The Snyder Industries 300 Gallon 45 Degree Cone Bottom Viscous Liquid Hopper Tank (SKU SII-6370541N95402) is a closed-top cone bottom tank on a matching poly stand, built for complete drainage of thick, settling, or high-solids liquids. The steep 45-degree cone empties fully by gravity, and the 1.5 specific gravity rating means this tank is engineered for chemical service, not just water. It stands 68" tall on a 45" x 50" footprint, holds 300 gallons, carries a 12" lid, and is certified to standards 2285 and 2282. It ships from Snyder's plant in Lincoln, Nebraska. If you are cross-shopping, this is the tank people find searching "300 gallon" viscous liquid cone bottom with stand.
Will it handle your liquid
The tank body is High Density Linear Polyethylene rated to a 1.5 specific gravity and a maximum temperature of 120 F (48 C), with a 12" lid for filling and access and a 45-degree cone for viscous-liquid drainout. Empty it weighs 385 lb. Plan your stand and pad around full-load weight, not empty: 300 gallons of water is roughly 2,502 lb, and at the full 1.5 SG rating the contents can reach about 3,753 lb. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm the load your floor and stand legs need to carry before you order. Refer to the technical drawing on this page for the exact cone, lid, and stand geometry.
Chemical compatibility
This is an HDLPE tank rated to 1.5 specific gravity, matched here against the Snyder Industries OEM chemical resistance chart. That chart is concentration- and temperature-specific, so confirm your exact chemical, concentration, temperature, and fitting and gasket materials before service. At the 1.5 SG rating, this tank suits Acetic Acid (60%), Aluminum Sulfate (50%), Calcium Chloride (40%), DEF (32.5%), Ferrous Sulfate (20%), Magnesium Chloride (30%), Sodium Carbonate (30%), Urea Solution (50%), and Ozonated Water (up to 10 PPM). Most of these pair with PVC or PP fittings and EPDM gaskets; Urea takes PP/PVC with EPDM, Ozonated Water takes PVC/EPDM, and DEF is the outlier that calls for 316SS fittings with EPDM. Verify each against the OEM chart and the Chemical Compatibility Database.
The mistake to avoid
Do not push this 1.5 SG tank into heavier-density service. Chemicals such as Sulfuric Acid (98%, CPVC fittings and Viton gaskets), Ferric Chloride (50%), Hydrochloric Acid (37%), Hydrogen Peroxide (50%), Phosphoric Acid (85%), and Sodium Hypochlorite (<16.5%) all require Viton gaskets, and Peracetic Acid (30%) needs 316SS fittings with Aflas. Every one of these requires a higher 1.9 specific gravity tank, not this one. For those chemicals, step up to a 1.9 SG cone bottom tank rather than ordering this model, which is the most common and costliest error on a hopper this size. Check your chemical in the Chemical Compatibility Database or call us to match the right resin and SG. For sizing background, see our 300 Gallon cone bottom buyer's guide.
