摘要： 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.

摘要： 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.

摘要： A push to connect fitting includes first and second fitting components, a sealing arrangement, a gripping arrangement, and a colleting ring. The first fitting component has an outboard end that is adapted to receive a conduit end. The second fitting component is joined to the first fitting component to define an interior cavity. The sealing arrangement, disposed in the interior cavity, seals one of the first and second fitting components with an outer surface of a conduit end when the conduit end is inserted into the outboard end of the first fitting component. The gripping arrangement is disposed in the interior cavity, and the colleting ring is disposed in the interior cavity and has an inboard end surface engaging an outboard end surface of the gripping arrangement.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
