Techyours® offers FEP 1.3:1 shrink ratio tubing and FEP roll covers. FEP in these sizes is among the most popular heat shrink tubing product used for snug, protective jacketing for metal or other parts that are exposed to adverse, aggressive environments such as corrosion, chemicals, moisture and impact. The wide use of FEP heat shrink tubing over PTFE or PFA is due to its lower shrink temperature than either of those materials, as well as for its ease of installation.


The appropriate size of heat shrink tubing is selected based on the closest size that's smaller than the largest dimension of the product to be covered. The expanded ID for the selected tubing size is large enough so that the largest dimension of the product can fit inside the tubing. There may be an occasional overlap of sizes, where 2 consecutive sizes may work. Application of heat for a short time (using a heat gun, hair dryer) over the length from one end to the other is an adequate way to uniformly shrink the tubing quickly without wrinkles.
