Quickly becoming the standard in satellite and cable television installation, our compression connectors provide reliable connections with a high resistance to moisture. High frequency, these are compatible with digital cable and satellite. The bright nickel finish withstands harsh environments, and reduces the effects of oxidation. An o-ring in the nut and a tapered plastic ferrule provide a barrier to moisture migration through the threads and under the cable jacket that would otherwise damage the cable. Use item #38011, our 3-in-1 compression tool, for easy installation.
