Method for improved sealing between members of fastened joint

摘要

In a fastened joint where two or more joint members are secured together, a method for improving the sealing properties of the joint. The method includes the incorporation of one or more depressions into at least one joint surface of the joint members. The depressions are positioned to reduce the tendency of the joint members to transmit clamping forces between non-sealing areas, thereby increasing the magnitude of the clamping forces transmitted through sealing areas and reducing the opportunity for leakage.
