Rain Bird's PolyFlex Riser and Stake Assembly provides a simple, durable way to position low-volume irrigation emitters at the plant or root zone. The preassembled 12-inch riser with a 7-inch stake elevates micro-emitters for more even coverage and easier maintenance.

  • Preassembled 12" PolyFlex riser with 7" stake for reliable support.
  • Accepts any 10-32 threaded micro-emitters, including Xeri-Bug, Xeri-Bubbler, Xeri-Spray, and PC Modules.
  • Thick-walled, UV-resistant high-density polyethylene (HDPE) construction for long life in outdoor conditions.
  • 1/4" barbed outlet allows secure connection to 1/4" distribution tubing; riser can be trimmed to desired height.
  • Operates across a 15-50 psi (1.0-3.5 bar) range - ideal for drip and micro-irrigation systems.

Easy to install and service, the PolyFlex riser and stake assembly saves installation time and helps deliver water precisely where plants need it. Use with pressure-compensating or non-pressure-compensating micro-emitters for flexible landscape and container applications.
