Abstract
A dripless coupling device in which a male unit and a female unit selectively interconnect flow conducting members, a male barrel having a male cylinder disposed therein which is insertable into a female body. The female body is provided with a dial retainer liner adapted to receive a dialer member such that the male cylinder can be selectively rotated by the dialer member to index the cylinder bore of the male cylinder with the male barrel port of the male cylinder and the liner port and the hollow post of the female body. A seal is formed between the female body and the dialer member when the male unit is disconnected and a biasing assembly is provided for biasing the dialer member into sealing engagement with the seal while permitting the dialer member to be retracted upon connection of the male unit to the female unit.
