    摘要： A coupling comprises a holding member having a U-shaped cross section, and a channel member held by the holding member. The holding member has an upper wall formed with screw bores for use in attaching the holding member to a fluid controller. The channel member comprises a body having an inner channel and fitted in a space between the upper wall of the holding member and a lower wall thereof, a tubular upward projection communicating with the inner channel of the body and having an upper end inserted in a through bore in the upper wall of the holding member to communicate with a downward channel of the fluid controller, and a tubular lateral projection communicating with the inner channel of the body and extending laterally. The upper end of the channel member has an outward flange, and the through bore of the upper wall of the holding member has an inward flange for supporting the flange.

    摘要： A pipe joint comprises a pair of tubular joint members, an annular gasket interposed between abutting end faces of the joint members, and a nut for joining the joint members. A seal projection is formed on the abutting end face of each joint member at a position radially outward of an inner periphery of the end face. When an end of the seal projection is brought into contact with an end face of the gasket by tightening the nut, a clearance is formed between an outer flat portion of the abutting end face of each joint member and the gasket end face opposed thereto. The clearance is greater than a clearance between an inner flat portion of the abutting end face of each joint member and the gasket end face opposed thereto, and is eliminated when the nut is completely tightened up.

    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.
