Heat-Shrink Tubing Kit (127 pcs) GEKO G02924 — assorted sizes, adhesive-free

GEKO G02924 Heat-Shrink Tubing Kit (127 pcs) provides a selection of adhesive-free shrink tubes in assorted diameters and lengths for electrical insulation, wire protection and repair. The kit is intended for use with wiring harnesses, electronics projects and automotive repairs where flexible, silicone/PVC-compatible tubing that shrinks under heat is required to restore insulation, add strain relief or bundle conductors. Tubing in this kit is adhesive-free and designed to form a tight, insulating sleeve when exposed to heat, offering a simple mechanical solution for finishing and protecting splices and exposed conductors.

Advantages

The assortment of 127 pieces covers multiple sizes so you can select tubing that matches conductor diameters and splice points without needing separate purchases. Adhesive-free composition makes the tubes compatible with components and materials that may be sensitive to melting adhesives, while still providing reliable shrink performance for insulation and mechanical protection. Flexible material allows installation on bent or routed wiring runs and provides strain relief at solder joints, terminals and connectors.

Suitable for

• Repairing and insulating cut or damaged wires in household and automotive wiring
• Bundling and protecting cable assemblies in electronics projects
• Providing strain relief and insulation at solder joints and connector interfaces
• Temporary or permanent protection of splices during maintenance and prototyping

Key specifications

• Contents: 127 heat-shrink tubes in assorted sizes
• Type: adhesive-free (non-adhesive) heat-shrink tubing
• Material compatibility: silicone/PVC-compatible flexible tubing
• Function: electrical insulation, wire protection, strain relief
• Activation: heat-shrinkable when exposed to appropriate heat source

How to use

Select a tube with an initial diameter slightly larger than the conductor or splice, slide the tubing over the joint or cable, then apply controlled heat until the tubing uniformly contracts and conforms to the underlying shape. Heat sources can include a heat gun, hot-air station or other suitable controlled heating device; avoid open flames and excessive localized heat to prevent damage to adjacent components. After cooling, verify the tubing has fully closed around the conductor and provides adequate insulation and mechanical support.

Usage recommendations

For best results, pre-measure conductor diameters and choose tubing that achieves snug coverage after shrinking. Use a regulated heat gun and move evenly along the tube to ensure uniform shrinkage; allow tubes to cool before flexing. Store the kit in a dry, cool place away from direct sunlight to preserve material flexibility and shrink performance.
