## Summary description

Heat shrink tube HellermannTyton 323-20630 is a black cable insulation sleeve supplied as 6 pieces, each 1 m long. It shrinks from a minimum diameter of 6.3 mm to a maximum diameter of 19 mm, providing protective insulation and strain relief for wiring, connectors and splices. Suitable for electrical insulation, corrosion protection and mechanical protection in industrial and installation applications.

## Long description

Heat shrink tube HellermannTyton 323-20630 is a black, polyolefin-based insulation sleeve supplied as a pack of six 1 m lengths. Designed to provide protective insulation, strain relief and environmental sealing for wiring, connectors and splices, this shrink tube reduces its diameter from 19 mm to approximately 6.3 mm when heated, forming a tight, durable cover around cables and components used in industrial and installation environments.
Advantages
The tube offers reliable electrical insulation and mechanical protection for single cables and bundled conductors. Its heat-shrink behaviour creates a close-fitting layer that improves strain relief at connection points and helps prevent moisture and corrosion ingress. Supplied in multiple 1 m pieces, the pack format reduces waste and supports flexible planning of on-site repair or installation jobs. The black colour provides discrete visual integration into existing cable runs.
Suitable for
Insulating individual wires and multi-core cable joints
Protecting connectors, terminals and soldered splices
Providing strain relief at cable exit points
Environmental sealing against moisture and dust in installations
Bundling and repair of power and signal cables in industrial equipment
Key specifications
Material: cross-linked polyolefin (heat-shrinkable)
Colour: black
Pack quantity: 6 pieces
Length per piece: 1 m
Recovered inner diameter range: approximately 6.3 mm (minimum) to 19 mm (maximum before shrinkage)
Shrink ratio: designed to reduce from the larger supplied diameter to the smaller recovered diameter when heated
Typical uses: electrical insulation, mechanical protection, corrosion resistance
How to use
Cut a length of tube sufficient to cover the area to be protected with some overlap. Slide the tube over the cable, connector or splice, then apply even heat using a heat gun or controlled heat source until the tube uniformly conforms to the underlying surface and the diameter reduces to form a tight seal. Allow the tube to cool before handling. Follow standard safety practices when working with heated tools and live circuits: isolate power where possible and verify the compatibility of the shrink material with your application.
Usage recommendations
For best results, select a tube length that permits 5–10 mm overlap beyond the protected area. Use a regulated heat gun at appropriate temperature settings for polyolefin materials to avoid overheating. When insulating critical or high-voltage connections, ensure the recovered wall thickness and dielectric properties meet your application requirements and consult applicable standards or technical datasheets where necessary.
