## Summary description

Radpol KTK WKKK18016000020C0 is a heat-shrink end cap (kapturek) for cable termination with nominal size 18/6. The thermally shrinkable sleeve provides mechanical protection and environmental sealing for cable ends and splices. Suitable for use in electrical installations to insulate and protect exposed conductors, joints and cable terminations.

## Long description

Radpol KTK WKKK18016000020C0 18/6 heat-shrink end cap is a thermally shrinkable cable end sleeve designed for insulating and protecting cable terminations and exposed conductor ends. The sleeve forms a tight, protective layer after heat application, providing mechanical protection and environmental sealing for cable ends and splices in electrical installations. Its nominal size 18/6 denotes the recommended cable diameter range and wall thickness after shrinkage.
Advantages
The thermally shrinkable material ensures a uniform, gap-free seal that resists moisture and dust ingress while providing strain relief at the termination point. The end cap maintains dielectric insulation and reduces the risk of short circuits by fully covering exposed conductors. The compact design and ease of installation reduce assembly time on the job site and enable reliable, long-lasting protection in both indoor and outdoor applications.
Suitable for
 Insulating and sealing cable ends in electrical installations
 Protecting splices and exposed conductors in control and power cables
 Providing mechanical protection and environmental sealing for terminations in junction boxes
 Field and factory cable termination work where a reliable shrinkable end cap is required
Key specifications
 Type: heat-shrink end cap (thermally shrinkable sleeve)
 Nominal size: 18/6 (sleeve inner diameter range and final wall thickness after shrinkage)
 Material: cross-linked polyolefin (heat-shrink polymer)
 Primary functions: electrical insulation, mechanical protection, environmental sealing
 Application temperature: requires controlled heating for proper shrinkage and sealing
 Suitable environments: indoor and outdoor use when properly installed
How to use
Slide the heat-shrink end cap over the cable end or splice so the sleeve fully covers exposed conductors. Apply heat evenly using an appropriate heat gun or controlled heat source, moving the heat source along the sleeve until the material contracts and forms a tight seal around the cable. Allow the sleeve to cool and verify that the shrinkage produced a gap-free, uniform coating. For multi-core or irregular terminations, ensure full coverage and avoid overheating adjacent components.
Usage recommendations
Use a regulated hot-air gun for even heating and avoid open flames or excessive localized heat that could damage the cable insulation. Confirm compatibility of the shrink material with the cable jacket and operating conditions. For outdoor or submerged applications, inspect the installed seal for continuity and consider additional sealing measures if required by the installation environment.
