Shrink Tubing

Shrink Tubing
Shrink tubing is a versatile tool for insulating or marking cables, commonly used in both home settings by DIY electricians and in industrial cable harness production. These special plastic tubes, known as heat shrink tubes, contract significantly when exposed to heat, providing protection against mechanical damage and offering electrical insulation. The most widely used method for this application involves hot air, and Leister stands out as a market leader with extensive experience in this area.

Electrical applications

Whether you’re an electrician, a car mechanic, or a DIY enthusiast, heat shrink tubes are invaluable for marking, repairing, and insulating electrical lines.
A heat gun is used to shrink the tube around the cable, ensuring a secure and protective fit. In electrical engineering, these tubes are often used to connect two cables permanently, utilizing a prefabricated crimp connection shielded by a heat shrink hose to maintain electrical conductivity. In the automotive industry, these tubes are essential for replacing or repairing cables during vehicle restoration, maintenance, or repairs. Leister and Weldy offer a wide range of heat guns and specialized nozzles, making it easy to achieve perfect results when shrinking sleeves and heat shrink tubes, whether for DIY projects or professional use.

Industrial cable harness production

In industrial settings, cable harnesses are often assembled by hand, with Leister and Weldy heat guns being the tools of choice for continuous, reliable performance.
The process of shrinking tubing in industrial production mirrors that of home use but on a larger scale. Cable harnesses are typically prefabricated in large quantities, with multiple connections marked and insulated using heat shrink tubes. Crimping is also a standard practice, ensuring secure and conductive connections. During final assembly, especially in the automotive industry, cable harnesses are manufactured in various sizes to meet specific customer requirements.

Leister not only provides the necessary hot air tools but also offers special nozzles and accessories to ensure precise and efficient shrink tubing in any application. Whether you’re working on a small DIY project or managing large-scale industrial production, Leister has the right solution for all your shrink tubing needs.
