## Summary description

Heat shrink tube HellermannTyton 323-20190 is a black insulating sleeve supplied as 40 pieces, each 1 m long. Designed for cable and wire insulation, it covers diameters from 6 mm down to 1.9 mm after shrinking. Suitable for protecting connections, providing strain relief and environmental sealing in electrical, automotive and industrial wiring applications.

## Long description

Heat shrink tube HellermannTyton 323-20190 is a black polyolefin sleeve supplied as a set of 40 pieces, each 1 m long. It is designed to insulate and protect electrical joints, provide mechanical strain relief and environmental sealing for wires and cables. The tube shrinks from an initial diameter suitable for 6 mm down to a recovered diameter of about 1.9 mm, creating a close-fitting protective layer over terminations, splices and connector bodies in electrical, automotive and industrial wiring applications.
Advantages
This heat shrink tube offers reliable insulation and abrasion resistance while maintaining flexibility after installation. The wide shrink range allows one size to accommodate several conductor and connector diameters, reducing part variety. The black color provides UV resistance and a discreet appearance for visible harnesses. Supplied in 1 m lengths, the product is convenient for cutting to required sizes and applying over a range of cable assemblies.
Suitable for
Insulating and protecting wire splices and solder joints
Providing strain relief on cable terminations and connectors
Environmental sealing against dust and light moisture
Repairing or bundling cable harnesses in vehicles and machinery
Key specifications
Material: cross-linked polyolefin (typical heat-shrink material for electrical insulation)
Color: black
Length per piece: 1 m
Pack quantity: 40 pieces
Shrink ratio/range: from nominal fit for 6 mm down to recovered diameter approximately 1.9 mm
Typical properties: electrical insulation, abrasion resistance and flexibility after shrinking
How to use
Measure and cut the required length of heat shrink tube, slide it over the cable or joint before making the connection if possible, then position it centrally over the splice or connector. Apply heat evenly using a heat gun, hot air tool or controlled flame until the tube has fully recovered and conforms tightly to the underlying component. Allow the tube to cool so it sets in its recovered shape and inspect the fit to ensure complete coverage and no gaps at the ends.
Usage recommendations
For consistent results, use a regulated heat gun at a moderate distance and move the nozzle steadily to avoid localized overheating. For applications requiring additional environmental protection, consider using adhesive-lined heat shrink variants or sealing the tube ends with appropriate adhesive or silicone where moisture ingress is a concern. Select the shrink tube size so the unshrunk diameter easily slides over the largest assembly and fully recovers down to the smallest diameter listed.
