Sealing Electrical Splices in Heavy Equipment

The sealing of electrical splices in heavy equipment has become an important element in increasing the life and reliability of both on and off-the-road vehicles. Adhesive lined heat shrink tubing is an effective protective and sealing method for these splices; it protects splices from the mechanical, electrical, chemical and temperature environments that exist in heavy equipment operation. In addition, the tubing meets the production requirements of reproducible installation at production rates and low installed cost.

This paper will focus on one heat shrink tubing system which was designed for the sealing of vehicular electrical splices. It will discuss the design requirements, manufacturing methods and installation techniques and mechanisms for this heat shrink tubing system.
