Heat shrink tube DeLOCK Fiber optic splice protection 86839

The DeLOCK heat shrink tube for fiber optic splice protection (model 86839) is a transparent 60 mm sleeve designed to protect fiber splice joints from mechanical damage and environmental influences. Sold in a pack of 10 pieces, this splice protection shrinks under heat to fully enclose the fiber and improve resistance to high temperatures while maintaining optical continuity.

Advantages

The transparent material allows visual inspection of the splice after heat shrink, and the 60 mm length covers typical splice areas. Heat-activated shrinking creates a secure, compact seal that reduces the risk of mechanical stress and contamination. Pack of 10 pieces provides multiple uses for installation and maintenance tasks.

Suitable for

• Protection of single fiber optic splice joints
• Telecommunications and networking installations
• Field service and maintenance of fiber links
• Laboratory and workshop splice testing

How to use

Place the heat shrink tube over the aligned splice area before completing the splice. After splicing, slide the tube to fully cover the joint and apply heat evenly until the tube shrinks and conforms tightly around the fiber. Allow to cool before handling to ensure a stable enclosure.

Recommendations

For reliable results, use a calibrated heat source (heat gun or oven) and avoid direct flame. Verify the shrink temperature range compatible with the tube material and ensure the splice is clean and properly aligned before shrinking.
