DEXLAN kuitujatkos suoja 40 mm (395413)

This splice protector stands out with its integrated stainless steel strength member, which reinforces the splice point against bending and tension—a detail often missing in basic heat-shrink sleeves. The 40 mm length is matched to standard fusion splice trays, and the transparent polyolefin tube lets you visually confirm the splice is centered before shrinking.

Highlights

• Stainless steel strength member adds mechanical stability to the splice
• Hot-melt adhesive seals the splice against moisture and dust
• Transparent tube allows visual alignment check before shrinking
• Shrink ratio approx. 2:1 for a tight, uniform fit

In daily use

Slide the protector over the bare fusion splice, position it centrally, and apply heat from 90°C to 120°C. The outer tube shrinks down to 3.5 mm diameter while the inner adhesive flows to encapsulate the fiber. Once cooled, the splice is protected from mechanical stress, humidity, and dust, and can be safely placed in splice trays or closures. The protector works with both single-mode and multi-mode fibers.
