This black heat shrinkable tubing (type H-2Z-4.0/2.0) is made from polyethylene and shrinks from a 4.00mm diameter to 2.00mm when heat is applied. It serves to mark, insulate, and mechanically protect cables and wire terminations across industrial, commercial, and domestic applications.

The polyethylene material resists heat and varying weather conditions without deforming, making it a practical choice for repair work, spare-part replacement, and general wiring maintenance.

Key Features

• Polyethylene construction for resistance to heat and environmental variation
• 2:1 shrink ratio — contracts from 4.00mm to 2.00mm inner diameter
