Suitable for sealing, mechanical protection and electrical insulation of cable joins and harnesses in industrial and installation applications.

## Long description

HellermannTyton 323-20750 is a black heat shrink tube designed for cable insulation and protection. The product is supplied as a pack of five 1-metre tubes and is intended to provide mechanical protection, sealing and electrical insulation for cable joins and harnesses in industrial and installation environments. The tube is made to be applied with heat to shrink around cables and connectors, creating a close-fitting layer that helps protect against abrasion and environmental exposure.
Advantages
The heat shrink tube offers a consistent black finish and a long 1 m length per piece, enabling coverage of multiple splice points or longer sections of harness. Supplied in a set of five, the tubes provide repeatable, uniform shrink performance for standard cable protection tasks. The material conforms to irregular shapes when heated, improving strain relief and reducing the risk of exposure at joins.
Suitable for
Insulating and protecting electrical cable joints and splices
Providing mechanical abrasion protection on wiring looms and harnesses
Sealing and environmental protection for outdoor or industrial cable runs
Marking or bundling cables where a black finish is acceptable
Key specifications
Color: black
Length per tube: 1 m
Pack quantity: 5 pieces
Nominal shrink application range: designed to shrink from larger to smaller diameters to form a tight fit over joins (product data indicates usable diameter range of 2.2–7.5 cm prior to shrinking)
Application method: heat shrink
How to use
Select a tube length that covers the splice or area to be protected with sufficient overlap on either side. Slide the tube over the cable or position it across the completed joint, then apply uniform heat with an appropriate heat gun or controlled flame source while rotating the assembly to ensure even shrinking. Continue heating until the tube has contracted snugly around the cable, eliminated air gaps and achieved the desired sealing and strain-relief effect. Allow the tube to cool before handling.
Usage recommendations
For consistent results, use a temperature-controlled heat gun and maintain a safe distance to avoid overheating. Ensure surfaces are clean and free of sharp edges or debris before application. Verify the tube size covers the unshrunk diameter range required for your cables; if tighter clearances or enhanced environmental sealing is needed, consider adhesive-lined or specially specified heat shrink variants.
