Heavy duty heat shrink tubing is more than meets the eye. It is extremely versatile but when low quality materials are used incorrectly, it can result in costly damages. The tubing protects from moisture, chemicals, and abrasions guaranteeing the reliability, longevity, and safety of aircrafts and automobiles. It’s also used to insulate cables, wires, and pipes. Protecting them from moisture, chemicals, mechanical stressors, and environmental factors such as UV Radiation, lengthens the life and reliability of the electrical connections and pipes.
