5 m Heat-Shrink Tubing, 25.4 mm to 12.7 mm, Black, 2:1 – Offgridtec Cable Insulation

The 5-meter dispenser box from Offgridtec (MPN: 000595) contains black 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, ensuring a secure, snug fit. The convenient dispenser box allows for clean removal and custom cutting to the desired length.

Durable heat-shrink tubing for large cables and reliable insulation

• Shrink ratio 2:1 (25.4 mm to 12.7 mm)
• 5 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
• Provides reliable protection against moisture, UV radiation, corrosion, and mechanical stress
• Can be cut to any desired length
• Black version for a discreet and professional cable installation

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 Electrical Connections

When heated, the tubing shrinks evenly and forms a tight seal around cables or connection points. This permanently 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 flexibly cut to the desired length prior to installation.
