A DRIPLESS COUPLER Abstract of the Disclosure A dripless coupler containing a female and a male coupler, the female coupler retained within a housing. The female coupler includes a receptacle enclosing a cavity having an inlet port, an outlet port and an open bore located at one end thereof. Positioned between the receptacle and the open bore is a movable seat which mates with a flat smooth end surface of the main poppet valve which is retained within the cavity. The main poppet valve is normally biased to a closed position against the movable seat. Insertable into the open bore of the female coupler is the male coupler which includes a receptacle enclosing a cavity with an inlet opening. Positioned within the inlet opening is a movable check valve having a flat outer end surface which is mateable with the end surface of the main poppet valve. When the male and female end surfaces join, a flush surface results which prevents the leakage of hydraulic fluid during the uncoupling operation.
