<p>A fitting capable of facilitating the opening/closing operations of a ball valve and increasing a durability by suppressing the breakage of a tubular seal body at the time of rotation, wherein a socket fluid passage (4) in a socket (1) is formed so as to be opened and closed by the ball valve (5), the tubular seal body (11) for sealing between the ball valve (5) and the inner wall of the socket fluid passage (4) is disposed in the primary fluid passage (4a) of the socket fluid passage (4) in a pressed state against the ball valve (5), the ball valve (5) can be rotated in open state when the socket (1) and a plug (2) are locked by a lock mechanism (16), and a sub valve hole (33) for feeding fluid in the primary fluid passage (4a) to the secondary fluid passage (4b) of the socket fluid passage (4) through the ball valve (5) before the valve hole (7) of the ball valve (5) is opened in the socket fluid passage (4) by the rotation of the ball valve (5) is provided in the ball valve (5).</p> |
