Abstract: A ferrule subassembly for a conduit fitting includes first and second ferrules. The first female includes a front body portion defining a forward tapered surface, a rear body portion defining an interior camming surface, and a retaining extension joined with the rear body portion radially outward of the camming surface and extending axially rearward and radially inward from the inner axial portion. The second ferrule includes a front portion having a tapered forward contact surface adjacent the first ferrule camming surface, an outer radial portion extending axially rearward of the forward contact surface, and a recessed portion axially rearward of the outer radial portion. An end portion of the retaining extension is received in the recessed portion of the second female to retain the ferrule with the first ferrule as a discontinuous subassembly.

Abstract: A method for treating a workpiece made from a self-passivating metal and having a Beilby layer is disclosed. The method comprises exposing the workpiece to the vapors produced by heating a reagent having a guanidine [HNC(NH2)2] moiety and complexed with HCl to activate the workpiece for low temperature interstitial surface hardening.

Abstract: A fitting includes a first threaded fitting component, a second threaded fitting component that threadably joins with the first fitting component to produce relative axial stroke between the first and second fitting components, and a conduit gripping device receivable between the first and second fitting component. When the fitting is pulled-up on a conduit, a radially outward facing tapered first annular surface of the first fitting component axially engages a radially inward facing tapered second annular surface of the second fitting component. At least one of the first and second annular surfaces includes a recess extending from an inner diameter to an outer diameter of the corresponding annular surface, the recess defining a leak detection port in fluid communication with the fitting interior volume when the first annular surface is in axial engagement with the second annular surface.

Abstract: A push to connect fitting includes a body member adapted to receive a conduit end, a conduit comprising a first end that can be axially inserted into the body member and a conduit gripping device attached to an exterior surface of the conduit, and a retainer that retains the conduit in place when said conduit is fully inserted into the body member. Additional embodiments include providing a seal with the fitting that seals the exterior surface of the conduit, an optional load retaining sleeve for the conduit gripping device, and an optional gimbal. The push to connect aspect may be realized in the form of a single action unthreaded mechanical connection.

Abstract: In a method of assembling a conduit fitting, a conduit fitting is provided, including a first coupling member, a second coupling member, an internal conduit gripping device disposed between said first coupling member and said second coupling member, and an external deformable structure. The first coupling member is pulled up with the second coupling member on an end portion of a conduit to engage the external deformable structure with an external surface of one of the first and second coupling members. After engaging the external deformable structure with the external surface of one of the first and second coupling members, the first coupling member is further pulled up with the second coupling member to axially compress the external deformable structure, until an amount of torque required to continue pulling up the first coupling member increases to a predetermined torque. The predetermined torque corresponds to an initial pulled-up position in which the conduit gripping device grips and seals the conduit.

Abstract: A push to connect fitting assembly includes first and second fitting components joined to define an interior cavity, a seal device, a retainer, and a biasing member. The seal device is disposed in the interior cavity, and forms a seal between one of the first and second fitting components and an outer surface of a conduit end when the conduit end is inserted into the outboard end of the first fitting component. The retainer is assembled with at least one of the first and second fitting components, and includes a gripping portion that grips the inserted conduit end. The biasing member is axially disposed between the retainer and the seal device, the biasing member applying a first axial load to the retainer to produce a gripping force between the gripping portion and the inserted conduit end.

Abstract: A conduit fitting of the type having first and second threaded fitting components and at least one conduit gripping device, further includes a stroke limiting member that allows the fitting to be pulled up by applying a predetermined torque. In one embodiment, the stroke limiting member may be a non-integral torque collar. Alternatively, the fitting may also be pulled up by turns or may have an integral torque collar. In still another embodiment, a stroke limiting member is provided that may be used to enable a fitting that is designed to be pulled up by turns to also be pulled up by torque. In other embodiments, the non-integral torque collar may be installed onto one of the fitting components, and then deformed so as to prevent or make it more difficult to remove the torque collar after installation onto the fitting component.
