F Male Universal Compression Seal, Jar, 10PK (0406-00CSTP) The GEM by Triplett 0406-00CSTP's compression seal design was created to develop a line of products that would be used by the installer of CATV, IP CCTV, and Home Theater Systems, using one assembly procedure and one crimp tool for F, RCA, and BNC connectors. This connector will cost more but there will never be a service call as a result of this connector. The 0406-00CSTP employs a 360 degree plastic insert completely capturing the cable components to the inside walls of the connector. The plastic compression sleeve is tapered so that it will fill all available space to produce a cable retention that is far superior to any and all connector designs.
