Abstract: A fluid coupling has a male member having a generally rigid base and an attached, relatively resilient face with a first fluid flow path opening from the resilient face. A female member of the coupling has a generally cylindrical receptacle with an opening for admitting the male member and a second fluid flow path for communication with the first fluid flow path in the male member when the male member is inserted into and rotated in the receptacle. The male and female members have cooperating cam surfaces opposite the opening into the fluid flow path in the member for urging the members together with a force directed at the opening. The force compresses the resilient face of the male member against the receptacle to seal the fluid flow paths about the openings. The preferred embodiment is a T coupling in which the male member has a third fluid flow path extending through it and in communication with the first fluid flow path.
