ABSTRACT:
A seal for a fitting adapter for fluid couplings wherein a coupling probe is received within a recess within the other coupling half and the seal prevents the creation of subatmospheric pressures during withdrawal of the probe. The seal includes a lip or flapper valve component which establishes sealing during coupling pressurization, and permits atmospheric pressure to flow around the lip during coupling disconnection.
