It is disclosed an annular seal ring adapted for use in conduit connectors. The seal ring includes an inner sealing portion and an outer sealing portion. The sealing portions are disconnected from each other allowing them to move completely freely relative to each other during operation.

A seal assembly for an HVAC system includes a first block having a first aperture and a first sealing surface, a second block having a second aperture and a second sealing, and a conduit having a tube portion with an axially extending aperture and a flange extending radially outwardly from an end of the tube portion. The tube portion is disposed within the first aperture of the first block and the flange is disposed between the first sealing surface of the first block and the second sealing surface of the second block and is configured to deform when compressed therebetween. The seal assembly further includes an insert providing fluid communication between the aperture of the tube portion and the second aperture of the second block. A first end of the insert is received in the aperture of the tube portion of the conduit.

Clamping system for connecting two tubes having protruding clamping surfaces. The system comprises a collar having a strip able to cooperate with the clamping surfaces. The strip has a first and a second flank between which an inner recess able to receive the clamping surfaces is delimited. The system has at least one retaining clip having a cross-member which extends across the inner recess, a first and a second wing which extend radially outwardly relative to the cross-member by covering the flanks and a first and a second retaining configuration each having at least one retaining lug. The cross-member is able to be deformed to penetrate into the inner recess.

A fluidic connection device (10) for a fluid circuit, in particular of a vehicle, this device comprising: a first pipe (12), a tubular end-piece engaged in the first pipe (12), a first flange (16) mounted around the first pipe (12), a second flange (18) mounted around the end-piece, at least one element (20) for attaching the first and second flanges (16, 18) one against the other, and a non-return insert valve (100) mounted within the first pipe (12).

An industrial process field device includes a pressure sensor, and a housing containing the pressure sensor. The housing includes a base having a base interface and a first base process opening. A flange is attached to the base and includes a flange interface having a first flange process opening. A pressure at the first flange process opening is communicated to the pressure sensor through the first base process opening. A first gasket process opening of a gasket is aligned with the first base process opening and the first flange process opening. A first surface of the gasket engages the base interface, and a second surface of the gasket engages the flange interface. A dielectric insulation system includes at least one dielectric layer that insulates the housing from electrical currents conducted through the flange. Each dielectric layer includes a layer of ceramic material, an anodized layer, or a plastic overmold.

A clamping apparatus connecting tube flanges, includes first and second bracing devices. The first bracing device connects first and second mounting devices and has a partially circular shape with a first inner and a first outer wall. The second bracing device connects first and second connecting devices. The first bracing device inner wall has a first recess. The first bracing device outer wall is configured to contact the second bracing device which is configured to contact the first bracing device outer wall to apply substantially radial force on that first outer wall. The first recess shape is configured to substantially convert the radial force applied to the first bracing device outer wall into an axial force inside the first inner wall. The first and second mounting devices each comprise at least two attachment devices connecting the first and second connecting devices of the second bracing device.

A connection assembly between two portions of a line including an inner conduit for transporting a cryogenic fluid, the assembly including two flanges which are respectively arranged at the ends of the line portions and which are configured to be held in contact with one another by virtue of a fixing arrangement. The contact zone between the two flanges includes at least two grooves for positioning seals and at least one conduit opening out, for the one part, between the two seals and, for the other part, into an expansion chamber for the cryogenic fluid. The expansion chamber is arranged in one, or in the vicinity of one, of the first connection flange and the second connection flange. The expansion chamber includes a detector for detecting the presence of the cryogenic fluid in the expansion chamber or a recess configured for the installation of such a detector.

A joint seal system and method may include a seal and a band. The seal may be positioned between abutting flanges of two adjacent duct sections. A band may be positioned over the two flanges and the flange interface. The joint seal system and method may be configured to mitigate and/or eliminate leakage of pressure, flue gases, condensate, and/or any other fluid, gas, and/or vapor between abutting flanges of duct sections at a flange interface.

A flexible hose end fitting assembly includes a first portion defining a first fluid passageway and having a first end configured for coupling to a fluid conduit, a second portion defining a second fluid passageway and having a first end configured for coupling to a second end of the first portion and a second end configured for securely affixed to a flexible hose. A gasket is disposed in a groove formed in an interface between the first portion and the first end of the second portion of the assembly, and the first portion and the first end of the second portion of the assembly are securely fastened together by a plurality of threaded fasteners to form a continuous fluid passageway between the fluid conduit and the flexible hose. A flexible hose end fitting assembly includes a first portion defining a first fluid passageway and having a first end configured for coupling to a fluid conduit, a second portion defining a second fluid passageway and having a first end configured for coupling to a second end of the first portion and a second end configured for securely affixed to a flexible hose. A gasket is disposed in a groove formed in an interface between the first portion and the first end of the second portion of the assembly, and the first portion and the first end of the second portion of the assembly are securely fastened together by a plurality of threaded fasteners to form a continuous fluid passageway between the fluid conduit and the flexible hose.
