Coilhose Pneumatics 4214-90PS Inline Air Regulator 150 Psi

Product Description

The COILHOSE PNEUMATICS 4214-90PS is an inline air pressure regulator designed to control and maintain downstream air pressure in compressed air systems. Built with 0.25 inch NPT end connections, it handles a maximum inlet pressure of 150 psi and fits directly into existing pneumatic lines without special adapters. At 0.2 pounds, this compact regulator is well suited for tool stations, machinery drops, and point-of-use pressure control applications. Licensed service technicians and industrial maintenance professionals install this type of regulator when consistent, regulated air pressure is required at a specific point in a pneumatic circuit.

The 4214-90PS is part of the COILHOSE PNEUMATICS Series 4214 inline regulator lineup. It is appropriate for light-duty to medium-duty compressed air applications in manufacturing, automotive service, construction, and general industrial environments. The 0.25 inch NPT port size makes it compatible with standard pneumatic fittings and airline assemblies commonly found in shop and field installations. Typical installation locations include compressor outlet drops, tool feed lines, and pneumatic control circuits requiring localized pressure adjustment.

Key Features

• 150 psi maximum working pressure for broad compressed air system compatibility
• 0.25 inch NPT end connections for direct integration with standard pneumatic fittings
• Inline design allows installation without redesigning existing airline layouts
• Lightweight at 0.2 pounds for easy mounting in space-limited locations
• Series 4214 construction for consistent pressure regulation at the point of use

Compatibility

Designed as an OEM-style inline replacement regulator for 0.25 inch NPT compressed air systems and pneumatic tool feed lines.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician or industrial maintenance professional. Depressurize and lock out the compressed air supply before removing or installing any inline regulator. Verify that thread sealant is applied to all NPT connections per standard practice to prevent air leaks. Do not exceed the 150 psi maximum rated inlet pressure.
