The Snyder Industries 5000 Gallon Plastic Vertical Double Wall Liquid Chemical Storage Tank in white is built for one job: holding aggressive liquids inside a secondary containment shell wrapped around the primary tank, so a primary leak is caught instead of spilled - the configuration the Snyder Captor double-wall walkthrough for SPCC 40 CFR 112 is built around. It molds from high-density linear polyethylene (HDLPE) and carries a 1.9 specific gravity rating, which is the figure that tells you whether your chemical is too dense for this shell. The primary tank measures 102 inches in diameter and stands 216 inches tall, on a 102.0 x 102.0-inch footprint. That diameter matters before you order: confirm your doorway, pad, and overhead clearance against the technical drawing on this page before freight is booked.
Will it work for your liquid?
The 1.9 specific gravity rating is the load ceiling. Filled with water (SG 1.0) the contents weigh 41,700 lb; at the full 1.9 rating the tank is engineered to carry up to 79,230 lb of contents. Stay at or under SG 1.9 for whatever you store and you are inside the design envelope - but heavy services sit close to that line, so confirm your operating SG first: 98% sulfuric acid runs near 1.84, leaving little margin at this vertical double wall tank's top rating. The drawing fittings on this unit include a flange, an 18-inch PE threaded/vented fitting, and a manway with a 15-inch access opening for cleaning, entry, and inspection. Fitting positions and sizes here are drawing-governed, so confirm the 15-inch manway access against the technical drawing on this page. The vented connection is not optional on a chemical fill point: outgassing or rapid fill without proper venting can deform a poly shell. If you are still mapping capacity to your draw rate, the Tank Sizing Calculator and Tank Sizing Guide walk you through it.
Chemical compatibility
This is an HDLPE tank rated to 1.9 specific gravity. The chemicals below are matched to this resin at the noted concentration, with the suggested fitting and gasket materials for each - build the full spec for every connection from the Chemical Compatibility Database. Always verify against the OEM chemical-resistance chart for your exact concentration and operating temperature before committing to a service, and link through to each chemical page for the full detail.

Notice how the gasket and fitting material shifts with the chemical: oxidizers and strong acids like sulfuric, hydrochloric, hydrofluoric, hydrogen peroxide, and sodium hypochlorite call for Viton or CPVC instead of EPDM and PVC. The single most common mistake on a tank like this is matching the polyethylene shell correctly but leaving an EPDM gasket on a Viton-required chemical, which fails at the seal long before the tank does. Sodium hypochlorite (bleach) also degrades over time, so size and turn over your inventory accordingly.
Freight and ordering
This vertical double wall storage tank ships LTL from Snyder's plant in Lincoln, NE, freight quoted live to your ZIP - get a number now with the Freight Cost Estimator or call 866-418-1777. At 102 inches wide and 216 inches tall this is an oversized load; confirm the receiving site has the clearance and equipment to offload before it leaves the dock. To instrument it correctly, the tank level gauge selection guide for chemical service compares radar, ultrasonic, hydrostatic, and magnetostrictive options. Two related single-wall 5000-gallon configurations in different footprints - the 119 x 86 natural white and 141 x 86 natural white guides - cover sizing tradeoffs, though both differ in build and dimensions from this 102 x 216 double wall white tank.
