Ritchie Engineering 67044 Vacuum Sensor G3 Replacement

Product Description

The RITCHIE ENGINEERING 67044 is a replacement vacuum sensor designed for use with the Yellow Jacket G3 vacuum gauge system. This sensor measures system vacuum levels and feeds readings to the G3 digital vacuum gauge, giving HVAC technicians an accurate, real-time view of system evacuation status. It is a direct OEM-style replacement for field-worn or damaged G3 sensors, restoring the gauge system to full function without requiring a complete unit swap. Licensed HVAC technicians performing system evacuation and commissioning work will find this sensor a straightforward drop-in service part.

This sensor is used during refrigerant system evacuation procedures in residential and light commercial HVAC applications. It connects to the Yellow Jacket G3 vacuum gauge and is positioned on the system being evacuated to monitor micron levels throughout the pulldown process. Accurate vacuum measurement is a code-supported best practice before refrigerant charge is introduced, making a functioning sensor essential to any proper evacuation workflow.

Key Features

• Direct replacement sensor for the Yellow Jacket G3 vacuum gauge system
• Restores full vacuum measurement functionality without replacing the entire gauge unit
• Manufactured in the United States
• OEM-equivalent design for reliable performance in field evacuation work

Compatibility

Designed as a replacement sensor for the Yellow Jacket G3 vacuum gauge system. Consult your G3 gauge documentation to confirm sensor compatibility before installation.

Installation Notes

Installation of this sensor should be performed by a licensed HVAC technician familiar with refrigerant system evacuation procedures. Before replacing the sensor, ensure the vacuum gauge is disconnected from any active vacuum source and that system pressure is at a safe level. Handle sensor connections carefully to avoid contamination or damage to the sensing element. Refer to the Yellow Jacket G3 gauge documentation for sensor connection and calibration procedures.
