Hunter Dripline HDL-CV, HDL-PC, HDL-R


  • Flow: 1.5, 2.1, 3.4 l/hr
  • Surface or Subsurface Irrigation: Gardens, Turf, Tree Rings, Green Walls, Irregular Spaces


Hunter Dripline (HDL) is a high-efficiency, ultra-durable upgrade to PLD that is available in three pressure-compensating varieties to accommodate a range of drip system needs. Choose HDL-PC for standard installations, HDL-CV for sloping or subsurface applications that require a check valve, and HDL-R when using reclaimed water.

Install HDL at grade or subsurface to effectively and precisely irrigate shrubs, gardens, turf, perennials, and trees. Kink- and UV-resistant HDL features a large internal diameter that allows fittings to be installed more easily, and provides the capacity for longer maximum runs. Highly consistent pressure-compensating emitters come with a built-in filter inlet port as well as wide labyrinth pathways to prevent clogging.

Color-coded striping allows users to quickly identify the flow in the field, saving time during maintenance. Tan, gray, and black colors indicate flow rates of 1.5, 2.1, and 3.4 l/hr, respectively. Purple indicates non-potable applications. The dripline can be easily unraveled from the inside of the coil since it is stretch-wrapped, keeping the coil intact.

In addition, the eco-friendly HDL is made with approximately 80% pre-consumer reprocessed resins, offering a high level of sustainability without sacrificing quality.

Key Benefits

  • Pressure-compensating emitters for consistent flow and uniform coverage
  • Colour-coded stripes provide easy identification of flow
  • UV resistance facilitates product longevity
  • Stretch-wrapped coils stay intact and make installation quick and easy
  • Superior grit tolerance provided by proprietary emitter design with multiple inlet filters, a wide turbulent labyrinth, and a full-size outlet pool
  • Reclaimed product (HDL-R) identified by purple stripes assists in visual identification when using non-potable water
  • Pressure-compensating emitters for consistent flow and uniform coverage
  • Non-draining check valve(CV-ND) prevents low-point pooling and allows all emitters to open/close at the same time for greater system efficiency
  • Anti-siphon feature prevents debris from entering emitter at system shutdown
  • Slow-draining check valve (CV) emitters prevent low-point pooling and add to system efficiency
  • Multiple inlet filters in the emitter and a wide turbulent labyrinth provide superior grit tolerance
  • Full-sized emitter outlet pool and raised wall inhibit debris and roots from entering the emitter
