Thread In 3/8 x 24 Fitting with Metric Port for GM Sensor

LS Swap GM A/C Pressure Sensor Thread-In Fitting – Brass

Maintain factory-level driveability in your LS-swapped vehicle by integrating the GM A/C pressure sensor directly into your high-side line. This high-quality brass thread-in fitting allows your ECM or PCM to monitor system pressure, enabling the computer to bump the idle and trigger cooling fans automatically when the A/C is in use.

Integrating this sensor is the most effective way to prevent the common “RPM dip” or stalling that occurs when the A/C compressor engages at a stoplight, ensuring your swap drives like a factory-built vehicle.

Technical Specifications

• Material: Premium Brass for superior corrosion resistance and a leak-free seal.

• Installation Type: Thread-in (Designed for easy installation into existing high-side ports).

• System Location: High-Pressure (Discharge) side only.

• Sensor Side Thread Pitch: M10x1.25 (Specifically threaded for the GM A/C Pressure Sensor).

• Line Side Thread Pitch: 3/8×24 (Specifically threaded for the GM A/C Pressure Sensor).

• Function: Provides the ECM with the necessary data for idle compensation and fan pulse-width modulation (PWM) or relay control.

Installation Note

This fitting is intended for use on the High Side of your A/C system. For proper operation, the GM sensor must be able to read the discharge pressure to tell the ECM when to increase fan speeds to keep head pressures in check.
