Heat Shrinkable Tube – Φ3 mm Blue, 200 m Roll

Detailed Description:
This is a high-quality blue-coloured heat-shrinkable tube with an original internal diameter of Φ3 mm and supplied in a continuous 200-metre roll, making it ideal for bulk wiring, harness production, service stocks or major cable runs. It is manufactured from cross-linked polyolefin (or equivalent) and offers reliable insulation, abrasion resistance and environmental protection when installed over wires, cable joints, splices or terminals. Highlights and features:

• Nominal diameter: Φ3 mm (prior to shrinking) – suitable to fit wires, cables or bundle diameters around ~3 mm outer diameter (verify fit).

• Colour: Blue – useful for colour-coding, circuit identification, visual differentiation of wiring bundles or aesthetic match.

• Roll length: 200 metres – economical for large scale installations or service inventory.

• Material & construction: Typically cross-linked polyolefin heat-shrink tubing, providing stable shrink performance and insulating properties. The general purpose of heat-shrink tubing is insulation and protection of wires, connectors and joints. 

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

• Applications: Ideal for wiring harnesses, control panels, cable bundles, telecommunications, automotive, industrial installations, home wiring, repairs and service jobs where colour coding is beneficial.

• Installation notes: Slide tubing over the joint or cable section before connection; then after wiring is complete, slide into position and apply uniform heat (e.g., hot air gun) until the tubing contracts snugly around the joint. Avoid direct flame contact to prevent damage.

• Benefits: Ensures neat, professional cable bundling; offers mechanical protection; colour-coding (blue) helps with circuit identification; bulk 200 m roll gives cost-efficiency and fewer roll changes.
