The Snyder Industries 50 Gallon Industrial HDLPE Rectangular PCO Tank is a 1.5 specific-gravity portable chemical tank built for batch dosing, transfer, and point-of-use storage where floor space is tight. At 38 inches long, 20 inches wide, and 22 inches tall, this rectangular tank sits low with a compact 20.0 x 38.0 inch footprint, so it fits under benches, on skid platforms, and inside spill pallets that a round 50-gallon tank would overhang. The white polyethylene wall lets operators read the liquid level at a glance.
Will it work for your application?
This is a Snyder Industries rectangular PCO tank rated to 1.5 specific gravity, meaning the wall carries contents up to 1.5 times the density of water. Empty it holds 50 gallons; filled with water it weighs about 417 pounds, and at its full 1.5 SG rating it is engineered to support up to 626 pounds of contents. That distinction matters: a true 1.5 SG chemical such as 50% aluminum sulfate or 40% calcium chloride loads your stand to roughly 626 pounds plus tank weight, far more than the 417-pound water figure most people anchor on. Rate the stand, skid, or shelf to the 626-pound contents load plus tank weight before you fill. One caution on this SKU: the installed fitting and port configuration is not listed in our specs, so call 866-418-1777 to confirm outlets, bulkhead, vent, and lid before ordering, and see the technical drawing on this page for wall and port detail. Run your numbers through the Tank Sizing Calculator or the Tank Sizing Guide when matching this 50 gallon tank to a target volume and dosing rate.
Chemical compatibility
This tank is molded in HDLPE and carries a 1.5 specific-gravity rating. The resin designation ends with a question mark in our records, so confirm via the part number with Snyder or our team whether your unit is HDLPE before committing it to chemical service. The entire compatibility table below assumes HDLPE; if the unit is a different polyethylene resin the table does not apply. The resin grade determines the chemical resistance profile, and that single check prevents the most expensive mistake on a tank like this. At the 1.5 SG rating, this tank suits the following chemicals at the concentrations shown, with the wetted fitting and gasket materials each one requires:
- Acetic Acid at 60% - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate at 50% - PVC fittings, EPDM gaskets
- Calcium Chloride at 40% - PVC fittings, EPDM gaskets
- DEF (diesel exhaust fluid) at 32.5% - 316SS fittings, EPDM gaskets
- Ferrous Sulfate at 20% - PVC fittings, EPDM gaskets
- Magnesium Chloride at 30% - PVC fittings, EPDM gaskets
- Sodium Carbonate at 30% - PVC fittings, EPDM gaskets
- Urea Solution at 50% - PP/PVC fittings, EPDM gaskets
- Ozonated Water up to 10 PPM - PVC fittings, EPDM gaskets
These are wetted-component specs you source separately: the tank ships without fittings and gaskets, and the gasket and fitting material must match the chemical, not the tank. DEF, for instance, needs 316SS fittings with EPDM gaskets. Verify every selection against the OEM chemical-resistance chart for your exact concentration and operating temperature, and use our Chemical Compatibility Database for the per-chemical detail.
Storing a denser chemical? You need the 1.9 SG version, not this one
Several chemicals exceed what a 1.5 SG tank is rated to carry and require a higher 1.9 SG tank instead. If your application involves any of these, step up rather than running this tank out of spec: Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrochloric Acid, Hydrofluoric Acid, Hydrofluosilicic Acid, Hydrogen Peroxide, Peracetic Acid, Phosphoric Acid, Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Hypochlorite, Sodium Thiosulfate, Sulfuric Acid, and Zinc Orthophosphate. Several of these also carry distinct sealing demands worth planning early: Sulfuric Acid needs CPVC fittings with Viton gaskets, Peracetic Acid needs 316SS with Aflas, and Hydrochloric Acid, Hydrofluoric Acid, Hydrogen Peroxide, and Sodium Hypochlorite all call for Viton in place of EPDM. Storing any of these means the 1.9 SG version of this tank, not this 1.5 SG unit.
Plan fittings and dosing before you order
On a rectangular PCO tank, top-fitting placement drives whether your vent, fill, level, and drain lines stay out of each other's way. Our guide on tank top fitting placement strategy walks through that layout, and our tank level gauge selection guide covers reading level in chemical service. If this tank stores a hazardous chemical, our tank labeling and signage compliance guide covers NFPA 704, GHS, and DOT marking.
