The Snyder Industries 200 Gallon Plastic Vertical Chemical Storage Tank in White is a 1.9 specific-gravity polyethylene vertical tank built for dense liquid-chemical service, not just water. It stands 42 inches tall on a 40 by 40 inch footprint and holds 200 gallons, keeping it compact for indoor process bays and skid mounts. The 1.9 SG rating is the number that matters here: it means the tank wall is engineered to carry liquids heavier than water, the duty a 1.0 or 1.5 water-rated tank is not built for.
Will it work for your liquid?
Full of plain water, this tank carries about 1,668 pounds. Because the wall is rated to 1.9 SG, the maximum rated contents weight is roughly 3,169 pounds, which is what lets you store dense chemicals such as concentrated acids, brines, and glycols. Size your liquid against that 3,169-pound ceiling, not the water figure, and confirm your pump, secondary containment, and pad are rated for the loaded weight. The Tank Sizing Calculator and our Tank Sizing Guide walk through that math. This is the tank people are after when they search for a 200 gallon vertical storage tank, and the 42-inch height keeps it manageable for indoor bays and skid mounts.
Chemical compatibility
This tank is polyethylene with a 1.9 specific-gravity rating. The resin is listed as HDLPE but flagged unverified, so confirm HDLPE versus XLPE for your specific service before committing the tank to chemical duty. On fittings, most liquids below run PVC; DEF and peracetic acid require 316 stainless (propylene glycol and zinc orthophosphate accept PP or 316SS); and 98% sulfuric acid requires CPVC. On gaskets, EPDM is the default, Viton is required for hydrochloric, hydrofluoric, hydrofluosilicic, hydrogen peroxide, phosphoric, sodium hypochlorite, and sulfuric acid, and Aflas is a one-off needed only for peracetic acid. The chemicals below come from our Chemical Compatibility Database and are concentration- and temperature-specific, so cross-check your actual operating concentration and temperature before ordering fittings or gaskets:
- 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, database page pending) - PVC fittings, EPDM gaskets
Two of these are concentration ceilings, not typical operating points: sodium hypochlorite is rated to under 16.5% and ozonated water to 10 PPM, and exceeding either voids the compatibility. Match the fitting and gasket material to your chemical exactly, browse the full Chemical Compatibility Database for any liquid not listed here, and never assume a chemical is safe because a similar one is.
The mistake to avoid
The most expensive error on a dense-chemical tank is undersizing the SG rating or mismatching the gasket. This tank's 1.9 rating exists for dense liquids like 98% sulfuric or 50% ferric chloride - storing those in a water-rated 1.0 or 1.5 tank is the wrong tool for the duty. The second mistake is reusing EPDM gaskets on a chemical that calls for Viton or Aflas; a single wrong gasket leaks the very chemical you bought the tank to contain. If you are adding level monitoring, our guide on selecting a tank level gauge for chemical service compares radar, ultrasonic, hydrostatic, and magnetostrictive options for aggressive liquids.
