Heat Shrinkable Moulded Shapes 
Fibre Optics Closure - INSULTUBE commercial
Insultube-Commercial (GSF) is heat shrinkable tubing, used in the installation of Fibre Optic Closure. These tubes are designed to insulate & seal the inlet of Cable to the base of Fibre Optic Closure.
It is manufactured from high quality cross linked polyolefin material.
Features & benefits :
- Excellent resistance to weathering, Moisture, Contamination and adverse environmental conditions.
- Hot melt adhesive provide perfect environmental seal on cable sheath.
- Excellent resistance to UV rays, Ozone, Chemicals & Solvents.
- Lightweight and Flexible.
- Provides mechanical strain relief.
- Easily re-enterable.
- Meets IP 68 (Ingress Protection)
