Convoluted PTFE Tubing

  • Translucent PTFE tubing offers excellent chemical and electrical properties
  • Wire coil provides increased pressure capability and aids in electrical grounding
  • Easily flexed – spiral construction allows far greater flexibility than straight wall tubing
  • Spiral construction also allows for easier cleaning
  • Made from FDA compliant materials
  • Available to Military Specification MIL-T-81914/1^ (without wire only)
