Heat-shrink tubing CellPack 143563, single piece, polybag packaging

CellPack 143563 is a single-piece heat-shrink tubing supplied in polybag packaging, intended for electrical insulation, protection and strain relief of cables, joints and components. The tube is halogen-free and stabilized against UV rays, offering waterproof and pressure-tight performance as part of repair, cable management and component-protection tasks in electronic and electrical installations. The package contains one unit; specific pre- and post-shrink dimensions are not provided by the manufacturer.

Advantages

The tubing provides superior electrical and mechanical properties suitable for maintaining insulation integrity and mechanical reinforcement around connectors and splices. Its halogen-free composition reduces toxic emissions in the event of fire, while UV stabilization increases outdoor durability. Being 100% waterproof and pressure-tight, the product supports reliable sealing of joints and protection against moisture ingress in demanding environments.

Suitable for

• Repairing damaged cable insulation and restoring dielectric separation
• Sealing and protecting splices and connector joints in electrical installations
• Strain relief and reinforcement of cable entries into housings and components
• General cable management and insulation in electronics and automotive applications

Key specifications

• Material: heat-shrinkable polymer (single-piece construction)
• Packaging: single unit in polybag
• Chemical properties: halogen-free formulation
• Environmental resistance: stabilized against ultraviolet (UV) radiation
• Ingress protection: 100% waterproof and pressure-tight when properly shrunk
• Electrical properties: designed for superior electrical insulation performance
• Mechanical properties: enhanced mechanical strength for strain relief and abrasion resistance

How to use

Position the CellPack 143563 heat-shrink tubing over the area to be insulated or reinforced, ensuring adequate coverage of the joint, splice or cable section. Apply uniform heat using a heat gun or other suitable heat source to the tubing until it contracts evenly and forms a tight seal around the substrate. Allow the assembly to cool so the tubing fully conforms to the underlying shape. Follow standard safety practices when using open heat sources and ensure compatibility with surrounding materials before application.

Usage recommendations

For reliable results, select a heat source that provides controlled and even heating to avoid overheating nearby components. Verify that the tubing diameter before shrinking is appropriate for the cable or joint and allow adequate overlap beyond the splice. For outdoor applications, ensure the tubing is fully shrunk and sealed to maintain waterproofing; for critical electrical installations, inspect the finished assembly to confirm mechanical and electrical integrity.
