Abstract: The present invention improves the handling properties of a rubber-only gasket and the affixability thereof to an attachment position. To this end, the provided gasket is: obtained by combining a gasket body of the rubber-only type, and a carrier sheet that comprises a resin film and holds the gasket body in an un-adhered state; and characterized in that the gasket body is provided with an adhesive section or bonding section for adhering or bonding the gasket body to an attachment position when attaching the gasket body to the attachment position. The adhesive section or bonding section is prepared by providing the lateral surface of the gasket body with a projecting section, and coating the surface of the projecting section with an adhesive or bonding agent. The gasket body is to be used as a gasket for a fuel cell to be incorporated into a fuel cell stack.

Abstract: A housing kit (90) includes a housing body (20) and a ventilation member (10). The housing body (20) has a vent hole (21). The ventilation member (10) has a leg portion (26). The leg portion (26) is a portion adapted to be inserted into the vent hole (21). The housing body (20) has an inner peripheral surface (23) that defines the vent hole (21). The inner peripheral surface (23) includes a first rounded segment (23 R1 ), a first straight segment (23 S1 ), a second rounded segment (23 R2 ), and a second straight segment (23 S2 ) that are formed in order from an exterior space (24) side to an interior space (22) side of the housing body (20). The first rounded segment (23 R1 ) and the second rounded segment (23 R2 ) each form a curve convex toward a central axis (O) of the vent hole (21) in a cross section of the housing body (20) including the central axis (O). The first straight segment (23 S1 ) and the second straight segment (23 S2 ) each form a straight line in this cross section.

Abstract: Described is a mobile phase fitting having reduced corrosion and erosion. The fitting includes a coupling body, compression screw, compression member and gasket. The coupling body has a threaded bore at one end, a tapered cavity, a narrow bore and a fluid channel. The compression screw has an axial bore to receive a tube and a threaded outer surface in engagement with the threaded bore of the coupling body. The compression member is disposed in the tapered cavity and has an axial opening to pass the tube and a tapered surface to engage a surface of the tapered cavity. The gasket is disposed in the narrow bore and has one surface in contact with the first internal surface and has a parallel surface to receive an end face of the tube.
