Abstract: The present invention provides a socket and a pipe joint which facilitate coupling and uncoupling of the socket and a plug and which can prevent the plug from jumping out of the socket in the uncoupling. In a socket 10 of the present invention, fluid in a built-in plug part 22 is released to the outside via communication holes 40 of a second base portion 18 and a through hole 51 of a third base portion 19 in a semi-inserted state. Accordingly, the pressure in a hole portion 34 does not become excessively high and an engaged part 42 is not unexpectedly pushed upward. Thus, an engagement portion 38 and a second engaged portion 26 can surely engage with each other. Hence, the plug 12 can be prevented from jumping out toward the front end side in the semi-inserted state.

Abstract: The present invention provides a socket compatible with multiple types of plugs having front end portions varying in length and a pipe connector having this socket. The socket 10 of the present invention mainly includes a base portion 18, first steel balls 22 and second steel balls 24 housed in housing holes of the base portion 18, an outer support portion 26 supporting the first steel balls 22 and the like from the outer side, and an inner support portion 25 supporting the first steel balls 22 and the like from the inner side. The socket 10 includes first housing holes 50 in which the first steel balls 22 are housed and second housing holes 52 in which the second steel balls 24 are housed and which are longer than the first housing holes 50 in an axial direction.

Abstract: A fluid fitting of an embodiment mainly includes a socket part, a spherical valve inserted in the socket part, and a plug part configured to be inserted at a tip portion thereof into the spherical valve. Moreover, the plug part is fixed in the direction of turn by engaging an expanded-diameter portion of the plug part with a recess of the socket part. Thus, the plug part is prevented from being detached from the socket part while the fluid fitting is in use.

Abstract: A fluid fitting of an embodiment mainly includes: a first connecting part connected to a supply path through which compressed air is supplied; a second connecting part connected to a use path through which the compressed air is used; a rotary fitting body by which the first connecting part and the second connecting part are rotatably connected; and a third connecting part rotatably connected to the second connecting part. Further, the rotary fitting body is capable of rotating such that the first connecting part can bend at an angle of 90 degrees with respect to the second connecting part.
