    Abstract: A reduced resistance bead seal is integrally formed on a mounting surface 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.

    Abstract translation: 减少的电阻珠密封件一体地形成在两个可匹配地接合的构件的安装表面上,以在两个构件之间存在任何偏心或角度变化的情况下在两个构件之间形成无泄漏的密封。 在一个实施例中,减小阻力珠形成在中空流体导管的倒立的端部的内锥形凸缘上。 胎圈呈现可变形表面,因为配件促使导管的扩口端与接收器中的锥形座接合,其中管道的扩口端与锥形座之间存在偏心或角度方差。 使用独特的方法和独特的成形工具在导管的端部的扩口处同时形成管道的扩口端中的减小阻力珠。
