This charging valve set is a specialized tool for automotive air conditioning systems, featuring two connectors—red (high-pressure side) and blue (low-pressure side). Made from brass material, it is corrosion-resistant and highly sealed, compatible with refrigerant charging ports on most vehicle models.
Its knob-style design ensures easy operation: simply align it with the air conditioning pipe interface, tighten, and then safely perform refrigerant charging and pressure testing. The red and blue color coding helps distinguish high and low-pressure ends, preventing incorrect connections. Suitable for automotive air conditioning maintenance, refrigerant replenishment, and other scenarios, it serves as a practical tool accessory for auto repair professionals or self-driving car owners.
Note: Follow the automotive air conditioning operation guidelines during use. It is recommended to operate by a professional or refer to the equipment manual
