Tubo termorretrátil DeLOCK 20890 45 mm x 130 mm 2 unid. preto

DeLOCK cold shrink tube 45 mm x 130 mm, pack of 2, is made of silicone and provides mechanical protection and electrical insulation for cables, tubes and wires. The pre-expanded sleeve is supplied with a removable plastic core so it can be applied without heat; after removing the insert the silicone contracts to form a tight, sealed covering suitable for outdoor use.

Advantages

The silicone construction offers resistance to weathering, UV radiation, ozone, acids and alkalis, ensuring durability in exposed environments. Tool-free shrinking requires no heat source or specialised equipment; installation is quick and safe. The black colour provides discreet protection and the package contains two sleeves for multiple applications.
