5 m Heat-Shrink Tubing, 19.1 mm to 9.5 mm, Black, 2:1 – Offgridtec Cable Insulation

The 5-meter dispenser box from Offgridtec (MPN: 000590) contains black heat-shrink tubing for electrical insulation and to protect cables, wires, and connection points. Thanks to its 2:1 shrink ratio, the inner diameter reduces from 19.1 mm to 9.5 mm when heated, ensuring a precise fit and a permanently secure covering. The convenient dispenser box allows for clean removal and custom cutting to the desired length.

Durable heat-shrink tubing for cable insulation and reliable protection

• Shrink ratio 2:1 (19.1 mm to 9.5 mm)
• 5 m tube length in a convenient dispenser box
• Suitable for insulating cables and protecting electrical connections
• Flame-retardant and halogen-free material
• Low shrink temperature for easy application
• Protection against moisture, UV radiation, corrosion, and mechanical stress
• Can be cut to the desired length
• Black version for a discreet and professional cable installation

Typical applications

• The heat-shrink tubing is suitable for, among other things:
• Cable insulation
• Repairing damaged cable insulation
• Protecting soldered and crimped connections
• Photovoltaic and solar systems
• RV and trailer electrical systems
• Automotive and motorcycle electrical systems
• Model making
• Industry and control panel construction
• DIY and workshop applications

Reliable protection against external influences

When heated, the heat-shrink tubing forms a uniform, tight seal around cables or connection points. This reliably insulates electrical contacts while protecting them from moisture, dust, UV radiation, and corrosion. The material used is flame-retardant, halogen-free, and free of PBB, PBBO, and PBBE. The lead content is less than 10 ppm, and the cadmium content is less than 5 ppm.

Easy to use

The shrinking process begins at a temperature of approximately 70 °C. A temperature of at least 100 °C is recommended for complete shrinkage. The heat-shrink tubing can be applied quickly and evenly using a heat gun or a suitable hot-air tool. It can be flexibly cut to the desired length prior to installation.
