The Rain Bird PFRFRA PolyFlex Riser & Adapter Assembly is a rugged, pre-assembled riser designed for low-volume Xerigation systems. Built from thick-walled, high-density polyethylene with a heavy-duty Marlex adapter, this riser raises drip and micro-spray emitters above the plant canopy for targeted watering and reliable performance.

  • Pre-assembled 12" riser: Ready to install with a 1/2" male threaded (MPT) base to simplify connection to laterals and fittings.
  • Emitter compatibility: Accepts any 10-32 threaded emission device, including Xeri-Bugs, PC Modules, Xeri-Bubblers and Xeri-Sprays, for flexible design options.
  • Durable materials: Thick-walled polyethylene riser with a Marlex adapter that eliminates the need for Teflon tape and resists field stresses.
  • Fast installation: Larger adapter tabs make insertion and removal quicker when used on PVC laterals or with 1/2" female threaded adapters.
  • Designed for irrigation pressures: Suitable for typical low-volume system pressures (manufacturer guidance: 15–50 psi).

Ideal for landscape professionals and homeowners installing Xerigation or drip systems, the PFRFRA riser reduces installation time while delivering precise water placement at the root zone. Pair with compatible Rain Bird emitters to tailor flow and coverage for shrubs, groundcovers, and specimen plants.
