Heat Shrink Teflon Tubing

Shrinking PTFE, FEP & PFA Tubing can be very time consuming and often lead to long down times. Tef Cap can help reduce down time on equipment and eliminate employee error by performing this process in house.

Most Fluoropolymers will begin shrinking around 230° F and see full recovery around 300° F, however temperature is not the only factor when shrinking Fluoropolymer Tubing. Time also plays and important role in the shrinking of FEP and PFA Tubing. A long heat soak is also important in making sure that you get full recovery from your tubing.

For applications that are using PTFE Tubing higher temperatures of 620°F are required in order for the material to begin its shrinking process. Even though PTFE Tubing can see higher temperatures than PFA and FEP during the shrinking process too much heat will cause PTFE to split longitudinally and have to be replaced.
