How Do I Shrink a Raychem (Tyco Electronics) Heat Shrink Sleeve?

Question:  How do I shrink a Raychem heat shrink sleeve?

Answer:  You've got a couple of options.  First and foremost it is important to know that the backing of the sleeve will begin to shrink once it reaches a temperature in the vicinity of 267F (there is a generalization as some Raychem sleeve backings do shrink at higher or lower temperatures than this).

In any case; the question now becomes; how do I get the backing to reach that 267F temperature?  This can be done easily with a small propane (or other) torch.  You want to make sure that you have a torch that puts out a 'bushy', broad flame.  Acetylene or welding torches will not work well in this role.

Bernzomatic torches do an excellent job of shrinking our Raychem heat shrink sleeves.

An industrial hot air gun can also be used to excellent results.
 Otherwise, you also have the option of using a hot air gun of some kind to do the job.  It could possibly take a bit longer (depending on the air gun) but ultimately you will achieve the same exact result.
