Abstract
A crown-type probe seal for a female hydraulic coupling member has one or more pressure-energized seals for sealing between the probe seal and the body of the coupling member which retains the probe seal. The generally ring-shaped probe seal has an annular fluid chamber in at least one end of the body of the seal. Hydraulic fluid under pressure may enter the annular fluid chamber and exert a generally radial force in response to a pressure differential. This radial force can act to increase the sealing effectiveness of the probe seal to the body of the female coupling member having such a probe seal.
