Quickly becoming the standard in satellite and cable television installation, compression connectors provide reliable connections and resistance to moisture. Bright nickel finish stands up to harsh environments and reduces the effects of oxidation. Internal O-rings and a tapered plastic ferrule provide a barrier to moisture migration under the cable jacket that will damage the cable. An O-ring in the nut prevents moisture migration through the threads. Easy installation with the 3-in-1 compression tool #38011.
