Plain & conductive PTFE convoluted tube is available from 1/4” to 6”NB in a range of standard wall thicknesses. A grade of modified PTFE is used for all sizes of convoluted tubing which gives the advantage of excellent flex-life when compared to all other fluoropolymers; reduced permeation characteristics & much improved stress crack resistance. Polyflon can supply convoluted tube in coils with plain cut ends or cut-to-length pieces with custom thermoformed ends to suit any connection type.
