Hunter Industries PRL-25-3F3F Pressure Regulator 25 Psi

Product Description

The HUNTER INDUSTRIES PRL-25-3F3F is a 3/4-inch female iron pipe thread (FIPT) inline pressure regulator designed to maintain a steady 25 psi downstream in irrigation and fluid distribution systems. It handles flow rates from 0.1 to 8 gallons per minute (GPM), making it well suited for drip, micro, and low-volume irrigation zones. Licensed irrigators and field technicians install this regulator upstream of emitters, drip tape, or micro-spray heads to protect equipment from pressure fluctuations that cause uneven distribution or hardware failure. The unit weighs 0.28 pounds, keeping installation straightforward on both new builds and retrofit applications.

This regulator fits residential and light commercial irrigation systems where pressure reduction is needed at the zone or lateral level. It is commonly installed in-line on drip irrigation manifolds, raised-bed watering systems, and low-volume landscape zones. Its 3/4-inch FIPT connections accept standard threaded poly or PVC fittings found throughout irrigation infrastructure. The 0.1 to 8 GPM flow range covers most drip and micro-spray zone demands without requiring additional flow-control components.

Key Features

• Regulated outlet pressure of 25 psi protects downstream drip and micro-irrigation components
• Flow range of 0.1 to 8 GPM accommodates low-volume zone designs
• 3/4-inch FIPT inlet and outlet connections for direct inline installation
• Lightweight at 0.28 pounds for easy handling and installation
• Compact inline form factor fits standard irrigation manifold configurations

Compatibility

Designed as an OEM-style inline pressure regulator for use in 3/4-inch threaded irrigation systems requiring 25 psi zone-level pressure regulation.

Installation Notes

A licensed irrigator or qualified field technician should install this regulator in compliance with local plumbing and irrigation codes. Shut off the water supply and relieve system pressure before making any threaded connections. Use thread-seal tape on all FIPT connections to prevent leaks, and observe the flow-direction arrow on the regulator body to ensure correct orientation. Do not exceed the rated flow range, as operating outside specified GPM limits can reduce regulation accuracy.
