The Max Spare style BA seal is a bonded seal combination of NBR seal ring and a metal back up ring. The NBR seal ring is bonded perfectly to the inner portion of the metal back up ring. When a bolt is tightened with BA seal, the NBR seal ring having a Trapezoidal cross section gets compressed to an extent where the bolt cannot be further tightened due to the metal back up ring. Under such state, the NBR seal ring not only has a preload pressure on the mating surface higher than the pressure being sealed, but also forms the profile of a U’ring to withstand higher pressures.
The BA seal can also be provided in high temperature resistant material on request.
