Silicone cold shrink tube with built-in mastics for telecom
Product Description:
Silicone Cold Shrink Tube with built-in mastic is a pre-expanded, ready-to-install insulating and sealing tube designed for reliable environmental sealing and electrical insulation of power cables and accessories. Manufactured from high-performance silicone rubber and integrated with a factory-applied sealing mastic, the tube shrinks automatically after removal of the inner core, providing a tight, uniform seal without the need for heat or special tools.
This product is ideal for applications requiring superior moisture sealing, electrical insulation, and long-term reliability in harsh environments.
