Example Installation Scenario
Consider an installer working on a marine electrical system that requires watertight seals for cables exposed to harsh marine environments. By using the Thermosleeve CBDWT3X3/8R4, the installer can cut the tubing to the required length, slide it over the cable connection, and apply heat with a heat gun. As the tubing shrinks, the adhesive lining melts and flows, creating a tight, watertight seal around the cable. This process ensures long-term protection against water ingress and corrosion, which is critical for marine applications.
