A fitting includes a first and second threaded fitting component and a conduit gripping device receivable within the first threaded fitting component. A stroke resisting member is integral with the first threaded fitting component and includes a web having a first radial thickness and extending axially inward from the first threaded fitting component to a distal ring portion having a second radial thickness greater than the first radial thickness. A radially extending bearing surface of the distal ring portion axially engages a radially extending portion of the second fitting component when the first and second fitting components are joined together to the first relative axial position. The stroke resisting member resists additional axial stroke of the first and second fitting components, such that a tightening torque beyond the first relative axial position is increased by the axial engagement.

A ferrule subassembly for a conduit fitting includes first and second ferrules. The first ferrule 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 ferrule to retain the second ferrule with the first ferrule as a discontinuous subassembly.

Ferrule assembly for conduit fitting

A hose assembly includes an inner core tube, a metal outer tube, a first coupling member, and a first collar. The first coupling member has an inboard nose portion extending into a first end of the inner core tube. The metal outer tube surrounds the inner core tube and terminates at a first end axially inward of the first end of the inner core tube, with an outer cavity disposed between the inner core tube and the metal outer tube. The first collar has an outboard clamping portion surrounding the nose portion for clamping retention of the first end of the inner core tube therebetween, and an inboard venting portion welded to the first end of the metal outer tube, with the inboard venting portion including a venting port in fluid communication with the outer cavity.

A hose assembly includes an inner core tube, a connector including a stem portion inserted into a distal end of the inner core tube, an outer metal tube substantially coaxial with and surrounding the inner core tube, and a collar substantially coaxial with and surrounding the distal end of the inner core tube. The outer metal tube terminates at a distal end axially inward of the distal end of the inner core tube. The collar includes a flared first end welded to the distal end of the outer metal tube and a second end welded to the connector.

Hybrid hose assembly

A subassembly for a conduit fitting includes a first ferrule and a second ferrule alignable relative to an axis. The first ferrule includes a camming surface at a back portion thereof, and the second ferrule includes a surface that contacts the camming surface when the first ferrule and the second ferrule are axially moved together along the axis. A retaining structure retains the first ferrule and the second ferrule together as a subassembly, and includes a flange extending radially outward and axially rearward from the back portion of the first ferrule to define an outer diameter recess. The flange includes an end portion that extends radially inward to define an inner diameter recess retaining a forward portion of the second ferrule. The outer diameter recess and the inner diameter recess together define a hinge portion of the flange.

A fitting assembly includes a first fitting component having an outboard end that receives the conduit end portion, a second fitting component joined to the first fitting component to define an interior cavity, a seal device disposed in the interior cavity, and a retainer assembled with at least one of the first and second fitting components. The seal device forms a seal between one of the first and second fitting components and an outer surface of a conduit end portion. The retainer includes a gripping portion received in a circumferential groove of the conduit end portion to grip the conduit end portion, and a colleting portion outboard of the gripping portion and configured to apply a colleting force to the outer surface of the conduit end portion at least when an outboard axial load is applied to the conduit.

Single action push to connect conduit fitting

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.

A preassembly for a conduit fitting includes an annular fitting component and a conduit gripping device. The annular fitting component has an interior wall extending along a central axis from an inboard end to an outboard end. The interior wall includes an inboard surface having a first diameter, an outboard surface having a second diameter smaller than the first diameter, and an intermediate surface recessed from the inboard surface by an outward facing inboard radial wall and recessed from the outboard surface by an inward facing outboard radial wall. The conduit gripping device is retained within the annular fitting component and includes a projection extending radially outward of an outer circumferential surface of the conduit gripping device, and axially toward an inboard end of the conduit gripping device, with an end portion of the projection being axially captured between the inboard radial wall and the outboard radial wall.
