ABSTRACT:
A fitting assembly for coupling tubing to a device having a sealing surface is provided. The fitting includes a ferrule for seating against the sealing surface. The ferrule has a head. The ferrule is formed from a first material. A reusable collar having a bevelled rear surface and an inner surface is provided. The inner surface has a ring for gripping the tubing. The collar is formed of a second material that may differ from the first material and may be malleable. A coupler engages the head of the ferrule to push the ferrule against the sealing surface. The coupler has a ramped inner surface for engaging the rear surface to push the collar against the head of the ferrule. The coupler compresses the collar radially to grip the tubing.
