Hybrid ferrule

A ferrule for use in a fluid transfer assembly having a fluid conduit and a first fitting mateable with a second fitting, the ferrule removably receivable on the fluid conduit and configured to removably secure the fluid conduit between the first and second fittings, the ferrule comprising:

• (a) a frusto-conical seal portion have a first cylindrical bore sized and configured to slidably receive the fluid conduit made from a predetermined material having a hardness, the seal portion formed from a first material suitable to seal the fluid conduit within the first fitting without substantially deforming the fluid conduit, the first material having a hardness no greater than the hardness of the fluid conduit;
• and
• (b) a frusto-conical collet portion mated with the seal portion and having a second cylindrical bore in substantial alignment with the first cylindrical bore, the collet portion including at least one axial finger that is biased into locking engagement against the fluid conduit when the first fitting is mated with the second fitting, wherein the collet portion is formed from a second material that allows the collet portion to lockingly engage the fluid conduit without substantially deforming the fluid conduit, the second material having a hardness no less than the hardness of the fluid conduit.

A ferrule for use in a fluid transfer assembly having a fluid conduit, the ferrule comprising:

• (a) a frusto-conical seal portion having a tapered end and an enlarged end, the frusto-conical seal portion have a first cylindrical bore sized and configured to slidably receive a fluid conduit made from a predetermined material having a hardness, the seal portion formed from a first material suitable to seal the fluid conduit within a first fitting without substantially deforming the fluid conduit, the first material having a hardness no greater than the hardness of the fluid conduit;
• and
• (b) a collet portion having a second cylindrical bore in substantial alignment with the first cylindrical bore, the collet portion including at least one axial finger extending along the tapered end that is configured to be biased into locking engagement with the fluid conduit, wherein 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, the second material having a hardness no less than the hardness of the fluid conduit.
