Heat Shrinkable Tube – Φ16 mm Blue, 100 m Roll

Detailed Description:
This premium heat-shrinkable tubing is supplied in a continuous 100-metre roll and features a nominal undeployed internal diameter of approximately 16 mm (Φ16 mm) before shrinking. The blue colour makes it ideal for colour-coding wiring bundles, marking circuits or matching installation aesthetics. Manufactured from high-quality cross-linked polyolefin (or equivalent), this tubing offers excellent electrical insulation, mechanical protection and environmental sealing when applied over cables, splices, connectors or wire harnesses.

Key Features:

• Nominal inner diameter: ~16 mm (before shrink) — suitable for sliding over larger cables or bundles and then shrinking to form a snug, protective cover.

• Colour: Blue — useful for visual identification, wiring harness colour-coding, or integrating with system colour schemes.

• Roll length: 100 metres — cost-effective for moderate to large installations, service stock or wiring-harness production.

• Material & performance: Polyolefin heat-shrink tubing offers superior insulation, good abrasion and chemical resistance, flame retardancy and a wide operating temperature range. 

• Shrink behaviour: On heating, the tubing contracts radially (and slightly longitudinally) to conform tightly to the substrate—common shrink ratios in polyolefin tubing include 2:1, 3:1 or 4:1. 

• Applications: Ideal for insulating and protecting cable bundles, splices, terminations in industrial installations, control panels, automotive wiring, telecom/IT installations where a ~16 mm cover is needed and blue colour is preferred.

• Installation Guidance: Slide the un-shrunk tubing over the cable or bundle before making the connection. After the joint or bundle is assembled, position the tubing over it and apply uniform heat (e.g., a hot-air gun) until the tubing fully recovers and conforms. Avoid direct flame contact, ensure even heat application. 

• Benefits:

  • Provides a professional-looking finish and cable bundling neatness.

  • Enables colour coding of circuits and improved wiring organisation.

  • Offers reliable insulation and mechanical/abrasion protection.

  • Bulk roll format (100 m) supports efficient installation with fewer roll changes.
