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.

Conduit fitting with components adapted for facilitating 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 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.

Push to connect conduit fitting with ferrule

A fitting includes first and second threaded fitting components, a conduit gripping device, and a stroke resisting member having a first axial length, the stroke resisting member being disposed between a threaded portion of the first fitting component and a radially extending portion of the second fitting component. The stroke resisting member is axially engaged by the radially extending portion of the second fitting component when the first and second fitting components are joined together to a first relative axial position, such that a tightening torque beyond the first relative axial position is increased by the axial engagement. The stroke resisting member is plastically compressed to a second axial length smaller than the first axial length when the first and second fitting components are joined together to a second relative axial position advanced beyond the first relative axial position.
