摘要： An inner ring 4 of a pipe joint 1 includes a cylindrical body portion 5 having a communication hole 5a for providing communication between flow passage holes 2c and 8a of a joint body 2 and a tube 8, and an annular primary sealing portion 11 projecting from a radially inner side of an axially outer end portion of the body portion 5 toward an axially outer side and to be press-fitted into an annular primary sealing groove 2d formed on the joint body 2. The primary sealing portion 11 is formed so as to be tapered from an axially inner end thereof toward an axially outer end thereof in an axial cross-sectional view, and has a flat surface 11c extending from a radially outer end 11b of the axially outer end thereof toward the radially inner side.

摘要： An antistatic cover which, when the cover covers an insulating resin-made tube, can enhance the certainty of preventing the tube from being electrically charged, and can facilitate attachment to and detachment from the tube. The tubular cover body, is divided in a circumferential direction to form first and second divided portions. The cover body is elastically deformed such that the first and second divided portions separate from each other, and allow the tube to pass through between the first and second divided portions. The cover body has a plurality of first cutaway portions, which pass through at least one of the first and second divided portions in a radial direction of the cover body, and is configured such that, when the cover body is fitted onto the tube, a part of the tube can be exposed through the plurality of first cutaway portions.

摘要： A sleeve, a cylindrical member for connecting a tube to a tubular body of a fitting, includes a first peripheral wall end portion facing a peripheral wall end portion of the tubular body, and a second peripheral wall end portion pressed into an open end of the tube. The first peripheral wall end portion includes either an annular protrusion or groove. The annular protrusion is pressed into an annular groove in the peripheral wall end portion of the tubular body. The annular groove allows an annular protrusion axially projecting from the peripheral wall end portion of the tubular body to be pressed thereinto. The second peripheral wall end portion includes a bulge portion to expand the diameter of the open end of the tube. An outer periphery of the first peripheral wall end portion includes a flange to axially face the peripheral wall end portion of the tubular body.

摘要： A resin joint includes a joint body having a flow path, sleeves, and union nuts that fix tubes to the joint body. The joint body has a body portion with a curved inner peripheral surface and a straight portion protruding from an end portion of the body portion. The straight portion has outer and inner cylindrical portions radially arranged inside the outer cylindrical portion. An end portion of the inner cylindrical portion is positioned closer to the body portion than is an end portion of the outer cylindrical portion. A groove portion extending parallel with the outer and inner cylindrical portions in an axial direction is formed between an inner peripheral surface of the outer cylindrical portion and an outer peripheral surface of the inner cylindrical portion. The tube is fixed to the joint body such that a press-fit portion of the sleeve is press-fitted in the groove portion.
