In the engine compartment, extreme conditions are all too frequent: High temperatures, dirt, moisture and fuel vapors afflict power cables and weatherpacks. These connectors are best insulated with weatherpacks or single-wire seals of WACKER liquid silicone rubber. These silicone seals exude a microscopic film of water-repellent silicone fluid that additionally serves as lubricant during assembly. Whether operating under temperatures of 180 °C or early-morning frosts of -40 °C, the silicone gasket keeps working perfectly throughout the vehicle’s lifetime.
