Silicone Cold Shrink Tube with Mastic



BMC-SD Series is silicone rubber cold shrink tubings with build-in mastic. It is designed for splice & termination weatherproofing wireless cell towers and CATV networking.

The tubings are open-ended, silicone rubber, tubular sleeves, which are factory expanded and assembled onto a removable supporting plastic core. Each rubber assembly is supplied for field installation in the pre-stretched condition. As the core is unwound, the insulating sleeve shrinks to form a tight seal. The mastic at both ends provides excellent moisture-tight seal.
