Connector assemblies for holding two tubes together and methods of use are described. The connector assemblies have an inner bolt, a split outer bolt comprising at least two outer bolt sections and a clamp bolt. The clamp bolt holds the outer bolt sections together to form the split outer bolt and the inner bolt is screwed into the outer bolt to enclose the two tube ends.

A face seal fitting operable to join first and second conduits together and to provide a face seal, the face seal fitting comprising a body comprising a fluid passageway, and a coupling portion having an end defining a mating face; a gland comprising a fluid passageway, and an end having a mating face operable to be seated against the mating face of the body; a polyimide sealing component configured to be situated between the body and the gland; and a compression nut fittable over the gland and coupleable to the body, the compression nut being operable, upon torqueing to achieve a threshold compression load, to cause the mating face of the gland to seat against the mating face of the body, and to compress and elastically deform the polyimide sealing component to be flush with the mating faces of the body and the gland to form a face seal.

A refrigerator includes a water system and a valve. The water system is configured to direct water to a dispenser or an ice maker. The valve includes a valve body, an inlet port, and a clutch. The valve is configured to connect the water system to a water source. The inlet port is configured to receive a tube to establish fluid communication with the water source and to engage a nut to secure the tube to the inlet port. The clutch is disposed between the inlet port and the valve body and is configured to slip in response to an applied torque to the inlet port exceeding a threshold.

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.

The present disclosure provides a pipe coupling that includes a coupling body, a first pack joint nut, and first and second sleeves. The coupling body is made of a first metal material and the first pack joint nut is made of a second metal material. The first pack joint nut is configured to receive a portion of a first pipe. The pipe is made of a dissimilar metal material to the first and second metal materials of the coupling body and the first pack joint nut, respectively. The first sleeve is configured to line at least a portion of an inner periphery of the coupling body. The second sleeve is configured to line at least a portion of an inner periphery of the first pack joint nut. The first and second sleeves are made of non-metallic materials, and serve as physical non-metallic barriers between the first/second metal materials of the coupling/first pack joint nut, and the dissimilar metal material of the first pipe.

A pipeline fitting, which comprises connection support elements and can be easily installed and removed, for indirectly connecting a first pipe connection to a second pipe connection. Compression joints between the first and second connection support elements of the pipeline fitting and a first and a second compression joint flange on a first and a second compression joint connector can be produced in the longitudinal direction of the pipeline fitting. This is achieved in that the pipeline fitting features a vibration compensator with an elastic bellows, as well as a respective tubular fitting section and a sealing ring integrally formed thereon to both sides of the bellows in the longitudinal direction, wherein the sealing ring can be clamped between a connecting flange of the connection support element and the compression joint flange of the compression joint connector.

A hammer union includes a male sub, a threaded female sub, a threaded union nut disposed around abutting ends of the threaded female sub and the male sub, the abutting ends of the threaded female sub and the male sub include contact surfaces perpendicular to a longitudinal axis of the hammer union, and an outermost diameter of the perpendicular contact surfaces and a minor thread diameter of the female sub are equidistant from a longitudinal axis of the hammer union. A method of assembling a hammer union includes inserting a plurality of load segments between a threaded union nut and a male sub, threadedly engaging internal threads of the threaded union nut with external threads of a female sub, and engaging flat contact surfaces of abutting ends of the male sub and the female sub.

An enhanced union connection for connecting tubular members together. The enhanced union connection may include a male end member, a female end member, a wing nut, and nut retaining segments. The union connection

A gasket includes a thick portion providing a first face seal and a thin portion providing a second face seal. A fluid coupling has an annular gasket housing recess that includes a wide portion for housing the thick portion of the gasket and a narrow portion for housing the thin portion of the gasket.

A screw connection device for connecting two pipes with flared ends, comprises a screw, a nut and a spacer. The nut has a front end aperture from which an accommodating space extends to a rear end aperture in a rear end wall. A surface of the nut in the accommodating space has a threaded section which extends toward the rear end wall which has a flange face in the accommodating space. In a pre-installed state, the spacer and a first pipe end with a first flare are accommodated in the nut, such that the spacer is held undetachable between the first flare and the internal thread. A second pipe end with a second flare can be held in the accommodating space by the screw, threaded into the nut such that the second flare is pressed against a sealing surface of the spacer and the spacer is pressed with a further sealing surface against the first flare.
