Comparison Thermoplastic tubes table

Thermoplastic tubes – a lightweight alternative to rubber

Thermoplastic tubes offer several advantages compared to rubber tubes, in particular:

  • Reduced weight: up to 75% lighter compared to rubber hoses. ​
  • Compact design: up to 25% smaller outside diameter compared to a rubber hose.​
  • Quick assembly: based on standard firtree Quick Connectors. No clamps needed.
  • Cost efficient: tailor made solution for battery thermal management systems. 

Laser welding – a space-saving assembly method

Compared to traditional assembly technologies, laser welding brings several benefits for your entire thermal management systems, including:

  • More design options for your engineers, as less space is needed for attaching tubes to interfaces
  • Extremely strong and reliable joints
  • Very clean assembly method
