5 m heat-shrink tubing, 25.4 mm to 12.7 mm, blue, 2:1 – Offgridtec cable insulation

The 5-meter dispenser box from Offgridtec (MPN: 000591) contains blue heat-shrink tubing for insulating and protecting cables, wires, and large-diameter electrical connections. Thanks to its 2:1 shrink ratio, the inner diameter reduces from 25.4 mm to 12.7 mm when heated, fitting snugly around the respective cable. The convenient dispenser box allows for clean removal and flexible cutting to the desired length.

Heat-shrink tubing for large cable diameters and long-lasting cable protection

• Shrink ratio 2:1 (25.4 mm to 12.7 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
• Protects 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

Reliable Protection for Cables and Connections

When heated, the heat-shrink tubing contracts evenly and securely encloses cables or connection points. This reliably insulates electrical connections while protecting them from moisture, dust, UV radiation, and corrosion. The flame-retardant material is 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 comparable hot-air tool. It can be easily cut to the required length prior to installation.
