The Rain Bird PA8S plastic shrub adapter connects Rain Bird spray and rotary nozzles to 1/2" (15/21) MPT threaded risers so you can irrigate groundcover and shrub areas with reliable, maintenance‑friendly performance. Built in durable, non‑corrosive thermoplastic, the PA8S is designed for long outdoor service and to accept common nozzle filters for cleaner operation.

  • Adapts Rain Bird nozzles for use with 1/2" (15/21) NPT/MPT threaded risers for standard shrub and groundcover installations.
  • Durable, non‑corrosive plastic construction resists UV and outdoor exposure for dependable season-after-season use.
  • Fine top threads accept all Rain Bird nozzles, ensuring broad compatibility across the Rain Bird nozzle lineup.
  • Accepts protective, non-clogging 1800 Series filter screens (shipped with many Rain Bird nozzles) and PCS Series screens to help prevent debris from blocking spray patterns.
  • Simple installation—threads into the riser and receives the nozzle; compatible nozzle sold separately for customizable spray performance.

Choose the PA8S when you need a low-cost, reliable adapter to mount Rain Bird nozzles on risers for beds, hedges, and shrub borders. The PA8S is sold as the Rain Bird model PA8S (store SKU A16501A on Rain Bird's site) and pairs with standard Rain Bird nozzles and screens; check nozzle selection for desired radius and arc. For non-potable systems, Rain Bird also offers a dedicated purple PA-8S-NP non-potable model—confirm model code if required. If you need pressure regulation, see Rain Bird PRS variants that include an internal regulator.
