10 m Heat-Shrink Tubing, 3.2 mm to 1.6 mm, Blue, 2:1 – Offgridtec Cable Insulation

The 10-meter dispenser box from Offgridtec (MPN: 000567) contains blue heat-shrink tubing and is suitable for electrical insulation as well as for protecting cables, wires, and connection points. Due to its 2:1 shrink ratio, the inner diameter reduces from 3.2 mm to 1.6 mm when heated, causing the tubing to fit snugly around the cable. It is delivered in a convenient dispenser box that makes it easy to remove the tubing cleanly and cut it to size.

Versatile heat-shrink tubing for insulation and cable protection

• Shrink ratio 2:1 (3.2 mm to 1.6 mm)
• 10 m tube length in a convenient dispenser box
• 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
• Sold by the meter; can be cut to any 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 against external influences

When heated, the tubing shrinks evenly and fits snugly around cables or connection points. This reliably insulates exposed areas 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 heat-shrink tubing begins to shrink at temperatures as low as approximately 70 °C. A temperature of at least 100 °C is recommended for complete shrinkage. This allows the tubing to be applied quickly and easily using a heat gun or a suitable hot-air tool. It can be flexibly cut to the required length prior to installation.
