Coilhose Pneumatics 27R4 Air Regulator 1/2 Npt 250 Psi

Product Description

The COILHOSE PNEUMATICS 27R4 is a standard compressed air regulator designed to control and maintain downstream air pressure in pneumatic systems. Built from cast aluminum, it accepts a 1/2-inch NPT inlet and outlet connection and handles a maximum supply pressure of 250 psi. The regulated output range runs from 0 to 125 psi, making it well suited for a wide range of pneumatic tools and equipment. A 1/4-inch gauge port is included for adding a pressure gauge if monitoring is required. Licensed pipefitters, mechanical contractors, and industrial maintenance technicians are the primary installers for this type of regulator.

The 27R4 is intended for compressed air service in both commercial and industrial applications where downstream pressure must be stepped down and held steady. It supports a maximum air flow of 120 CFM, which makes it appropriate for moderate- to high-demand pneumatic circuits. The modular connection design allows it to be integrated into filter-regulator-lubricator assemblies within the Series 27 product line. Typical install locations include compressor drop legs, tool stations, and machine air preparation panels.

Key Features

• 1/2-inch NPT end connections for straightforward pipe or hose integration
• 0 to 125 psi adjustable output range with 250 psi maximum supply pressure
• 120 CFM maximum air flow capacity for moderate- to high-demand circuits
• Cast aluminum body for lightweight durability in industrial environments
• Built-in relief function to vent excess downstream pressure automatically
• Modular connection compatible with Series 27 filter and lubricator components
• 1/4-inch gauge port for optional downstream pressure gauge installation

Compatibility

Designed for use with compressed air systems and compatible with COILHOSE PNEUMATICS Series 27 modular air preparation components.

Installation Notes

Installation should be performed by a qualified pipefitter or pneumatic systems technician. Depressurize and isolate the air supply fully before removing any existing regulator or fittings. Apply appropriate thread sealant to NPT connections per shop practice and local codes. Do not exceed the 250 psi maximum supply pressure rating under any operating condition.
