PROBLEM TO BE SOLVED: To not only be excellent in processability and reduced in a cost and weight but also excellent in resistance against chlorine and oxygen contained in hot water and steam, have resistance against hydrolysis in hot water, have excellent mechanical strength and shock resistance durable to deformation owing to a water pressure and water hammer phenomenon, and prevent the occurrence of water leakage and improve reliability. SOLUTION: A piping coupling 1 to intercouple pipings through which hot water or steam flows comprises a body 12; and coupling parts 11 and 13 to couple the body 12 to a piping (a header and a piping tube). At least one of the body 12 and the coupling parts 11 and 13 is formed of resin wherein a thermoplastic elastomer is added to polyphenylene sulfide, and the body 12, and the coupling parts 11 and 13 are integrally molded. |
