Heat shrink tube DeLOCK 20858 25 mm x 130 mm black silicone 2 pcs

DeLOCK cold shrink tube 20858 is a black silicone sleeve with an outer diameter of 25 mm and a length of 130 mm supplied as a set of two. Designed for mechanical protection and insulation of cables, wires and tubing, the product provides a sealed cover against moisture and dust without the need for heat during installation.

Advantages

The cold shrink tube installs without tools: remove the inner plastic core and the silicone sleeve contracts to wrap and seal the cable. Made of silicone, the tube offers increased resistance to weathering, acids, alkalis, ozone and UV radiation, making it suitable for outdoor environments.

Suitable for

• Insulating and sealing electrical cable joints
• Protecting exposed wires and small hose connections
• Outdoor cable runs and installations requiring UV and weather resistance

How to use

Slide the cold shrink tube over the cable or joint while the silicone sleeve is held expanded on its removable plastic core. Position the sleeve so it fully covers the area to be protected, then pull out the plastic insert; the silicone will contract and form a tight, insulating and sealing cover around the cable without applying heat or additional tools.

Recommendations

Ensure surfaces are clean and dry before installation for the best seal. Select a tube diameter appropriate for the cable or bundle to allow full contraction and a snug fit. For long-term outdoor use, periodically inspect the silicone for mechanical damage.
