摘要： A pipe joint comprises a pair of tubular joint members made of a metal and each having an abutting end face, an annular gasket made of a metal and interposed between the abutting end faces of the respective joint members, a nut joining the joint members together and a retainer holding the gasket to one of the joint members. The joint members are made of stainless steel and silver white. The retainer is made of stainless steel and colored blue so as to be discernible from the joint members. The joint can be checked for the presence of the retainer, accordingly for the presence of the gasket, merely by discerning whether the color seen through an inspection window is blue or silver white.
