Heat Shrinkable Tube – Φ20 mm Grey, 100 m Roll

Detailed Description:
This premium heat-shrinkable tubing is supplied in a continuous 100-metre roll, with a nominal undeployed inner diameter of approximately 20 mm (Φ20 mm) before shrink. The tube is coloured grey, which is ideal for neutral wiring bundles, industrial/civil installations, or where a subtle colour-coding is preferred. Manufactured from high-quality cross-linked polyolefin (or equivalent heat-shrink material), the tubing offers reliable electrical insulation, mechanical protection and environmental sealing when applied over large cable bundles, splices, terminations or wiring harnesses.

Key Features:

• Nominal inner diameter: ~20 mm before shrinking — adequate to slide over larger cables, bundles or harnesses, then shrink to fit tightly.

• Colour: Grey — suitable for neutral colour-coding, panel wiring aesthetics, or where visual neutrality is required.

• Roll length: 100 metres — cost-efficient for moderate to large installation runs or stock.

• Material & performance: Polyolefin heat-shrink tubing is widely used for its excellent insulation, mechanical durability, wide operating temperature range and good chemical/abrasion resistance. 

• Shrink behaviour: Upon application of heat, the tubing contracts radially (and with only minor longitudinal shrink) to conform tightly around the underlying component. 

• Applications: Ideal for insulating and protecting large-diameter cable bundles, harness systems, splices, terminations in industrial control panels, automation equipment, telecommunications, infrastructure or any installation where ~20 mm coverage is needed and grey colour is suitable.

• Installation guidance: Slide the tubing onto the cable or bundle before making the connection/splice. After assembly, position the tubing over the splice/joint/bundle and apply uniform heat (e.g., hot-air gun) until the tubing shrinks and conforms. Avoid direct flame contact and ensure even heat distribution. 

• Benefits:

  • Provides neat, professional looking cable runs and finishing

  • Colour coding (grey) supports system organisation and visual consistency

  • Reliable insulation and protection from abrasion, dust, moisture and other environmental factors

  • Bulk roll format (100 m) supports efficient installation and stock management
