## Summary description

Radpol KTK 40/15 is a black heat-shrink end cap designed for insulating and protecting cable ends and connectors. Supplied in a pack of 100, these shrink caps provide mechanical protection and environmental sealing when heated to shrink around wires or terminals. Suitable for electrical and electronics installations where compact end insulation and strain relief are required.

## Long description

Radpol KTK 40/15 black heat-shrink end caps, supplied in a pack of 100, are designed to insulate and protect exposed cable ends, terminations and small connectors. Made from a heat-shrinkable polymer, each cap contracts when heated to form a tight sleeve that provides electrical insulation, mechanical protection and resistance to dust and moisture. The compact 40/15 size fits a range of cable diameters and is suitable for use in electrical, electronic and automotive assemblies where a neat, sealed finish is required.
Advantages
These heat-shrink end caps deliver consistent shrink performance and reliable sealing around wire ends and terminals. Their black finish offers visual uniformity and UV stability for indoor and limited outdoor use. Supplied in a pack of 100, the caps are convenient for bulk installations, service work and stockkeeping, reducing preparation time on site. The material provides both electrical insulation and mechanical strain relief to help prevent damage at connection points.
Suitable for
Insulating and sealing cut cable ends and stripped conductors
Protecting small connectors, terminals and splices
Automotive wiring repairs and harness protection
Electronics assemblies and appliance wiring
Key specifications
Color: black
Type: heat-shrink end cap (closed-end)
Nominal expanded/installed size: 40/15 (suitable for indicated cable diameter range)
Pack quantity: 100 pieces
Material: heat-shrinkable polymer providing electrical insulation and mechanical protection
How to use
Slide the end cap over the exposed cable end or terminal so that the closed end covers the conductor or connector. Apply heat evenly using a heat gun, hot air tool or suitable heat source, maintaining a safe distance and moving the heat source to avoid overheating. Heat until the cap has fully contracted and formed a snug, continuous sleeve around the cable; allow to cool before handling. Ensure the chosen cap size is compatible with the conductor diameter before shrinking.
Usage recommendations
For best results, use a regulated heat gun and apply heat uniformly to avoid local overheating. Inspect shrunk caps for complete adhesion and any signs of degradation. Store unopened packs in a cool, dry place away from direct sunlight. Select the correct size variant for the conductor to ensure an effective seal and strain relief.
