Orifice Diffuser (Small: 3/4" - 1" Pipe)

Part Number

Polylok’s orifice diffuser offers advancements in effluent distribution you will not see in other pressure dosing systems. Our patented design includes an impeller that directs wastewater from the discharge piping in a 360º manner. This optimizes the leaching fields and protects the soils around the piping from unnecessary erosion.


  • Fits securely onto either ¾”-1” pipe or 1¼”-2” pipe
  • Constructed of engineered resin
  • Provides a tight fit which prevents slippage once installed
  • Slotted design prevents plugging of discharge openings with surrounding soil
  • Can be installed with discharge openings facing up or down
  • 360º equal flow distribution with impeller

Our orifice diffusers accomodate two sizes:

  • 3081 (¾” - 1” pipe)
  • 3080 (1¼” - 2” pipe)
