight case.
Freight and ordering
This tank ships LTL freight from the Snyder plant in Marked Tree, Arkansas, and freight is quoted live to your ZIP rather than baked into the list price. Get a real number in seconds with the Freight Cost Estimator, or call 866-418-1777 and we will confirm the 1.9 specific gravity match, sort the fitting and gasket spec for your chemistry, and quote freight to your dock.
