Heat shrink tube Brother HS2-631 yellow 11.7 mm × 1.5 m

Heat shrink tube Brother HS2-631 yellow 11.7 mm × 1.5 m is a flexible insulating sleeve in bright yellow with a nominal diameter of 11.7 mm and a total length of 1.5 m. The product is designed to shrink when exposed to heat, forming a tight, protective covering over wires, cable joints and connector ends. It is intended for electrical insulation, mechanical strain relief and visual cable identification in electronics, automotive and industrial wiring tasks.

Advantages

The yellow heat shrink tube provides consistent radial shrinkage to secure coverings around irregular shapes and joints without leaving adhesive residue. Its flexible polymer construction resists abrasion and provides basic protection against moisture and dust when properly applied. The visible yellow colour helps with fast identification and colour-coding of circuits and harnesses, and the 1.5 m length allows multiple cuts to size for different tasks.

Suitable for

• Electrical insulation of single conductors and splices
• Strain relief on connector joints and cable ends
• Colour-coding and visual identification of wiring
• Repairing damaged insulation on automotive wiring
• Small harnesses and DIY electronics projects

Key specifications

• Colour: yellow
• Nominal initial diameter: 11.7 mm
• Length: 1.5 m
• Material type: heat-shrinkable polymer (insulating sleeve)
• Shrink action: radial shrink when heated to recommended temperature
• Typical uses: insulation, strain relief, identification

How to use

Cut the required length of heat shrink tube and slide it over the wire or joint before making the electrical connection where applicable. Apply heat evenly using a heat gun, hot air tool or another controlled heat source until the tube shrinks uniformly and conforms to the underlying shape. Allow the sleeve to cool so it sets in place. Do not overheat; follow safe heating practices to avoid damage to surrounding components.

Usage recommendations

Use appropriate personal protective equipment and a regulated heat source. For higher moisture protection or harsh environments, consider selecting a tube with adhesive lining or a material specified for increased chemical and temperature resistance. Verify final fit and insulation before returning circuits to service.
