R410 R22 Freon Charging Gas Ac Car Air Conditioner Manifold Pressure Gauge for Refrigerant

  A multi-functional detection tool specifically designed for automotive air conditioning systems, used for refrigerant charging, pressure monitoring, and fault diagnosis. It is compatible with mainstream Freon refrigerants such as R410A and R22, and is suitable for maintenance technicians and DIY users.

Key features

1.Dual - gauge Pressure Monitoring: Equipped with a high - pressure gauge (red) and a low - pressure gauge (blue), which can respectively display the pressure values of the high - pressure side and the low - pressure side of the air - conditioning system in real - time, assisting in judging the operating status of the system.
 

2.Refrigerant Charging and Recovery: Integrated with a three - way valve group, it supports forward charging, recovery/evacuation.
 

3.Vacuum Extraction and Leak Detection: The middle interface can be connected to a vacuum pump to evacuate the system, ensuring that the system is dry and clean before charging; and to detect the tightness of the pipeline.
 

4.Temperature Comparison and Fault Analysis: Some model dials are marked with a pressure - temperature correspondence table, which can quickly locate faults.

Advantages
1.Strong Compatibility: Compatible with R410A, R22 and other CFC/HCFC refrigerants, covering mainstream automotive air - conditioning systems.
 

2.Durability Design: The gauge body is made of shock - proof metal shell, which is drop - resistant and wear - resistant; the internal Bourdon tube is made of corrosion - resistant material, suitable for long - term contact with refrigerants.
 

3.Convenient Operation: The color markings are clear, and the supporting quick - connectors can be used to connect to the high - and low - pressure maintenance ports (Schrader valves) of automotive air - conditioners with one - click, reducing the risk of misoperation.

Applications
1.Daily maintenance: Detect the refrigerant pressure when the cooling effect of the air conditioner decreases, and determine whether it is necessary to refill or replace the refrigerant.
 

2.Debugging after major repairs: After replacing components of the system (such as the compressor, evaporator), evacuate the system and accurately charge the specified amount of refrigerant.
 

3.Fault diagnosis: Judge problems such as insufficient compressor efficiency, condenser blockage, and expansion valve failure through abnormal high and low pressure gauge values (such as too high high pressure and too low low pressure).
