1. Product Features

Color distinction: ML-1234 quick connectors are distinguished by red and blue colors. The red connector represents the high-pressure part and the blue connector represents the low-pressure part, which is convenient for users to quickly identify and connect correctly.
Label indication: Each connector is equipped with "OPEN" and "CLOSED" labels to clearly indicate the opening and closing status of the connector, ensuring that users can accurately judge the status of the connector during operation and avoid misoperation.
High-pressure and low-pressure marking: The red connector is marked with a white "HI" mark above, indicating the high-pressure part; the blue connector is marked with a "LOW" mark above, indicating the low-pressure part, which further enhances the product's recognition and ease of use.
Threaded connection port: ML-1234 quick connector is equipped with a threaded connection port for easy connection to the refrigerant pipeline. This connection method is not only firm and reliable, but also ensures the sealing and stability of the refrigerant during transmission.
Pure white background design: The background of the product adopts pure white design, which is simple and generous, and it is easy to observe the status of the connector.

2. Application scenarios

ML-1234 quick connectors are widely used in various air-conditioning systems, such as household air-conditioning, commercial air-conditioning, and car air-conditioning. When repairing, maintaining, or replacing refrigerants in air-conditioning systems, this product can provide a fast and convenient connection solution to improve work efficiency.

3. Usage

Before use, make sure that the "CLOSED" label of the connector is closed to avoid refrigerant leakage.
Connect the threaded connection port of the connector to the refrigerant pipeline and ensure that the connection is firm.
Rotate the cap on the connector to open or close the connector as needed. When opening the connector, pay attention to the "OPEN" label; when closing the connector, pay attention to the "CLOSED" label.
After the connection is completed, please perform a leak test to ensure the sealing of the connector.

4. Precautions

Do not transfer refrigerant when the connector is not completely closed to avoid refrigerant leakage and environmental pollution.
During use, please pay attention to the status of the connector. If there is any abnormality, please replace or repair it in time.
Do not expose the connector to high temperatures or corrosive environments to avoid affecting its service life and performance.
