Abstract: To restrict a fitting length of an inserting side tubular member such as a corrugate tube into a receiving side tubular member having a flexible portion such as a rubber boot when the inserting and receiving side tubular members are connected. Projections 16 are formed on the inner surface of a fitting end portion 13. When a corrugate tube 20 is fitted into the fitting end portion 13, a leading end 20A thereof comes into contact with the projections 16, thereby restricting any further insertion of the corrugate tube 20. This prevents the entry of the corrugate tube 20 into the flexible portion 12. Accordingly, there is no likelihood that the smooth deformation of the flexible portion 12 is hindered by the entry of the corrugate tube 20 into the flexible portion 12. Further, since there is no need for a consideration as to an excessive insertion of the corrugate tube 20, the connection can easily be performed.

Abstract: FIG. 2A shows an alignment and sealing arrangement for connecting two non-gender opposed conduit parts (20) and (20'). Seal (22) is captured by two opposed seal protrusions (20C) and (20C') residing on conduit part's end. Bore (18A) of alignment element (18) closely receives opposed alignment protrusions located on conduit parts' end. The alignment protrusions are substantially referenced to their respective passageways. Axial force is applied to displace opposed conduit parts toward one another to cause seal protrusions to compress seal, drawing conduit parts' passageways (20E) and (20E') into an aligned relation, and reducing adjacent mating faces into approximate flush relation with one intersection (30). This coupling has one seal removed from direct contact with media, eliminates any appreciable media entrapment space, and desirably reduces flow disturbance along passageways of conduits.

Abstract: A secondary connector block of the type that is used to reinforce a port through a thin wall so that a mating primary connector block which has a bolt hole offset to the side of a refrigerant line can be used to connect the line concentrically to the port. The secondary connector block consists of a completely cylindrical base with an intermediate annular groove circling its outer surface. The base can be turned on a lathe, since it is completely symmetrical about its axis. The base is first welded concentrically to the port, which is easily done, since no part of the base overhangs the surface of the wall. The side lobe which contains the bolt hole that aligns with the primary block is attached later by a pair of bendable legs that are formed around and into the groove. The legs may be wide enough to fit very tightly into the groove, in which case the side lobe is first turned to the orientation that aligns the bolt holes.
