The Snyder Industries 100 Gallon XLPE Vertical Chemical Storage Tank is built for one job: holding aggressive liquids that would degrade a standard water tank. It carries a 1.9 specific gravity rating, meaning the wall is engineered for contents up to 1.9 times the weight of water - the margin that separates a chemical-rated tank from a general-purpose one. At a 30 x 30 inch footprint and 41 inches tall, it tucks into tight equipment rooms and secondary-containment basins while leaving headroom to work the top fittings. It ships from a single plant in Philippi, West Virginia, so factor that origin into freight if you are in the West or Southwest.
Will it work for your application?
Water alone weighs 834 pounds at full volume, but at the tank's full 1.9 SG rating the contents can reach 1,585 pounds - a 751 pound difference at the same 100 gallons. That is the whole point of the rating: a standard 1.0-SG water tank would only be structured for about 834 pounds of contents, so anyone cross-shopping a cheaper water tank for chemical service is under-rating the structure by roughly 90 percent. Plan your pad, anchoring, and forklift access around the 1,585 pound loaded figure, not the dry shell. The top is configured with a flange, an 18 inch PE threaded and vented fitting, and a manway with 15 inch access for filling, venting, and interior inspection. Confirm the exact thread sizes and outlet placement against the technical drawing on this page before you order valves or plumbing. If you are still settling on capacity, the Tank Sizing Calculator and Tank Sizing Guide walk you through usable volume versus nameplate gallons.
Chemical compatibility
This tank is molded from high density linear polyethylene (HDLPE) and rated to 1.9 specific gravity. Compatibility always depends on concentration and temperature, so verify your exact chemical, strength, and operating temperature against the OEM chemical-resistance chart - the values below are concentration-specific reference points, not a blanket approval. One advantage of the 1.9 rating: every chemical in the list below is covered at this SG, including the heavy hitters like 98% sulfuric acid and ferric chloride, so nothing here forces you to step up to a higher-SG tank.
Chemicals this XLPE tank is suited to store, with the recommended fitting and gasket materials, include acetic acid (60%, PP/PVC fittings, EPDM gaskets), aluminum sulfate (50%, PVC, EPDM), calcium chloride (40%, PVC, EPDM), DEF (32.5%, 316SS fittings, EPDM), ethylene glycol (100%, PVC, EPDM), ferric chloride (50%, PVC, EPDM), ferric sulfate (60%, PVC, EPDM), ferrous sulfate (20%, PVC, EPDM), hydrochloric acid (37%, PVC fittings, Viton gaskets), hydrofluoric acid (48%, PP/PVC, Viton), hydrofluosilicic acid (26%, PP/PVC, Viton), hydrogen peroxide (50%, PVC, Viton), magnesium chloride (30%, PVC, EPDM), peracetic acid (30%, 316SS, Aflas), phosphoric acid (85%, PVC, Viton), polyaluminum chloride (PVC, EPDM), potassium carbonate (50%, PVC, EPDM), potassium hydroxide (saturated, PVC, EPDM), propylene glycol (PP/316SS, EPDM), sodium bisulfate (PVC/PP, EPDM), sodium bisulfite (PVC/PP, EPDM), sodium carbonate (30%, PVC, EPDM), sodium hypochlorite (under 16.5%, PVC, Viton), sodium thiosulfate (40%, PVC, EPDM), sulfuric acid (98%, CPVC fittings, Viton gaskets), urea solution (50%, PP/PVC, EPDM), zinc orthophosphate (PP/316SS, EPDM), and ozonated water (up to 10 PPM, PVC, EPDM - see the general Chemical Compatibility Database for this one).

The mistake to avoid
The most common error on a chemical tank this size is matching the fitting and gasket to the tank instead of to the chemical. The flange and the 18 inch threaded fitting are where you select your wetted hardware - PVC, CPVC, or 316SS bodies with Viton, EPDM, or Aflas gaskets per the table above - and the 15 inch manway is your access point to inspect those gaskets over time. The polyethylene shell handles a wide range, but the gaskets do not: sodium hypochlorite, hydrochloric acid, hydrogen peroxide, and sulfuric acid here call for Viton (Aflas on peracetic acid), while most salts and glycols run on EPDM. Install an EPDM gasket on a hypochlorite or strong-acid line and it will swell and weep while the tank itself looks fine. Match every wetted component to the chemical, and for high-strength sulfuric or hypochlorite service confirm your instrumentation is rated for it too - our guide on tank level gauge selection for chemical service compares radar, ultrasonic, hydrostatic, and magnetostrictive options. If secondary containment is on your spec, the Snyder Captor Plus 110% containment comparison is worth reading before you finalize the layout.
