Silicone Cold Shrink Tube with Mastic for Better Weatherproofing
Silicone cold shrink tube with mastic built inside is designed for better weatherproofing protection on connections between jumper cable and connector (7-16 DIN, N type or 4.3-10) of wireless equipment, such as RRU, Antenna and Microwave. Comparing with tape sealing protection, cold shrink tube installation is much shorter (15-30 seconds), convenient installation, uniform appearance for acceptance.
Features
» High elastic silicone rubber tube structure with mastic built-in for better weatherproofing protection;
» Stable and long life during operation;
» Fast installation, only 15-30 seconds needed to seal one connection;
» Perfect SWR performance approved by telecom operators;
» Good operating capability under extreme cold and hot condition, anti-UV, anti-ozone;
» Much time and labor cost saving;
