Metal C-Ring, spring energized for Internal Pressure (MCI-F):

 shaped like MCI, but this ring can handle higher loads, making it suitable for use with rougher mating surfaces. It excels in applications such as pressure vessel closures, manways, hand-holes, steam generators, gasoline/diesel engine fire rings, and exhaust joints. Its the best choice for non-flat mating surfaces. While its primarily designed for internally pressurized joints, it can also be used for externally pressurized joints to prevent the working fluid from entering the seal cavity, albeit at a reduced working pressure rating.
