PIPE COUPLING AND PACKING

PROBLEM TO BE SOLVED: To provide a pipe coupling capable of coping with cases in the same shape, even when there is a difference in an outer diameter of a pipe. SOLUTION: This pipe coupling has a body part 1 having a hole part capable of inserting an end part of the pipe 70 in a larger diameter than...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a pipe coupling capable of coping with cases in the same shape, even when there is a difference in an outer diameter of a pipe. SOLUTION: This pipe coupling has a body part 1 having a hole part capable of inserting an end part of the pipe 70 in a larger diameter than the outer diameter of the pipe 70, and annular packing 20 interposed between an inner peripheral surface of the hole part of the body part 1 and an outer peripheral surface of the pipe 70 inserted into the body part 1, and is characterized in that the packing 20 has at least one recessed part 30a continuing in the peripheral direction, and is constituted so as to change a width dimension in the radial direction by being deformed so that a distance between adjacent two surfaces changes via the recessed part 30a.
