International Classification:

F16L 25/04
F16L 19/065

US Classification:

2853323, 285354

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 and in another embodiment the stroke limiting member may be two engaging surfaces integrally formed with the fitting components. Alternatively, the fitting may also be pulled up by turns. 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. The stroke limiting member facilitates many remakes of the fitting, including remakes by torque.

US Classification:

285307, 2952503

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.

International Classification:

F16K 1724

US Classification:

137498

Abstract:

A poppet type excess flow valve comprises a body forming a valve chamber having a first portion of a first diameter adjacent a first end and a second portion of a second smaller diameter adjacent second end. A valve seat is located between the first and second portions of the valve chamber. A poppet element is mounted in the valve chamber and includes a first section in the form of a hollow cylindrical body extending into the second portion of the valve chamber and terminating therein in an open end. The outer diameter of the hollow cylindrical body section is only slightly less than the diameter of the second portion of the valve chamber for guided sliding movement therein. The poppet element further includes a second section located in the first portion of the valve chamber and including an end wall carrying a valving surface extending radially outward for cooperation with the valve seat. A compression coil spring maintains the poppet element continually biased under a predetermined force toward the inlet port, and flow passages are formed through the hollow cylindrical body portion of the poppet element at a location closely adjacent the valving surface.

International Classification:

F16L 19/10

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.

International Classification:

F16L 19/065

Abstract:

A preassembly for a conduit fitting includes a fitting nut, a ferrule disposed within the fitting nut, and a retaining feature configured to retain the ferrule with the fitting nut prior to assembly of the fitting nut with a fitting body, such that the ferrule is axially spaced from a drive surface of the fitting nut. When the fitting nut is assembled with a fitting body on a conduit end, axially movement of the ferrule toward the drive surface of the fitting nut causes deformation of the retaining feature to release the ferrule from the fitting nut.

International Classification:

F16L 37/092
F16L 37/23

Abstract:

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.

International Classification:

F16L 19/06
F16L 19/10

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.

International Classification:

F16L 37/092

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.
