3M HDT-AN-105/26 Halogen-Free Heavy Wall Heat Shrink Tubing, 105 mm to 26 mm, Black 7000099384

Electrical contractors and maintenance technicians rely on the 3M HDT-AN-105/26 heat shrink tubing to insulate and seal cable joints in industrial environments. This heavy wall tubing shrinks from an expanded diameter of 105 mm down to 26 mm, providing a tight, protective jacket over splices and terminations.

Key specifications

• Expanded diameter: 105 mm
• Recovered diameter: 26 mm
• Material: Cross-linked polyolefin
• Adhesive lined: Yes (thermoplastic adhesive)
• Halogen-free: Yes
• Flame retardant: Yes (self-extinguishing)
• Operating temperature: -55°C to +110°C
• Minimum shrink temperature: 120°C
• Dielectric strength: >20 kV/mm
• UV resistant: Yes
• Colour: Black
• Longitudinal shrinkage: Max. 10%

Why choose it

The 4:1 shrink ratio allows the tubing to slide over large connectors and then recover tightly, while the adhesive lining creates a moisture-resistant seal. Halogen-free construction makes it suitable for use in confined spaces where low smoke and toxicity are required.

Ideal use cases

• Insulating and sealing cable joints in industrial power distribution
• Protecting splices from moisture, corrosion, and mechanical damage
• Repairing damaged cable jackets in harsh environments

Good to know

This tubing meets RoHS compliance requirements. It is supplied in black and is part of the 3M HDT-AN series of heavy wall adhesive-lined heat shrink tubing.
