Abstract
A ferrule for use in a fluid transfer assembly having a fluid conduit includes a frusto-conical seal portion having a first cylindrical bore sized and configured to slidably receive a fluid conduit. The seal portion is formed from a first material suitable to seal the fluid conduit within a first fitting without substantially deforming the fluid conduit. A frusto-conical collet portion is mated with the seal portion and includes a second cylindrical bore in substantial alignment with the first cylindrical bore. The collet portion includes at least one axial finger extending along the tapered end that is configured to be biased into locking engagement with the fluid conduit. The collet portion is formed from a second material that substantially prevents deformation of the fluid conduit when the finger is biased into locking engagement with the fluid conduit.
