An improved liquid infiltration adapting structure for preventing liquid infiltration around a gate valve box. The structure has an annular tube structure that is tapered to more easily receive a mating pipe. The tube structure may also comprise at least one bead for further securing the mating pipe. The adapting structure is also improved by providing a stepped inner flange for ease of installing the structure around the gate valve box.
