A dry disconnect coupling for connecting one fluid conduit to another fluid conduit to form a continuous flow path, the coupling including a receptacle and a coupler, each being secured to a respective conduit or container. The receptacle and the coupler are secured and locked together to provide a connection for transfer of fluids. A poppet valve is provided and seated in each of the receptacle and the coupler for sealing a respective flow passageway therein when the coupling is uncoupled. The receptacle poppet valve and the coupler poppet valve can be unseated to permit flow of fluid through the coupling when the coupling is coupled and locked. The poppet valve of the receptacle has resilient annular seal member in its poppet sealing surface. The coupler body and poppet and the receptacle body and poppet are provided with a resilient annular seal member at their interfaces; the coupler poppet is self-aligning, and the arrangement of the seal member and the geometry of the coupler body and poppet and the receptacle body and poppet are such that a small interface between the two poppets is provided, so that only a minimal volume of fluid remains in the coupling after uncoupling.
