Coilhose Pneumatics 4012G Inline Air Regulator 150 Psi

Product Description

The COILHOSE PNEUMATICS 4012G is an inline pneumatic pressure regulator designed to control and maintain downstream air pressure in compressed air systems. With a 1-1/2 inch NPT port and a maximum operating pressure of 150 psi, it is built for medium-to-large diameter air lines where precise pressure regulation is required. The 4012G installs directly in-line with the compressed air supply and is sized for industrial and commercial pneumatic systems. Licensed HVAC technicians, plumbers, and industrial maintenance professionals install this type of regulator as part of compressed air distribution networks to protect downstream equipment from pressure spikes.

The 4012G is suited for compressed air systems in industrial facilities, manufacturing environments, and large commercial mechanical rooms where 1-1/2 inch NPT connections are standard. It regulates supply pressure to tools, pneumatic actuators, and air-driven equipment. The NPT end connections make it compatible with standard threaded iron or steel pipe fittings commonly found in established compressed air distribution systems.

Key Features

• 1-1/2 inch NPT port for direct inline installation on standard threaded pipe
• 150 psi maximum pressure rating suitable for industrial compressed air applications
• Inline design allows installation anywhere along the air supply line
• Lightweight construction at 0.3 pounds for easy handling and installation
• NPT end connections ensure compatibility with standard threaded fittings

Compatibility

Designed as an OEM-style inline regulator for compressed air systems using 1-1/2 inch NPT threaded connections at pressures up to 150 psi.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed air system pipework. Depressurize and isolate the air supply line completely before installing or removing this regulator. Apply thread sealant tape or compound to NPT threads per manufacturer and applicable codes before tightening. Do not exceed the 150 psi maximum rated inlet pressure during operation or testing.
