Abstract
A dry disconnect coupling comprises an adapter connected to a liquid conduit and a coupler connected to another liquid conduit. The adapter and coupler each have poppets which seal passageway outlets thereof when they are disconnected. When connected, means are provided for simultaneously opening the poppets by displacing them with their end faces in contiguous relation. An O-ring, mounted in a groove in the end face of the coupler poppet sealingly engages the end face of the adapter poppet to prevent wetting of the end face surfaces of the poppets and thereby minimize liquid which could be a source of liquid when the coupler is disconnected from the adapter. Six alternate sealing rings, for providing an end face seal, are described.
