Hunter Industries PRLG-25-3FH-3MH Pressure Regulator 25 Psi

Product Description

The HUNTER INDUSTRIES PRLG-25-3FH-3MH is a inline pressure regulator designed to maintain a steady downstream pressure of 25 psi across a flow range of 0.1 to 7 gallons per minute. The unit uses 3/4-inch female hose thread (FHT) inlet and 3/4-inch male hose thread (MHT) outlet connections, making it a straightforward inline installation with no adapters required in standard hose-thread applications. Irrigation technicians and landscape contractors install this regulator to protect drip emitters, micro-sprinklers, and low-pressure distribution lines from pressure fluctuations that can cause system damage or uneven application rates.

This regulator is suited for residential and light commercial drip irrigation and micro-irrigation systems where supply pressure regularly exceeds the rated operating range of the downstream components. Typical installations include direct connection to a hose bib or zone valve outlet feeding a drip line assembly. The FHT x MHT configuration allows direct inline placement without additional fittings in most standard hose-thread irrigation layouts.

Key Features

• Regulated outlet pressure of 25 psi for drip and micro-irrigation system protection
• Operating flow range of 0.1 to 7 gpm covers a wide range of low-volume irrigation zones
• 3/4-inch FHT inlet and 3/4-inch MHT outlet for tool-free hand-tight installation
• Compact and lightweight at 0.18 pounds for easy field handling and storage
• Inline design installs directly between supply source and distribution line

Compatibility

Designed as an OEM-style inline pressure regulator for 3/4-inch hose-thread drip and micro-irrigation assemblies where a 25 psi regulated outlet pressure is required.

Installation Notes

Installation is performed by qualified irrigation technicians or licensed plumbers. Shut off the water supply at the zone valve or main before making any connections. Hand-tighten the FHT connection and use a wrench only on the MHT outlet side as needed to prevent overtightening the inlet threads. Verify downstream system pressure rating before pressurizing the zone to confirm the 25 psi outlet is within the acceptable range for all connected components.
