摘要： In order to maintain airtightness by a ferrule even by use of a general-purpose tool and to be capable of releasing airtightness by the ferrule if necessary, a pipe joint (Ja) includes a ferrule (33) receiving an axial pressing force from a fixing member (66a) screwed in a clamping direction thereby to airtightly seal a gap between an inner periphery of the joint body (16) and an outer periphery of a pipe (P) when the fixing member (66a) is rotated in a clamping direction to be screwed in, a loosening male thread (68) formed on an outer periphery of the fixing member (66a) and threaded in a direction opposed to a direction in which the joint body (16) and the fixing member (66a) are threaded, a loosening tool (130) screwable into the loosening male thread (68), and a pressure receiving portion (39) abutting against the loosening tool (130) thereby to prevent further screw-in when the loosening tool (130) is screwed into the loosening male thread (68) and rotated in the direction opposed to the clamping direction of the fixing member (66a).

摘要： In order to improve the reliability of sealing performance, a pipe joint (Ja) includes a cylindrical clamping member (32) screwed into a joint body (16), a ferrule (33) receiving an axial pressing force from the clamping member (32) screwed in a clamping direction, thereby airtightly sealing a gap between an inner periphery of the joint body (16) and an outer periphery of a pipe (P), a cylindrical fixing member (66a) constructing the clamping member (32) and abutting against the ferrule (33) to apply a pressing force to the ferrule (33), a clamping nut (36) constructing the clamping member (32) and having an outer periphery formed with a non-circular fitting portion (48) and receiving a screw-in force in the clamping direction, thereby imparting to the fixing member (66a) a pressing force to the ferrule (33) side, and a locking unit (41) preventing the fixing member (66a) from displacement in a direction such that the ferrule (33) is released from the pressing force applied by the fixing member (66a).
