I have used similar stuf for ROV thethers and umbilicals. The thing about screens is that the kit proably dont come with the bits to run it through the splice. if the screen is copper mesh just solder the mesh together end your probably good if the signals running through them are not tcritical for noise. If noise is critial get some coppper mesh on roll and wrap this around the wires before assambling the shell and pouring the potting.
