1. An end cap for closing an open end of a hydraulic line terminated by a hydraulic fitting, the hydraulic fitting comprising a peripheral annular flange projecting laterally from the hydraulic fitting and extending around the open end, the open end being free of threading, wherein the end cap comprises:
(a) a threaded ring threaded about an axis of the threaded ring; (b) a threaded insert in threaded engagement with the threaded ring and movable along the ring axis with respect to the threaded ring in response to rotation of the threaded insert with respect to the threaded ring, the threaded insert comprising a forward end face , the forward end face filling the area of the threaded ring across the ring axis and being engageable with the open end of the hydraulic fitting; and (c) a locking member integral with the threaded ring, the locking member embracing the peripheral annular flange when the end cap closes the open end of the unthreaded hydraulic fitting and having a locking surface engageable with a peripheral flange surface remote from the threaded ring;
wherein the threaded insert is rotatable to bring the threaded insert forward end face into closing engagement with the hydraulic fitting,and wherein the entire end cap is both attachable to the hydraulic fitting to close the open end of the hydraulic line and removable from the hydraulic fitting at the open end of the hydraulic line when attached to the hydraulic fitting without damage to the hydraulic line, end cap, or hydraulic fitting, and without removing the hydraulic fitting from the hydraulic line. |
