Brass manifold gauge set
The CT-356 brass manifold gauge set is a diagnostic and service tool. Used by HVACR (Heating, Ventilation, Air Conditioning, and Refrigeration) technicians to work on air conditioning and refrigeration systems.
Its primary uses include:
- Checking System Pressures. It measures the high-side (discharge) and low-side (suction) pressures. Of the refrigerant within an AC or refrigeration system to help diagnose whether it’s operating correctly.
- Leak Detection: By analyzing pressure changes over time, technicians can identify potential refrigerant leaks in the system.
- System Evacuation/Vacuum. It is used in conjunction with a vacuum pump. To remove air and moisture from the system before charging with new refrigerant.
- Refrigerant Charging. The set allows for the safe and precise addition of the correct amount of refrigerant to a system to ensure optimal performance and efficiency.
- System Recovery: It can be used as part of the process to recover contaminated or excess refrigerant from a unit into a recovery cylinder.
Compatible with common refrigerants like R134a, R22, R410A, and R404A.
