Abstract

Abstract Method and apparatus for quickly establishing a seal between two flange members, not in perfect alignment. A floating annular seal ring may be provided in a recess of one of the flange members. A resilient sealing means may be mounted in a groove on the face of the sealing ring towards the other flange member. A sliding resilient sealing means may be provided between the seal ring and the flange member in which the seal ring is mounted. The surface of the seal ring adjacent at least one of the resilient sealing means may be chamfered away from the surface of the flange member toward which it faces so that even though the flange members are not perfectly aligned the resilient sealing means may contact both flange members in sealing engagement. Means are provided for urging the seal ring toward the other flange member. Several means of coupling on flange member to the other are disclosed.
