Pressure Compensating Emitters (PC Emitters, or Drippers) deliver a consistent flow rate regardless of changes in pressure due to elevation changes.  Pressure compensating emitters are the right choice for situations requiring precise water flow for each emitter or plant.  These emitters are available with either 1/4″ barb fittings or self-piercing for easy installation into Drip Distribution lines. Place bug guard at end to prevent bugs and debris from clogging tubing.
