Flexible, chemically inert, and resistant to melt-off by soldering irons, this tubing is ideal for electrical insulation. The convoluted tubing is perfect for interconnect recipes which have the conductors spiralled around the outside of the tube or recipes that use foil conductors. Unlike regular thin wall PTFE tube the convoluted tubing will bend to a .313" radius without kinking! Meets Mil Spec. MIL-T-81914. Temperature range is -400° to +500° F. Color is natural.
