R744 Gauge Set

The R744 Gauge Set is purpose-built for R744 (carbon dioxide, CO₂) natural refrigerant systems, pairing a dedicated gauge set with a dedicated hose and quick coupler — each component specifically engineered to handle the high operating pressures characteristic of R744 systems, ensuring secure connections, accurate readings, and safe, stable operation.

As eco-friendly refrigerants gain wider adoption across the industry, R744 is drawing increasing attention for its natural origin and low global warming potential (GWP). Our R744 Gauge Set was developed specifically to meet this emerging demand, arriving fully equipped and ready to use out of the box. It is widely applied in the diagnosis and maintenance of CO₂-based refrigeration systems in commercial refrigeration and automotive A/C applications — a professional solution aligned with the industry's shift toward greener refrigerants.
