5 m Heat-Shrink Tubing, 9.5 mm to 4.8 mm, Blue, 2:1 – Offgridtec Cable Insulation

The 5-meter dispenser box from Offgridtec (MPN: 000582) contains blue heat-shrink tubing for insulating and protecting cables, wires, and electrical connections. The 2:1 shrink ratio reduces the inner diameter from 9.5 mm to 4.8 mm when heated, ensuring a precise, reliable fit. Thanks to the convenient dispenser box, the heat-shrink tubing can be neatly removed and easily cut to the desired length.

Versatile heat-shrink tubing for cable insulation and long-lasting protection

• Shrink ratio 2:1 (9.5 mm to 4.8 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 handling
• Protection against moisture, UV radiation, corrosion, and mechanical stress
• Can be cut to the desired length
• Blue version for marking electrical wires

Typical applications

• Cable insulation
• Repair of damaged cable insulation
• Protection of soldered and crimped connections
• Photovoltaic and solar systems
• RV and Caravan Electrical Systems
• Automotive and motorcycle electrical systems
• Model making
• Industry and control panel construction
• DIY and workshop applications

Effective Protection for Cables and Connections

When heated, the tubing shrinks evenly and forms a 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 temperatures as low as 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 comparable hot-air tool. It can be flexibly cut to the desired length prior to installation.
