Figure 110 is recommended for use in piping systems where isolation of electrical current may be required, such as when cathodic protection is applied to a piping system in order to mitigate corrosion. The metallic components are separated by two insulating rings, one of which also functions as a sealing member. Materials used for insulating the connection and the double O-Ring arrangement used for sealing are constructed of high quality materials that are resistant to most of the process fluids and chemicals that are routinely encountered during oil and gas production.
