Battery Degassing Pipes Image Text

Battery gas vent lines

Gas vent lines are used when the batteries must be degassed within 5 seconds. In the process, temperatures of up to 700 °C occur.

  • suitable for 48-volt electrical power supply of vehicles and for high-voltage batteries of vehicles
  • technically gas-tight
