Pail/Jug Mount Uni-Body W-20 Spray-All

Model # 975018

The Pail/Jug Mount Uni-Body W-20 Spray-All is a convenient container-mounted, low-volume spray applicator. This venturi injection system uses standard city water pressure (35 - 125 PSI) to draw chemical concentrate directly from the container and blend it into the water stream. Precision metering tips create an accurately diluted solution which is projected through the discharge hose and fan nozzle as a light, uniform spray. With a flow rate of just under 1 gallon per minute, this unit is great for spraying virtually any size area or object, slowly and completely, with very little run-off.

Key Features 

  • Screws onto, and dispenses directly from, chemical concentrate containers for increased efficiency
  • Creates a low volume spray (under 1 GPM @ 40 PSI)
  • Ideal for precision application in small areas and near sensitive equipment where minimal over-spray is crucial
  • Fan pattern nozzle for even coverage
  • Chemical resistant wetted components ensure outstanding performance with minimal maintenance - machined, not molded!
  • Use it anywhere 35-125 PSI water is available
  • Easy to set up - no tools or mounting hardware required
  • Fits 1-gallon jugs, pull-up spouts on 5-gallon pails, or any container with 38mm OD threads
