摘要： A resin-made pipe joint with enhanced sealing property between a joint body and sleeve. A sealing portion which seals between an inner circumferential surface of an inserting portion of a sleeve and an outer circumferential surface of an inner cylinder portion is formed by press-inserting an inserting portion into a groove portion of the joint body. When the inserting portion is press-inserted into the groove portion, a space is formed between a body cylinder portion located opposite to an opening portion of the groove portion in the axial direction, and the projection end of the inserting portion. After completing press insertion of the inserting portion into the groove portion, in a section including axis of the inner cylinder portion, a region in the outer circumferential surface of the inner cylinder portion facing the space forms an angle of 5° to 15° to the axis of the inner cylinder portion.

摘要： A pipe-connecting device includes: an inner ring having: an outer circumferential portion having a tip-contracted outer-circumferential flared surface that is to be press-inserted into an end portion of a tube to flare the tube, and an inner circumferential portion constituting a fluid transfer path; a pipe joint body that has a tubular screwing portion having an external thread; and a union nut having an internal thread that is screwed with the external thread. The inner ring including the tube is inserted into the tubular screwing portion, and the tip-contracted outer-circumferential flared surface is pressed through the tube by a pressing portion of the union nut. The pressing portion of the union nut is formed into an inclined inner circumferential surface that is inclined in the same direction as the tip-contracted outer-circumferential flared surface with respect to the axis of the tubular screwing portion.

摘要： A fitting assembly for fluid device is provided, which includes a first port, a second port, a first annular member, a second annular member, and a connector. The first port is annular and installed at a first fluid device to be connected with its first fluid channel. The second port is annular and installed at a second fluid device to be connected with its second fluid channel. The first annular member is installed at the first port and has a first coupler. The second annular member is installed at the second port and has a second coupler to be coupled with the first coupler to fix the second annular member to the first annular member. The connector is installed between the first port and the second port and seals gaps between the connector and the first and second ports.

摘要： A structure for mounting a gasket on a block includes a block with a fluid channel and an annular gasket surrounding an opening of the fluid channel. The block has an annular inner wall and an annular outer wall. The annular inner wall is made of resin and located radially outside the opening of the fluid channel. The annular outer wall is made of resin and located radially outside the annular inner wall. The annular inner wall and the annular outer wall allow an axial side of the gasket to be press-fitted therebetween and are elastically deformable in their radial directions.

摘要： A structure of a resin-made pipe joint includes a sleeve which is press-insertable from one axial side into one longitudinal end portion of a flexible tube to flare the one longitudinal end portion to hold the flared state, a joint body which is couplable to the sleeve, and a union nut which is fastenable to the joint body to hold a state where the sleeve press-inserted into the one longitudinal end portion is coupled to the joint body. The sleeve has a taper-like first outer circumferential surface, a second outer circumferential surface having an outer diameter that is smaller than a maximum outer diameter of the first outer circumferential surface, and an annular step portion which is an annular step portion that is disposed between the first outer circumferential surface and the second outer circumferential surface and comprises an edge portion on a side of the first outer circumferential surface.

摘要： In a pipe-connecting device having a pipe joint body, a union nut, and an inner ring that is to be press-inserted into an end of a tube, a seal element portion is formed in a basal end portion of the inner ring, and a seal forming portion of the pipe joint body is formed. The pipe-connecting device has a configuration where, in an assembled state, the seal element portion and the seal forming portion are pressed against each other, and a diameter-contracted tube portion, which is in a tube end portion, and which is fitted onto a base-contracted diameter-contracted outer circumferential surface, and a tubular screwing portion are pressed against each other by a contact pressure that is lower than a contact pressure between the seal element portion and the seal forming portion, or separated from each other.

摘要： A gasket-mounting structure includes a mounting member and a gasket. The mounting member includes a first base, an outer sleeve protruding from the first base, an inner sleeve protruding from the first base in the same direction of the outer sleeve radially inside the outer sleeve, and a groove surrounded by the first base, the outer sleeve, and the inner sleeve. The gasket includes an annular second base, an annular outer protrusion extending from the second base to be pressed in the groove, and an annular inner protrusion extending from the second base to be axially pressed on the inner sleeve radially inside the outer protrusion such that the inner sleeve is radially placed between the outer protrusion and the inner protrusion.

摘要： A resin tube fitting prevents backwaters between its body and inner ring. The fitting includes a body, an inner ring, and a union nut. The body has main, outer, and inner sleeves, and a groove. The inner ring has a cylinder, an insert, and outer and inner protrusions. The union nut has a body and a pressing member. The inner sleeve has a through hole serving as a channel. The inner protrusion extends from the cylinder to an axial direction to contact the inner sleeve. The inner protrusion has a through hole serving as another channel connected with the inner sleeve's channel. The tip of the inner protrusion has an inner diameter not less than the minimum inner diameter of the inner sleeve. An inner peripheral surface is located at the inner periphery of the inner protrusion and causes it to reduce in inner diameter toward another axial direction.

摘要： A resin tube fitting has: a body with an outer sleeve; an inner ring including an insert portion insertable into the outer sleeve to contact the outer sleeve radially, and a press-in portion configured to be pressed into a longitudinal end of the tube; and a union nut configured to be engageable with the body. The body and the inner ring are made of resin, which has a property of contracting in response to change in ambient temperature. A radial contraction rate of the outer sleeve of the body is designed to be higher by 0.09% or more than that of the insert portion of the inner ring.
