The Snyder Industries 17 Gallon Heavy Duty Cone Bottom Mixing Tank is a small-footprint cone bottom built for chemical mixing and full-drain batch work. It holds 17 gallons in a 19 x 19 inch footprint and stands 24 inches tall, molded in black High Density Linear Polyethylene with a 1.9 specific gravity rating. That 1.9 SG rating is the headline spec for a chemical tank this size, and it is the highest density rating offered in this cone style and size: it means the wall is engineered for dense liquids, not just water, so heavy concentrated solutions are within its design envelope rather than pushing it past spec. This is the ceiling, not a mid-tier option.
Will it work for your job?
This is a cone bottom mixing tank, so the angled floor drains completely and keeps solids in suspension from settling out at the base, which is exactly what you want for blended chemistry. Empty water fill weighs about 142 lb, and at its 1.9 SG rating the tank carries up to roughly 269 lb of contents, so size the stand and floor for the dense-liquid case, not the water number. The vessel itself is compact and light, but a fully loaded tank of heavy chemistry is not, so the stand and anchoring matter. The tank ships bare with no factory fittings or bulkheads pre-installed, so fittings and gaskets are selected and ordered separately per the compatibility table below. For matching this tank to a stand, see the cone bottom tank stand compatibility matrix, and use the Tank Sizing Calculator and Tank Sizing Guide to confirm the volume fits your batch. Dimensions and fitting locations are shown on the technical drawing on this page.
Chemical compatibility
This tank is molded in HDLPE and rated to 1.9 specific gravity, which covers the dense acids and concentrated solutions below. Compatibility is concentration- and temperature-specific, so always confirm your exact chemical, strength, and operating temperature against the OEM chemical-resistance chart before service. Fitting and gasket materials below are the recommended pairing for each chemical; the tank wall handling a chemical does not mean a standard fitting will. Common services this tank suits include sulfuric acid at 98% (CPVC fittings, Viton gaskets), hydrochloric acid at 37% (PVC, Viton), phosphoric acid at 85% (PVC, Viton), ferric chloride at 50% (PVC, EPDM), aluminum sulfate at 50% (PVC, EPDM), sodium hypochlorite below 16.5% (PVC, Viton), hydrogen peroxide at 50% (PVC, Viton), and concentrated bases like potassium hydroxide (saturated, PVC, EPDM) and sodium carbonate at 30% (PVC, EPDM). It also handles hydrofluoric acid at 48% (PP/PVC fittings, Viton gasket), glycols including ethylene glycol and propylene glycol, ozonated water up to 10 PPM (PVC, EPDM), and a range of metal-salt and sulfate solutions. Aggressive oxidizers and acids like hypochlorite, peroxide, sulfuric, phosphoric, and the hydrofluoric group require Viton or Aflas gaskets rather than EPDM, so match the seal to the chemical. A separate point on fittings: most services here run on PVC or CPVC, but DEF at 32.5%, peracetic acid at 30% (Aflas gasket), and zinc orthophosphate call for 316 stainless or PP fittings, not PVC, so step the fitting metallurgy up for those. Full per-chemical detail lives in the Chemical Compatibility Database.
The mistake to avoid
The error on a tank like this is reading the 1.9 SG rating as a green light for any chemical at the water-weight number. Two things bite people: first, plan around the loaded weight (up to about 269 lb of contents), not the 142 lb water fill; second, the tank wall is only half the job. A chemical the HDLPE shell tolerates can still destroy the wrong fitting or gasket, which is why the table above pairs each chemical with a specific fitting and gasket material. This tank also ships as a bare mixing vessel, so secondary containment is your responsibility and is not built in. For chemical service, confirm your exact concentration and temperature against the OEM chart, and for blended batches review the fertilizer-blend tank stratification guide on keeping dense blends from salting out. For level monitoring on chemical duty, the tank level gauge selection guide walks through radar, ultrasonic, hydrostatic, and magnetostrictive options. If your application calls for built-in containment, the Snyder Captor Plus 110% containment vs UL-142 comparison covers double-wall options that include it.
