Product Description
Cold Shrink Tube Coax Connector Sealing Kits CST12 Series


CST12 series provide the correct Cold Shrink Tube or the correct Cold Shrink Tube and special foam to make the installation of coax connector seals easy. The installation does not require tooling, and the quality of the installation is less installer dependent.
The main application is the sealing of coax connectors used in the wireless communication antenna market. These mainly outside installed connectors require an extra sealing. 
Technical Information

The outer Cold Shrink Tube is made from UV resistant EPDM or Silicone rubber material to provide an excellent seal on the connector. In cases where the different coax cable diameter can not be covered with the tube application range, a special foam is used to increase the smallest cable diameter to fit the shrink performance of the Cold Shrink tube.
