FLEXIBLE JOINT AND ITS ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide a flexible joint excellent in flexibility and chemical resistance and the like although a flexible joint having certain degree of flexibility is proposed so far, while utilizing chemical resistance of PTFE (polytetrafluoroethylene). SOLUTION: A side wall of the cylindrical flexible joint 1 is formed of a laminated sheet 18 (a thickness of 0.1 to 6 mm) of an oriented porous PTFE film 12 and a crushed dense PTFE layer 11 having a thickness less than 50μm.
