Drum Bung Mount Uni-Body W-20 Spray-All

The Drum Bung Mount Uni-Body™ W-20 Spray-All has threads to fit most bung openings, and is a water-driven, low volume sprayer that mixes chemical with water and projects the solution as a light, uniform spray. This venturi injection system uses standard city water pressure (35 – 125 PSI) to draw chemical concentrate directly from the drum into the water stream. Precision metering tips control chemical volume to create an accurately diluted solution that is projected through the discharge hose and fan nozzle. With a flow rate of just under 1 gallon per minute, this unit produces very little runoff with slow, precise coverage of virtually any size area or object.
