iGuard™ flange isolation and sealing systems consist of all the necessary components to seal, electrically isolate, and for cathodic protection (corrosion control) between flanges, from general to severe service applications such as water, wastewater, natural gas, hydrocarbons, caustics, acids, and other aggressive media to 232°C (450°F). Gaskets are available for full face (Type E), raised face (Type F), and ring type joint (RTJ) flanges (Type D), to meet all international piping sizes. iGuard™ gaskets meet AWWA, ANSI, API, DN, JIS, and all other dimensional standards.
