## Long description

Heat shrink tube ORNO 4 mm, 1 m, black is a single-wall heat-shrink sleeve intended for insulating and protecting electrical connections, cable joints and terminations. Supplied in a blister pack, this 1 m length of 4 mm diameter tubing provides mechanical protection, moisture resistance and strain relief for wiring in household, automotive and electronics repair tasks. The black colour offers a neutral, low-visibility finish suitable for most wiring applications.
Advantages
The heat shrink tube offers consistent shrink ratio and tight, conforming coverage of connectors and splices when heated. Its material provides electrical insulation and basic moisture protection while reducing mechanical stress at cable transitions. The product is easy to cut to length, lightweight to store and simple to use with standard heat sources such as a heat gun or lighter when applied with care.
Suitable for
Insulating soldered joints and crimped terminals
Protecting wire splices in household wiring and small appliances
Securing and finishing cables in automotive and motorcycle wiring repairs
Organizing and marking wiring in electronics prototyping and repairs
Key specifications
Nominal expanded diameter: 4 mm
Length: 1 m
Colour: black
Single-wall construction for general-purpose insulation
Suitable shrink method: application of controlled heat (heat gun, hot air or similar)
How to use
Select a section of tubing slightly longer than the connection or splice to be insulated. Cut the tube cleanly with scissors or a sharp blade, slip it over the joint, then apply even heat until the tubing contracts and conforms tightly to the underlying components. Allow the tubing to cool before handling to ensure a secure fit. When using an open flame, keep a safe distance and move the heat source continuously to avoid burning the material or the insulated conductors.
Usage recommendations
For reliable results, choose tubing with an appropriate expanded diameter so it fully covers the connection before shrinking. Use a regulated heat gun or hot-air tool for even heating; avoid prolonged exposure to open flame. For applications exposed to water or oil, consider selecting heat shrink with adhesive lining or a specialised jacketed sleeve designed for enhanced environmental sealing.
