Heat shrink tube DeLOCK 20861 35 mm x 130 mm black silicone 2 pcs

Delock cold shrink tube 20861 is a black silicone sleeve designed to provide mechanical protection and insulation for cables, wires and tubes. The sleeve measures 35 mm in diameter and 130 mm in length and is supplied as a pack of two, offering a weather-resistant protective layer for outdoor and indoor installations.

Advantages

The product features toolless shrinking by removing an internal plastic insert, which allows the silicone tube to contract and form a tight, sealed fit around the cable or joint. Made from silicone, the tube provides increased resistance to weathering, acids, alkalis, ozone and UV radiation, ensuring durable protection without the need for heat or special tools.

Suitable for

• Insulating and protecting electrical cables

Recommendations
