PIPING MATERIAL CONNECTOR AND PIPING MATERIAL ARRANGEMENT STRUCTURE
To provide a piping material connector which can further surely connect a piping material to a connected body in a cutoff state.SOLUTION: A piping material connector 100 comprises: a connector main body 110; a nut body 120 screwed to a screw part 113 of the connector main body 110; a spacer body 130 externally fit to a cylindrical part 112 of the connector main body 110 between the nut body 120 and a flange part 116 of the connector main body 110, and slidable in an axial direction of the cylindrical part 112; and a cutoff body 140 externally fit to the cylindrical part 112 between the spacer body 130 and the flange part 116, compressed to the axial direction by being pressed by the spacer body 130, and expandable to a radial direction at a cylinder wall 143. The cylinder wall 143 of the cutoff body 140 is composed of a first region 144 formed in a prescribed position in the axial direction, and a second region 145 adjacent to the first region, and the first region 144 is formed so as to be preferentially expanded in a diameter, and deformed with respect to the second region 145 when compressed to the axial direction.SELECTED DRAWING: Figure 3
【課題】より確実に止水状態で配管材を被接続体に接続することができる配管材接続具を提供する。【解決手段】配管材接続具１００は、接続具本体１１０と、接続具本体１１０の螺子部１１３に螺着されるナット体１２０と、該ナット体１２０と接続具本体１１０のフランジ部１１６との間で接続具本体１１０の筒状部１１２に外挿され、筒状部１１２の軸方向にスライド可能なスペーサ体１３０と、該スペーサ体１３０とフランジ部１１６との間で筒状部１１２に外挿され、スペーサ体１３０に押圧されることにより、軸方向に圧縮するとともに径方向に筒壁１４３が膨出可能な止水体１４０と、を備える。止水体１４０の筒壁１４３は、軸方向の所定位置に形成された第１領域１４４と、隣接する第２領域１４５とからなり、第１領域１４４は、軸方向に圧縮されたときに第２領域１４５に対して優先的に拡径変形するように構成されている。【選択図】図３
