Probe seal having spring-energized sealing elements for female hydraulic coupling member |
摘要 |
A crown-type probe seal for a female hydraulic coupling member has one or more circumferential, spring-energized seals. One particular preferred seal comprises a closely-wound helical spring which imparts an inwardly-directed radial force to the crown seal. In certain embodiments, the helical spring is substantially encased in a polymer jacket. In yet other embodiments, a liner is interposed between the outer surface of the helical spring and the polymer jacket. An optional, axial extension on at least one end of the crown seal provides a bore liner for a female hydraulic coupling member in which the crown seal is installed.
