R744 manifold gauge set
An R744 (CO₂) manifold gauge set is a high-pressure tool designed specifically for servicing, diagnosing and charging co2 Refrigeration and aircon systems. Featuring durable brass bodies and specialized high-pressure hoses, they are used to handle the extreme pressures (up to 2900 PSI) of R744
Key uses and applications include:
- HVAC/R System Maintenance: Servicing CO₂ racks, commercial refrigeration, and heat pumps.
- Automotive AC Repair: Specifically for luxury vehicles using high-pressure CO₂ systems (e.g., Mercedes-Benz, Maybach).
- Pressure Testing and Charging: The gauges are designed to accurately measure both high and low sides in
systems
Key Features:
- High Pressure Resistance: Equipped with steel-braided hoses and specialized gauges (often 0–1400 PSI low side, 0–2400+ PSI high side)
- Safety: Built with robust materials to withstand the high-pressure nature of CO2
