How To Use Guide-FEP Tex-Shrinkable Tubing   

Shrink Temperature: 410°F / 210°C  *  Over 1" dia. 430°F / 221°C

FEP heat shrink will grow in length during the shrink process.  On long objects, excess growth may cause wrinkles unless the FEP heat shrink is allowed to slide forward over the object. 

Installation

1. Read all instructions first. 
2. Large objects or solid rods must be pre-heated to get a uniform shrink on  the length of the large object being overheated.
3. If you have a long cable of tube to shrink over, start at one end and rotate while applying heat.  This will give a uniform shrink with no air bubbles between the shrink tubing and the rod or cable.
4. Heat uniformly around the shrink tubing until the tubing begins to shrink.  Avoid overheating the FEP shrink tubing or it will become brittle and have a cloudy look.  Before this happens, it will become crystal clear and melt and never recover fully. 
5. Remove the heat source.   Allow the shrink tubing to cool slowly.  Rapid quenching in water may freeze the material and prevent complete recovery.

CAUTION:  If the tubing cracks, you have probably over heated the material.
