摘要： A hydraulic flange connection (10) having a formed tube (12) in physical conjointness with a contoured sleeve member (14), the conjointness including the sleeve member (14) having a cylindrical body bore (24), a cylindrical outer portion (26) tapering at one axial end into a frustoconical portion (30) abutting one bore end (32), the cylindrical outer portion (26) also merging into an annular outer end surface (36) having at least one circular edge (38) defining a bowl-shaped recess (42) with a raised annular inner end surface (46); the tube having a cylindrical portion (13) extending into and through the sleeve member bore (24), a radial flange portion (54) thereof including an axially outwardly-directed, openly curved, circumferential radial groove (60), with an inner surface (56) of the flange portion (54) conforming axially and radially with an abutting complementary surface (43) of the bowl-shaped outer recess (42) in a fully nesting retention relationship. Details of achieving the conjointness between the tube (12) and the sleeve member (14) are also set forth in product-by-process claim recitation.
