How to install 3M Heat Shrink Tubing?

To install 3M Heat Shrink Tubing, slide the tubing over the wire or connection before shrinking. Apply heat evenly using a heat gun or torch until the tubing tightly conforms to the substrate. Allow it to cool completely. Ensure the inner diameter before shrinking (0.38 in) fits over the component, and the after-shrink diameter (3 in) provides a snug seal.
