Heat Shrinkable Tube – Φ3 mm Brown, 200 m Roll

Detailed Description:
This high-quality heat shrinkable tube features a nominal un-shrunk internal diameter of 3 mm (Φ3 mm) and is supplied in a 200-metre roll, making it ideal for bulk installations or large-scale wiring harness production. The tube is made from cross-linked polyolefin (or equivalent heat-shrink material) that provides excellent insulation, abrasion resistance and environmental protection when fitted and shrunk over wire, cable joints, splices and connectors. Key features include:

• Nominal diameter: Φ3 mm before shrink, fits over wires/cables of approximately 3 mm outer diameter (verify fit).

• Colour: Brown – useful for colour-coding, visual identification or matching enclosure aesthetics.

• Roll length: 200 metres – economical for large runs, wiring harness factories or service stock.

• Material: Polyolefin (typical) heat-shrink tubing that shrinks radially when heated, to provide a snug, conformal cover over wires and joints.  

• Typical shrink ratio: 2:1 or 3:1 depending on variant – meaning it shrinks to half or one-third of original diameter. For example, many brown tubing products specify 2:1 shrink ratio. 

• Operating environment: Suitable for insulating and protecting cables in wiring looms, control panels, automotive assemblies, industrial harnesses and general-purpose electrical installations.

• Benefits: Provides reliable insulation, strain relief, colour coding and protection from dust/dirt; helps achieve neat and professional cable terminations and repairs.

• Installation tips: Slide the un-shrunk tubing over the wire or splice, apply uniform heat (e.g., hot-air gun) until the tubing fully contracts and conforms around the substrate. Avoid direct flame contact to prevent damage.
