This heat shrinkable tubing is made from polyethylene and shrinks from 8mm to 4mm in diameter when heat is applied. Each piece is one metre long and is supplied in black. It provides mechanical protection, insulation, and cable marking across repair and maintenance tasks.

The material offers high tensile strength and resistance to heat and changing weather conditions. It prevents conductor deformation and extends cable service life in exposed or demanding environments.

Key Features

• Shrink ratio of two-to-one: shrinks from 8mm to 4mm when heated
• Polyethylene construction for durability and electrical insulation
• Black colour for cable identification or neutral colour coding
• One-metre piece for flexible cutting to the required length
• Effective for outdoor use: resists heat and weather variation

Product Benefits

• Two-to-one shrink ratio creates a tight, conforming seal over joins and repairs
• Polyethylene resists deformation, protecting the underlying conductor long-term
• Black colour aids cable identification and suits discreet installations
• One-metre length gives flexibility to cut multiple shorter sections from a single piece
• Suitable for industry, commerce, and domestic wiring maintenance tasks
