ABSTRACT:
A reduced resistance bead seal is integrally formed on a mounting surface of one of two matingly engageable members to form a leak-free seal between the two members despite any eccentricity or angular variances between the two members. In one embodiment, the reduced resistance bead is formed on an inner conical flange of an inverted flared end of a hollow fluid conduit. The bead presents a deformable surface as a fitting urges the flared end of the conduit into engagement with a conical seat in a receiver where eccentricity or angular variances exist between the flared end of the conduit and the conical seat. A unique method and a unique forming tool are used to form the reduced resistance bead in the flared end of the conduit simultaneously with the flaring of the end of the conduit.
