Abstract
A tube coupling assembly has independent primary and secondary sealing elements. The coupling assembly includes first and second coupling members which define a fluid passage therethrough. The coupling members are arranged relative to one another so as to define a contact seal therebetween. An annular fluid path extends between the contact seal and the fluid passage, and a seal element, such as an O-ring is disposed in said fluid path. Accordingly, the seal element is always in contact with, and thus cooled by, the fluid in the passage. The coupling assembly also includes a coupling nut disposed over a portion of one of the coupling members and threadingly engaging the other coupling member to retain the coupling members together. A plurality of resilient fingers is provided on one of the coupling members, and a plurality of grooves is formed in the coupling nut. The fingers are received in the grooves so as to oppose rotational displacement of the coupling nut from its assembled position.
