Rain Bird PSI-M25 Pressure Regulator 3/4″ F (In: 1.5-7 bar / Out: 1.8 bar)

Protect your drip irrigation system from high water pressure and ensure spot-on performance from every single emitter with this reliable pressure regulator from industry leaders, Rain Bird.

The genuine Rain Bird PSI-M25 pressure limiter is a trade-quality bit of kit designed specifically for micro-irrigation systems, leaky pipes, and drip lines. Its main job is to take high or fluctuating mains water pressure and drop it down to a steady, safe 1.8 bar (25 PSI). By regulating the pressure, you stop compression fittings popping off, prevent pipe bursts, and ensure that every plant gets the exact same amount of water from the first nozzle to the last.

Key Features & Benefits:

• Trusted Rain Bird Quality: Factory-calibrated and rigorously tested by the biggest name in irrigation for total peace of mind and years of reliable service.
• Precise 1.8 Bar Regulation: Maintains a constant outlet pressure, preventing misting or fogging from micro-sprays, which cuts down on water wastage caused by wind drift.
• Handles Tough Mains Pressure: Safely tames high incoming pressure anywhere between 1.5 and 7.0 bar.
• Heavy-Duty Build: Moulded from high-grade, UV-resistant engineering plastic to withstand harsh British weather, water hammer, and garden chemicals.
• Straightforward Installation: Features standard 3/4″ Female BSP threads (3/4″ F) on the inlet, making it a breeze to connect directly to garden taps, valve boxes, or inline filters.

Typical Applications:

The Rain Bird PSI-M25 is an essential component at the start of any low-volume irrigation zone. It is fully compatible with professional drip lines (such as Rain Bird XFD), porous soaker hoses, and micro-sprinkler setups in domestic gardens, allotments, raised beds, and commercial greenhouses.
