Raychem QSZH-125 Heat Shrink Tubing – Halogen-Free Protection for Automotive Connections
The Raychem QSZH-125 heat shrink tubing from TE Connectivity is specifically designed for environmental sealing, mechanical protection, and electrical insulation of in-line splices in the automotive industry. This halogen-free, dual-wall heat shrink tubing offers reliable protection against harsh conditions typical of vehicle wiring, such as wear and damage.
Reliable Protection for Automotive Connections
The QSZH-125 heat shrink tubing is placed over the splice, and when heated, the adhesive melts, forming a tight seal around the wires. This ensures an excellent seal and protection for the connection, reducing the risk of short circuits or failures. The heat shrink tubing also provides mechanical protection against bending, wear, and abrasion, as well as electrical insulation for safe performance under various conditions.
Five sizes of the QSZH-125 heat shrink tubing are available, suitable for a wide range of automotive splice configurations, with the ability to cover up to seven wires on each side. The sizes are marked as 1, 2, 3, 3A, and 4, making it easy to select the right size based on the specific application.
