Our high-ratio medium-wall adhesive-lined tubing provides excellent insulation, sealing, impact and abrasion resistance. It seals, secures and protects electronic and telecom connections and gives excellent mechanical protection to cable joints and terminations. The high shrink
ratio makes it easy to fit irregular shapes and large joints. Suitable for waterproofing light fibre-optic cable and wire joints, sealing and securing the connected parts.
Features:
★ UV resistant
★ Efficient electrical insulation and excellent mechanical protection
★ Minimum full recovery temperature: 120 °C
★ Standard colour: black
Applications: sealing, securing and protecting electronic and telecom connections; excellent mechanical protection for cable joints and terminations; especially suited to waterproofing marine fibre-optic cable and wire joints.
