Standard Flex Convoluted ETFE Tubing • 81914/6

Convoluted ETFE Tubing Standard Flex is engineered to meet Mil Spec 81914/6 and is perfect as a secondary containment tube or complete conduit system for wires and harnesses. Designed from a rigid Fluoropolymer tube, convoluted ETFE is chemically inert and highly impact resistance yet is extremely light weight which makes it an ideal tube for Aerospace applications.

Convoluted ETFE Tubing will operate in applications where high temperatures are required and other materials are not suitable. Even at extreme temperatures ETFE tubing will keep and maintain it mechanical properties. Mil-Spec Convoluted ETFE (AMS-T-81914/6 or M81914/6) is an excellent electrical insulator and resists almost all corrosive liquids and solvents including acids.


  • Convoluted ETFE Tubing is ideal for applications that require high pressure ratings.
  • ETFE Convo has a greater crush resistance than PTFE & FEP.
  • Convoluted ETFE Tubing is self draining and ultra light weight.
  • Max working temperature : 302°F
