When the motor, electronic control and battery pack are tested for air tightness, the interfaces on the sealing shell shall be blocked, such as explosion-proof valve interface, coolant interface and various electrical connector interfaces. The sealing of these interfaces during the test is very important. The GripSeal quick seal connector passes strict air tightness test before delivery, which can effectively detect the sealing performance of the motor, electronic control and battery pack, providing strong guarantee for the safe operation of new energy vehicles.

Air tightness testing of the "three electric" housing of new energy vehicles：

1. The special plug for G20F explosion-proof valve can closely fit the explosion-proof valve interface to ensure that there is no gas leakage during the test.

2. G25F electric connector port sealing special quick connector, with exquisite design, can be perfectly connected with connector interface, and also achieve good sealing effect.

3. G70 series fast connector is designed for fast sealing of flange nozzle and J2022 nozzle, end face sealing and sliding sleeve operation to reduce operation strength and improve efficiency.

4. G90 series fast sealing connector is specially designed for fast sealing of VDA male pipe orifice, with handle operation, high sealing level and 360 ° rotation of air inlet port, eliminating the trouble of air pipe winding.
