Polyolefin heat shrink tubing is a versatile solution used in military, commercial, and consumer applications. Designed for reliable insulation, protection, and strain relief, this tubing shrinks in both diameter and length when heated. With a 4:1 shrink ratio, it reduces to a quarter of its original diameter while experiencing minimal length shrinkage (typically less than 7%). It's important to note that heat shrink tubing is measured in its round form, not when flattened, so always choose a size slightly larger than the object you need to cover for a secure fit.
About this Item
RoHS Compliant
UL Listed
Halogen-Free
Up to 600V
Features
High temperature resistant.
High electrical insulation, sealing and corrosion resistance.
Used in wiring, automotive and many other electronic and electrical applications.
A 4:1 heat shrink tubing reduces its diameter to a quarter of its original size when heat is applied.
This means that if its original diameter was 1.2 inches, it will shrink down to 0.3 inches after heat is applied.
Instructions
Step 1: Measure & Cut
Measure and cut the necessary length of heat shrink tubing.
Step 2: Insert the Tubing
Slide the tubing over the wires before making the connection.
Step 3: Apply Heat
Apply heat using a heat gun or lighter to shrink the tubing securely around the connection.
Step 4: Sealed & Protected
Once cooled, the tube retains its new tight form, providing electrical insulation, mechanical protection, and moisture resistance.
Examples of different applications:
Heat shrink tubing is incredibly versatile and is used in many applications beyond electrical insulation.
