Heat Shrinkable Tubing 4:1 PTFE transparent in a length of 4.75/1.27
Art.-No. 339-00340 | TFE4-3/16-PTFE-CL

Copied
  • TFE heat shrink tubing is specified predominantly because of its very high temperature resistance.
  • It is an extra thin walled transparent tubing that has both high abrasion resistance and good resistance against aggressive chemicals.
  • TFE is available in either 2:1 (TFE2) or 4:1 (TFE4) shrink ratios.
Package size
Application TFE is ideal for high temperature applications, when resistance to aggressive fluids is required or a very thin walled tubing is needed, for example in pH-measuring instruments. TFE tubing is also used to reduce movement due to friction, covering cylinders for example.
