Disclosed is a fluid connection system including a sleeve, a pipe and a fluid connector, the fluid connector including at least one rigid body made from a sterilizable biocompatible material, and the pipe including a flexible connection portion made from a sterilizable biocompatible material that is at least partially elastomeric. The fluid connector and the flexible connection portion of the pipe are assembled to one another, with the flexible connection portion of the pipe surrounding the rigid body, and the sleeve being shrunk tightly, but with free movement, on the pipe.

The present invention relates to a method of manufacturing a bifurcated pipe and a bifurcated connector for connecting hoses and a fuel supply hose manufactured using the same, in which connection between a torch and an oxygen tank or a gas tank is facilitated and hoses are prevented from becoming twisted or entangled during a welding or cutting process.

Further, according to the present invention, a single connection hose is prevented from being damaged by sparks, a piece of steel cut off the workpiece, a discarded welding rod, or a sharp cut surface or edge of the workpiece, and a worker is capable of easily recognizing gas leakage and a portion from which gas is leaking, thereby preventing an accident.

Fabrication of formed hoses is provided which include an innermost elastomer layer, a first fiber-reinforcement region, and multiple second fiber-reinforcement regions. The first fiber-reinforcement region has a first fiber-reinforcement density, and is disposed, at least in part, at a bend region of the formed hose, and the multiple second fiber-reinforcement regions have a second fiber-reinforcement density, and are disposed at least at the first and second end regions of the formed hose. The second fiber-reinforcement density is greater than the first fiber-reinforcement density, and results in the first and second ends of the formed hose being less radially-deformable than the bend region of the hose. This facilitates providing a mechanical fluid-tight connection with a hose barb fitting when the formed hose is slid over the hose barb fitting, absent any clamp over the formed hose and hose barb fitting connection.

A quick connector is disclosed comprising a receptacle having first and second channels formed on opposite sides of the exterior of the receptacle. A flange includes a retainer mounting part fixed on a first end of the flange. A first pair of clamping jaws extends from a second end of the flange with each clamping jaw of the first pair of clamping jaws accepted into a respective receptacle first and second channel, clasping the receptacle to the flange. The clamped bracket retainer and receptacle are then guided to have a tube inserted into an interior passage of the receptacle and the bracket retainer is attached to a rigid structure using a fastening arrangement that retains the quick connector receptacle and endform in a connected state.

In order to provide a sealing element which ensures a reliable seal and which can be produced easily and economically, it is proposed that a main body of the sealing element is formed from a partially fluorinated or fully fluorinated thermoplastic material which is injection-moldable.

A rotatable joint includes a body configured for connecting to an external system and provided with an internal hole arranged for being traversed by pressurised fluid, a tubular element on an end of which a hose can be inserted that is sealingly coupled with the joint and provided with a further through hole that defines, together with the internal hole, a longitudinal channel that extends parallel to a longitudinal axis within which the pressurised fluid flows. The joint further includes an annular closing element fixed to the tubular body by a threaded connection and a rotatable coupling arrangement that acts at least in a longitudinal direction to enable mutual rotation between the tubular element and the tubular body.
