Heat Shrinkable Tube – Φ20 mm Brown, 100 m Roll

Detailed Description:
This heat-shrinkable tubing features a nominal undeployed inner diameter of approximately 20 mm (Φ20 mm) before shrink, and is supplied in a continuous 100-metre roll—perfect for larger cable bundles, harness runs, or industrial installations requiring bulk length. The brown colour option provides a convenient colour-coding or aesthetic match for wiring systems. Manufactured from high-quality cross-linked polyolefin (or equivalent heat-shrink material), the tubing provides robust electrical insulation, mechanical and environmental protection when applied over cables, splices, connectors, or bundles.

Key FEATURES

• Nominal inner diameter: ~20 mm (before shrink) — suitable for sliding over larger cables/bundles and then shrinking to conform snugly.

• Colour: Brown — useful for circuit identification, matching panel or harness colour schemes, or coding installations.

• Roll length: 100 metres — economical for moderate-to-large runs, stock inventory, or service usage.

• Material & performance: Polyolefin heat-shrink tubing is widely utilized because it offers excellent all-purpose insulation, flame retardancy, flexibility, and durability. 

  • Typical operating temperature range: approx. –55 °C to +135 °C.

  • Shrink ratios commonly 2:1, 3:1 or more — meaning tubing will contract significantly in diameter when heated. 

• Applications: Ideal for insulating and protecting large-diameter cable harnesses and bundles, cable terminations, industrial control wiring, automotive/transport harnesses, telecommunication or infrastructure runs where 20 mm coverage is required.

• Installation Notes: Slide the tubing onto the cable or bundle before making the splice or connection. After positioning over the required section, apply uniform heat (e.g., hot-air gun) until the tubing shrinks and conforms. Avoid direct flame contact and ensure even heating.

• Benefits:

  • Professional finishing of cable bundles and installations

  • Colour-coding (brown) enhances wiring system organisation and aesthetics

  • Provides strong insulation and protection against abrasion, moisture, dust and environmental contaminants

  • Convenient 100-metre roll format enhances productivity and reduces roll changes
