Specifications: Material: aluminium Color: blue Size: length: 15.75 inch Weight: 272g/9.6oz Quantity: 1 Features: -1.The pressure gauge installed on the product dynamically reflects changes in the air conditioning system's pressure, providing a clear numerical display that serves as an intuitive reference for troubleshooting air conditioning malfunctions. -2.The interface threads of this product have undergone precision machining, ensuring a high fit with the R134a valve, effectively preventing refrigerant leakage during the charging process.

• High Quality Material: This product is crafted from high-quality aluminium. Aluminium exhibits excellent thermal conductivity, enabling rapid adaptation to temperature fluctuations during refrigerant charging while maintaining stable pipe conditions. Its robust construction withstands charging pressures without deformation. These physical properties ensure reliable performance, meeting core automotive air conditioning maintenance requirements.
• Versatile Application: With a total length of 15.75 inch, this product is compatible with automotive air conditioning systems featuring standard R134a, R12, or R22 connectors, offering comprehensive adaptability. It meets the requirements of most vehicles, including saloon cars, SUVs, lorries, and vans, provided their air conditioning systems incorporate the aforementioned standard connectors.
• Easy Installation: First, securely connect the self-sealing dispensing valve to the refrigerant cylinder, rotating it firmly to ensure a leak-free seal. Next, locate the corresponding port on the vehicle's air conditioning system. Align the low-pressure quick-connect fitting precisely and connect it, ensuring a tight seal. Finally, slowly open the low-pressure valve to allow the refrigerant to flow in at a steady rate, monitoring the pressure gauge readings throughout the charging process.
• Real Time Pressure Monitoring: The integrated pressure gauge provides instantaneous readings of the vehicle's air conditioning system pressure, offering clear feedback on pressure fluctuations. This facilitates rapid identification of abnormal pressure conditions, providing a precise reference for troubleshooting system issues. Coupled with a precision control valve, it enables metered refrigerant charging, ensuring accurate control of the charge quantity.
• Secure Sealing: The product's threaded interface achieves a tight fit when connected to R134a valves, delivering robust sealing performance. This high-precision design effectively prevents refrigerant leakage during charging. This ensures peace of mind during air conditioning refrigerant replenishment, guaranteeing safety and reliability throughout the process.
