Abstract: A modular fitting for conduits such as tube and pipe comprises a universal body (12) having at least two selectable configurations and at least one or more connecting parts that when joined with the body form a fitting. The body includes a drive member (24) and a conduit gripping member (28), and in an exemplary embodiment the conduit gripping member may be in the form of a conical spring (28) that grips the conduit (c) when axially compressed during pull-up. The modular design for a fitting facilitates postponement of final fitting configuration and assembly beyond the manufacturing facility to an end user or other location and time.

Abstract: Apparatus and method for mechanically attached connections of conduits may include a conduit gripping member (34), a drive member (36), and a seal member (48), the drive member (36) causing axial movement of the conduit gripping member (34) to indent into an outer surface of the conduit when the assembly is pulled-up, the drive member (36) causing the seal member (48) to form a zero clearance seal at a location that is axially spaced from the conduit gripping member (34). The zero clearance seal may comprise a face seal arrangement including a gasket (48), and the conduit gripping member (34) may be a ferrule, ring or other device that can grip and optionally seal against the conduit outer surface. The assembly may include an optional sensing function for detecting or sensing a characteristic or condition of an assembly component or the fluid or both.
