Netafim WPC20 Techflow 2.0 GPH pressure-compensating dripper engineered to deliver consistent, reliable watering for pots, planters, hanging baskets and subsurface drip installations. The Techflow internal design regulates flow and provides continuous self-cleaning action during operation.

  • Flow rate: 2.0 GPH (color-coded green)
  • Pressure compensation: consistent output from 14.5 to 58 PSI
  • Internal check valve: holds back low-emitter drainage and prevents siphoning
  • Recommended filtration: 120 mesh minimum
  • Connections: inlet 0.160"–0.170" barb; outlet 0.160"

Designed for reliable point-source irrigation, the WPC20 installs quickly with a standard punch tool and works with 0.160"–0.220" micro-tubing. Suitable for surface or subsurface use and compatible with Techline dripperline without causing dripperline drainage. For additional details, refer to the manufacturer Point Source Emitters brochure.
