Abstract: A method for bending metal tubing which minimizes the collapse of a tube wall through lowering material stress achieved by reducing the rate of bending. The method includes the steps of selecting a bend radius less than a standard bend radius, determining a rate of bending of a length of tubing so as to minimize material stress, and bending the tubing at the selected determined rate.

Abstract: A swivelable quick connect assembly for use with tubular conduits is disclosed comprising a housing having an axial bore for receiving one end of the conduit, an elastomeric ring-like seal disposed in the bore for providing a fluid tight seal between confronting portions of the conduit and the housing, an annular bushing is disposed in the bore for positioning the seal and for guiding the one end of the conduit into nesting relationship with the bore, and a retainer detachably secured to the housing and cooperable with an annular projection on the conduit for securing the conduit in its operative position within the bore. The retainer is a one piece metal retainer element which includes at least two circumferentially spaced leg members which extend from an integral collar member at one end thereof. Each of the leg members has a deflectable leg portion which extends from the collar and ends in a first bend defined by an arcuate shape to provide a backstop for securing the retainer element in the connector assembly, and a retaining leg portion which extends from the deflectable leg portion and inclines generally toward the aperture in the collar.

Abstract: An apparatus and a method is disclosed for configuring a spring arm retaining ring which is contained by a groove that is put into a bore, such that the concentricity of the ring to a male part which is installed into the bore is limited to an extent that allows the ring to enter a tapered bore leading to the ring bore, and compresses the outside diameter of the ring. The male part that is installed into the bore includes a configuration which cooperates with the retaining ring, and may or may not be a portion of the part, or assembled to the part. The combination of the ring disclosed and the cooperating portion allows a retaining ring to be installed by pushing the male part, that is to be retained in the bore, into the bore.

Abstract: A quick connect assembly for use with tubular conduits is disclosed as comprising a housing with flange portions which prevent separation of the conduits by abutting with the retaining insert of a retainer element. When desired, the conduits can be separated by depressing surface areas attached to flexion configuration arms thereby providing clearance between the flange portions and the retaining inserts so the retaining element can be pulled away from the housing.

Abstract: A bleed-down connector assembly is described which employs a rotatable cap for controlling the axial movement of the conduit in the connector housing between the sealed and bleed-down positions. The cap is mounted concentrically over the housing for both rotational and axial movement with respect to the connector housing. The cap includes a wall portion which is formed to engage a retainer associated with the connector assembly for retaining or maintaining the conduit in the housing. The housing is formed to provide a ramp of varying axial length and the cap is formed with a plurality of depending spring-like tabs which engage the ramp and limit the axial movement of the cap with respect to the housing.
