Abstract: A coupling system that forms a moisture resistant shield around connectable elements comprising a male element containing female connection points inserted into a female element containing male connection points. These made from rigid and thermoplastic materials. This system has a series of rings on the female element and grooves on the male element. These grooves mate to form a first moisture barrier and a rigid lip on the male element circumferentially surrounding the female connection points, presses into a flexible face containing the male connection points on the female element to form yet another moisture barrier. This system can be easily be connected, disconnected and reconnected a plurality of times and yet the highly moisture resistant seal is repeated. It finds good use in communications or electrical connections among others.
