This black polyethylene heat-shrink tubing is type H-2Z-12.0/6.0, shrinking from a pre-shrink diameter of 12mm to a post-shrink diameter of 6mm when heated. It is used to insulate, bundle, and protect exposed cable joints, wire terminations, and connector entries.

The polyethylene material offers high tensile strength and resistance to heat and varying weather conditions. It is suited to maintenance tasks in industrial, commercial, and domestic settings, preventing deformation of wire insulation and extending cable service life.

Key Features

• Type H-2Z-12.0/6.0 polyethylene heat-shrink tubing
• Pre-shrink diameter: 12mm; post-shrink diameter: 6mm
• Black colour for cable identification and UV screening
• High-strength polyethylene construction resists heat and weather exposure

Product Benefits

• 2:1 shrink ratio (12mm to 6mm) creates a tight, conforming sleeve around cables and connectors
• Polyethylene material prevents insulation deformation under continuous heat
• Protects wire ends from moisture, abrasion, and mechanical stress in repairs and installations
• Black colour provides consistent visual marking and blocks UV degradation on outdoor cable runs
