Manufacturing a collapse resistant hose arrangement includes fabricating a hose around a flexible conduit having a spiral-wound interlock configuration. Fabricating the hose includes extruding a first polymer layer over the flexible conduit; cooling the first polymer layer; extruding a second polymer layer over the first polymer layer after the first polymer layer has cooled to form a core tube around the flexible conduit; and extruding an outer sheath around the core tube. In certain examples, the first polymer layer is sufficiently thin as to not flow into an interfering relationship with the spiral-wound interlock configuration of the flexible conduit during cooling.

A pivotable hose connector having a connector, an attachment assembly and a clamping nut. The connector housing has a crimp sleeve portion having a threaded outer surface and a lower housing cavity. The attachment assembly has a hose insertion member and a tubular coupling assembly. The hose insertion member has a hose barb and a central bore, and is positioned within the connector housing so that the crimp sleeve portion surrounds the hose barb. The body end is positioned within the lower housing cavity. The tubular coupling assembly is in rotative sealed engagement relative to each of the connector housing and the hose insertion member, and includes a tubular extension having an internal bore portion in fluid communication with the central bore. The clamping nut is threadedly engageable with the outer surface, and includes a bore extending therethrough that corresponds to the central bore.

A connect structure for semiconductor processing equipment includes a housing configured to mate a deformable pipe with a non-deformable pipe. The housing includes a first annular sidewall to receive the deformable pipe and a second annular sidewall defining a first thread structure. An annular bead is connected to the first annular sidewall to flexibly deform the deformable pipe toward the non-deformable pipe structure when the first thread structure rotatably engages a second thread structure of the non-deformable pipe.

A universal device for replacing worn or lacerated parts of connecting conduits between components of climate control or cooling or hydraulic systems for the connection between components of new climate control or cooling or hydraulic systems, comprising a metal sleeve provided at an end of a coupling for pipes joined to it in a sealed fashion, designed to be fitted and clamped on a stretch of rigid pipe joined to a connector for connection of the connecting conduit to a component, and at the other end of a fitting for connection with a flexible hose designed to replace the worn or lacerated connecting conduit. The sleeve can be rectilinear or curved with angle of approximately 45 or approximately 90. The previous device is prepared in a kit according to different sizes.

A tubular hose stem with a flange, a first left hand threaded section on the outer surface of the stem generally adjacent the flange, a first JIC/swivel nut over the flange having an inner diameter smaller than the outer diameter of the flange, a second lock nut threadably engaged to the hose stem on a second left threaded section adjacent the JIC nut, a conical washer fixedly secured around the hose stem between the first and second threaded sections, an O-ring positioned adjacent the washer opposite the left side of the washer; and a ferrule having a first end fixedly threaded to the hose stem and having a second end larger in diameter than the stem. The lock nut may have knurled surfaces and the inner diameter of the ferrule and outer diameter of the stem may have circumferential raised ribs to engage hosing.

Provided is a flexible hose assembly having a flexible tube for conveying fuel through a first fuel passage formed interiorly of the flexible tube and a flexible hose surrounding the flexible tube and forming therewith a second fuel passage. The flexible tube provides internal support for the flexible hose while also allowing for flow of fuel through the second fuel passage and the fuel passages are separate from one another along a length of the flexible hose assembly. When one of the fuel passages is in a low flow or no flow condition, fuel flowing through the other of the fuel passages acts to cool the fuel passage in the low flow or no flow condition to prevent stagnant fuel in the passage from heating up and coking.

A breech lock coupling comprising a stem receivable in a hose, a ferrule configured to receive the stem and hose, a connector, the ferrule comprising a plurality of ferrule lugs on an inner surface, each ferrule lug separated from an adjacent ferrule lug by a ferrule lug gap, the connector comprising a plurality of connector lugs on an outer surface, each connector lug separated from an adjacent connector lug by a connector lug gap, each ferrule lug gap arranged to receive a connector lug and each connector lug gap arranged to receive a ferrule lug upon engagement of the ferrule with the connector, each connector lug axially alignable with a ferrule lug upon rotation (R) of the connector within the ferrule, the connector engages a stem end, a fastener for fixing a connector position relative to the ferrule.

The present disclosure provides an apparatus having a base with at least one guide formed along a length thereof. A fitting clamp and a tube clamp are coupled to the base and spaced apart from one another. A drive mechanism is operable for moving at least one clamp relative to the other clamp along the guide of the base so as to slidingly assemble a tube and fitting together.

A multilayer hose includes a liner layer and an outer sleeve circumferentially surrounding the liner layer. The liner layer has an inner circumferential surface defining a tubular flowthrough passage extending in an axial direction through the multilayer hose. The liner layer comprises ethylene chlorotrifluoroethylene. The inner circumferential surface of the liner layer may be electrically conductive and may have a surface resistivity of less than or equal to about 110.sup.6 Ohms per square at 20 degrees Celsius, or the inner circumferential surface of the liner layer may be electrically insulating and may have a surface resistivity of greater than 110.sup.6 Ohms per square at 20 degrees Celsius. The outer sleeve defines an outer circumferential surface of the multilayer hose and comprises a reinforcing material.

A hose construction having a coupling secured to an end of a hose, with the coupling including a tubular insert formed with a polymer mixed with chopped reinforcement fiber and including first and second ends, with the first end being inserted in the hose, and the second end including a connector interface. A tubular metallic ferrule is connected to the tubular insert adjacent to the second end in order to form an annular hose receiving space between an outer surface of the insert and an inner surface of the ferrule. The end of the hose is received in the annular hose receiving space, and the ferrule is deformed inwardly against the hose to form a secure connection. The tubular insert formed of a non-metallic material has high strength and is resistant to corrosion due to contact with the materials being transported.
