Rain Bird PA-8S-PRS — 30 PSI Pressure Regulating Shrub Adapter
The Rain Bird PA-8S-PRS threads onto a 1/2" female NPT riser and accepts any Rain Bird plastic nozzle, so shrub and groundcover zones can run at a steady 30 psi without a separate regulator. The body is black thermoplastic for potable irrigation laterals. This page is a single PA-8S-PRS.

Where It Installs
Use the PA-8S-PRS on a 1/2" threaded riser in a shrub or groundcover zone. The built-in PRS stem holds 30 psi at the nozzle so spray nozzles stay in their published pattern instead of misting when the lateral pressure is high. If a nozzle is removed or damaged, the regulator restricts flow. It fits Rain Bird plastic nozzles. It does not include a nozzle.
Frequently Asked Questions
What is the Rain Bird PA-8S-PRS?
It is a pressure-regulating shrub adapter. The 1/2" female inlet screws onto a riser, and the fine top threads take a Rain Bird nozzle. Outlet pressure is held at 30 psi.
Does the PA-8S-PRS include a nozzle?
No. Order the nozzle separately. The adapter accepts Rain Bird plastic nozzles used on 1800 Series spray heads.
What pressure and flow does the PA-8S-PRS handle?
Inlet pressure is 15–70 psi. The stem holds about 30 psi at the nozzle across a flow of 0.2–4.0 GPM.
Is the PA-8S-PRS for non-potable water?
The black PA-8S-PRS is the potable model. For reclaimed water, use the purple PA-8S-PRS-NP.
