EV Charging Gun Rubber Cover

The EV charging gun rubber cover is a core component that ensures the dustproof and waterproof protection of the car charging gun. During product design, our R&D team considered that the surface temperature of the charging gun can reach 60°-70°C in summer. Therefore, we use special flame-retardant rubber as the raw material, which effectively prevents softening and the release of toxic gases. Furthermore, through a 1000-hour outdoor exposure simulation test, the EV charging gun rubber cover showed no signs of powdering or cracking.
