Heat Sources & Gun Operation

How to operate a heat shrink tubing gun

Carefully follow all the manufacturer’s instructions for proper use of heat shrink tools.

Since heat gun temperatures vary widely, first test your heat gun by shrinking a small piece of shrinkable tubing over a sample product.

  1. Hold the heat gun about 4 inches (102mm) away from the tubing.
  2. Using a continuous circular motion, begin by aiming the heat at the center of the object. Direct the heat from the center outwards, towards the ends.*
  3. Apply heat to all sides of the object for uniform conformity.
  4. Trim excess tubing, if necessary.

*This will eliminate the possibility of trapping air and developing surface bulges.
