An annular sealing ring housing has a distal end surface with a channel therein, and a sealing ring insert is disposed in the channel, the sealing ring insert including a sealing ring compressed within a second band to maintain the integrity of the sealing ring. The mating ring faces the sealing ring to prevent fluid from escaping therebetween.
