Coupling device for tubular members |
摘要 |
A coupling device includes a coupling body and a collar adapted to engage a tubular member in a fluid tight seal. The coupling device includes axially spaced front and back ferrules which engage during mounting to provide a plurality of seals intermediate the ferrules and the tubular member as well as the coupling body. The back ferrule includes a generally cylindrical or tubular wall that is elastically/plastically deformed to an arcuate shape to enhance the maintenance of the seals. |
