The Norwesco 50 Gallon Pest Control Operator (PCO) Tank in white is purpose-built for the rig deck: a compact 50-gallon polyethylene tank measuring 23" high by 19" wide by 38" long, molded from Norwesco polyethylene and rated to a 1.5 specific gravity. That SG 1.5 rating is the number that matters most on a PCO unit, because it tells you the tank wall is built to carry contents heavier than water, the working condition for most pest control and lawn-care chemistries you'll mix and haul. If you've been searching for a 50 gallon Norwesco tank or a PCO tank that drops onto a truck or trailer skid, this is the size and shape that fits.
Does it work for your setup?
The footprint is 19.0 x 38.0 inches, so the tank lies long and low rather than tall, which keeps the center of gravity down on a moving vehicle and makes the elongated profile easy to strap into a bed or skid frame. Filled with water, this tank carries roughly 417 lb of contents; at its full 1.5 specific gravity rating it is engineered to hold up to 626 lb of contents. Both figures are contents only — the pack gives no tare weight, so add the empty tank's own weight when you size mounting, pump bracketry, and the rated load of the trailer or truck before you fill. To confirm how 50 gallons of your specific chemistry pencils out against axle and platform limits, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide. Exact wall, fitting, and dimensional detail is on the technical drawing on this page.

Specific gravity: the mistake to avoid
The single most common error on a PCO tank is treating it as a plain water tank. This unit is rated to 1.5 specific gravity, meaning it's intended for liquids up to 1.5 times the density of water. Before you load any pesticide, herbicide, or surfactant blend, confirm your finished mix density stays at or under that 1.5 rating, and verify the chemistry itself against the manufacturer's chemical-resistance data for polyethylene at your concentration and temperature. The white color and 50-gallon body suit a service rig, but the SG rating, not the gallon number, defines what you can safely carry. When in doubt about a heavier blend, call us before you buy.
Freight and ordering
This Norwesco PCO tank ships LTL freight, quoted live to your ZIP from the nearest origin. It ships from Norwesco stock in Georgia (Griffin, GA), Mississippi, and Ohio (Lancaster, OH), so a buyer in the Southeast, Mid-South, or Midwest typically draws the shorter, cheaper lane. Freight is quoted separately from the list price; get your exact number in seconds with our Freight Cost Estimator, or call 866-418-1777 and we'll size the tank, confirm the closest origin, and lock in your freight to ZIP.
