摘要： An inner ring 4 of a pipe joint 1 includes a bulge portion 6 formed at an axially outer end portion thereof so as to project toward a radially outer side, and to be press-fitted into an end portion of a tube 8, and has a fluid flow passage 4a formed on a radially inner side of the bulge portion 6. The bulge portion 6 is formed so as to be tapered from an axially inner side toward an axially outer end thereof in an axial cross-sectional view, and has a flat surface 6e formed at the axially outer end thereof and extending in a radial direction.

摘要： A fitting body includes a tubular end whose outer periphery has an external thread and whose inner periphery has an annular groove or protrusion. A sleeve connects a tube to the tubular end of the fitting body. A union nut includes a first axial end that receives the tube therein and a second axial end to be screwed onto the external thread of the fitting body. The fitting body includes first and second regulating portions extending in directions that intersect an axial direction of the fitting body to contact the union nut being screwed onto the external thread and then sharply raise torque to be transmitted through the union nut to a hand of a worker. When being screwed onto the external thread, the union nut contacts the first regulating portion and subsequently the second regulating portion.

摘要： A method for coupling a tube to a tube fitting includes radially outwardly expanding a tubular compression collar from a constricted state to an expanded state, the compression collar having a throughway extending there through and being made of a resiliently flexible material. An end of the tube is inserted within the throughway of the expanded compression collar, the tube bounding a passage. A tube fitting is inserted within the passage of the tube. The compression collar is allowed to resiliently rebound back towards the constricted state so that the compression collar pushes the tube against the tube fitting.

摘要： A sealed sleeve installed at an insertion coupling portion in a state in which a first pipe and a second pipe are insertion coupled to each other in order to seal couple the first pipe having a first outer diameter and a first inner diameter and the second pipe having a second outer diameter and a second inner diameter larger than the first outer diameter includes: a pillar shaped-main body having a main body central shaft; a through-hole formed using the main body central shaft as a central shaft on the main body and having an inlet as a second pipe side opening in an installation state and an outlet as a first pipe side opening in an installation state, wherein in the through-hole, a pressing portion that applies a sealing pressure to the insertion coupling portion is formed in a portion of an inner wall, and an inner diameter of the pressing portion is smaller than the second outer diameter.

摘要： A fluidic connection assembly and methods for quickly connecting or disconnecting a tube to a port by hand and without the use of tools. A body is adapted to receive a tube therethrough, and may have at least two sides which are hinged. Each of the hinged sides has corresponding latching portions or projections located near a lower end of the body. These projections are adapted to fit into a port or other fitting and be securely held in place. The assembly may include a tube extending through a body and through a spring located between the end of the body and the end of the tube, whereby the spring exerts a force directly or indirectly against the end of the tube and against the body, thus holding the tubing securely and sealingly engaged in the port when the assembly is connected. The body may further comprise an additional body or an adapter, and/or a cap and latch. A second spring may be used to push a projecting member into a groove or notch of an adapter when an end of the adapter is inserted into one end of the latch or the body. The fluidic connection assembly is useful in analytical instrument systems, such as for in vitro applications and/or in high pressure applications, among other things, and may be used in methods for connecting, or disconnecting, tubing or a fluidic connection assembly from a port or other fitting or connection.

摘要： A connecting assembly for operatively and fluidly connecting at least first and second hose segments together. The connecting assembly includes at least one insert portion, and corresponding bulge(s), securing device(s) and fluid passage(s).
The securing device is removably mounted onto and displaceable about a portion of a given length span of the insert portion, and configured for operation between a first release mode, where the securing device being is drawn away from the bulge and thus an extremity of the hosing segment is releasable, and a second connecting mode, where the securing device is removably and selectively displaced over an outward overlapping of the extremity of the hosing segment extending over the bulge, so as to securely maintain said extremity of the hosing segment in place, operatively against the bulge and thus, prevent the first extremity of the first hosing segment from being removed from the bulge. Quick and easy.-

摘要： Disclosed is a pipe coupling module for coupling a distribution pipe and a flexible pipe in a water distribution system. The pipe coupling module includes a pipe branch section diverging from the distribution pipe, a pipe connection socket coupled directly to the pipe branch section, and a pipe joint unit coupling the flexible pipe, wherein the pipe branch section and the pipe connection socket are formed of chlorinated polyvinyl chloride (CPVC), and are joined by means of a solvent cement.

摘要： A pipe/fitting having an end having a modified crimp for securing both flexible ducts and pipes. Specifically, the pipe/fitting includes an end having a series of annularly disposed pipes. The modified crimp includes an outwardly facing channel in the base of the series of crimps configured to secure a flexible duct between the channel and a fastener received in the channel. The end also includes a pipe coupling system at the base of the series of crimps configured to couple a pipe to the conduit.

摘要： A clamp device for a barb member having a barbed region for disposing within an end of a flexible tube having an outer surface. The clamp device includes a flexible member including a body having a plurality of finger members compressible between a first resting position and a second clamping position; at least one of the flexible finger members having a radially inwardly extending tooth; the body having a through bore and an outer surface comprising threads; the flexible member being slidable over the barbed region and the outer surface of the flexible tube; a compression member having a body having a through bore and an inner surface including threads; the compression member being slidable over the flexible member; wherein upon threadingly engaging the compression member with the flexible member, the compression member compresses the finger member against the barb member.
