Heat shrink tubing CellPack 144400, length 100 cm, single-piece pack

CellPack 144400 heat shrink tubing is a single-piece, 100 cm length tube designed for electrical insulation and mechanical protection of wiring, cable joints and terminals. The thin-wall construction provides a close fit after shrinking, improving moisture resistance and offering reliable dielectric properties for repair, sealing and insulating tasks in domestic and light industrial electrical and electronic applications.

Advantages

The tubing is non-adhesive and inscribable, enabling marking with pens or labels before installation. It is resistant to many chemical agents, stabilized against UV radiation and free from paint-wetting inhibiting substances, which helps maintain performance in exposed or treated environments. High flexibility, elevated tensile strength and thermal stability reduce the risk of cracking or cold flow over time, while self-extinguishing properties (except for transparent variants) increase safety in case of overheating.

Suitable for

• Insulating and protecting splices and cable joints
• Repairing damaged cable insulation
• Covering and identifying terminals and connectors
• Sealing against moisture in wiring harnesses and small assemblies

Key specifications

• Material: thin-wall heat-shrink polyolefin (non-adhesive)
• Length: 100 cm (single piece)
• Mechanical: high tensile strength and high flexibility
• Electrical: superior dielectric properties suitable for insulating connections
• Chemical and environmental resistance: resistant to chemical agents, UV-stabilized, non-corrosive
• Thermal behavior: thermally stable with resistance to cold flow; self-extinguishing (except transparent)
• Surface: inscribable for labeling and identification

How to use

Slide the heat shrink tubing over the cable, splice or terminal before making the electrical connection where applicable. After positioning, apply uniform heat using a heat gun, hot air tool or controlled heat source until the tubing contracts evenly and forms a snug, continuous seal around the component. Allow the tubing to cool to ensure a stable mechanical and electrical fit. For precise shrinking, maintain a safe distance and move the heat source steadily to avoid local overheating.

Usage recommendations

Use appropriate personal protective equipment and a regulated heat gun to avoid damage from excessive heat. Choose the correct tubing diameter relative to the component before shrinking to ensure a secure fit. If environmental sealing is required, verify suitability for the specific chemicals or fluids present and consider adhesive-lined heat shrink where an adhesive bond is needed (this product is non-adhesive).
