ABSTRACT:
A device connects two components in a manner that allows fluid to flow therebetween and allows one component to rotate with respect to the other. The device has a first coupling with first and second fluid passages extending between opposite ends. A collar is attached to one end of the first coupling and includes a first flange extending radially inward. A tubular fitting has a second flange extending radially outward and in-between the first flange and the first coupling. A first seal is compressed between the first and second flanges when pressurized fluid flows through the first coupling. A second coupling is attached to the tubular fitting and has third and fourth passages. A tubular second seal is sealingly received within and connects the first and third passages.
