An end cap for an open end of a hydraulic fitting having a peripheral flange can be provided by a threaded ring and a threaded insert. The threaded insert can be rotatably engaged with the threaded ring to move axially back and forth. The threaded insert has a forward end face which can engage the open end of the hydraulic fitting to close the hydraulic fitting end or to couple with the hydraulic fitting. The threaded ring includes a locking member to embrace and engage the peripheral flange. An optional locking device can be provided to lock the end cap on to the hydraulic fitting. The end cap can be used to prevent loss of oil from the hydraulic fitting during service of equipment on which the hydraulic fitting is utilized, and for other purposes. |
