10 m Heat-Shrink Tubing, 2.4 mm to 1.2 mm, Red, 2:1 – Offgridtec Cable Insulation

The 10-meter dispenser box from Offgridtec (MPN: 000561) contains red 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 2.4 mm to 1.2 mm when heated, fitting snugly around the respective cable. The convenient dispenser box allows for clean removal and custom cutting to the required length. The technical specifications correspond to those listed in the Offgridtec data sheet.

Durable heat-shrink tubing for cable insulation and electrical connections

• Shrink ratio 2:1 (2.4 mm to 1.2 mm)
• 10 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
• Red version for clear identification of electrical wires

Typical applications

• The heat-shrink tubing is suitable for, among other things:
• Cable insulation
• Repairing damaged cable insulation
• Protection of 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

Permanent protection against external influences

When heated, the tubing shrinks evenly and securely encloses 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.
