Heat Shrinkable Tube – Φ4 mm Brown, 200 m Roll

Detailed Description:
This heat-shrinkable tube features a nominal internal diameter of Φ4 mm (4 mm) before shrinking, supplied in a continuous 200-metre roll — ideal for bulk wiring harness production, large-scale installations or service stock. The tube is made from cross-linked polyolefin (or equivalent) which offers strong insulation, abrasion resistance and reliable performance when installed over wires, cable joints, splices or connectors. Key features:

• Nominal inner diameter: ~4 mm (before shrink) — slides easily over typical wires/cables, then shrinks to provide a snug protective covering.

• Colour: Brown — useful for colour-coding wiring bundles, matching enclosure aesthetics or standardising installation.

• Roll length: 200 metres — economical for large runs, installation stock or service use.

• Material & performance: Polyolefin-based heat shrink tubing offers a wide operating range (e.g., –55 °C to +135 °C typical) and good electrical and chemical resistance.

• Shrink ratio & behaviour: Many polyolefin tubing variants offer shrink ratios of 2:1, 3:1 or 4:1 (i.e., they shrink to half, one-third or one-quarter of their original diameter) when properly heated. 

• Applications: Suitable for wiring harnesses, cable bundling, general electrical insulation, colour-coded wiring, industrial, automotive or control panel use — especially where a brown-coloured finish is preferred.

• Installation tips: Slide the un-shrunk tubing over the joint or cable section before connection; after wiring is complete, position the tubing and apply uniform heat (for example a hot-air gun) until it fully contracts and conforms around the substrate. Avoid direct flame heating to prevent damage.

• Benefits: Provides neat, professional finishing of wire terminations; helps insulate and protect from mechanical abrasion, moisture, contaminants; the bulk roll format (200 m) reduces roll-changes and lowers install cost.
