Abstract: A hydraulic hose end expansion chamber preferably includes a tube, a first end plate, a second end plate, a threaded nipple, an o-ring and a drain screw. The threaded nipple is attached to the first end plate. The threaded nipple is threadably engaged with a threaded hole in a female hydraulic quick disconnect coupler. The first end plate is attached to a first end of the tube. A threaded hole is formed through the second end plate to threadably receive the drain screw. The o-ring is pushed on to the threaded shaft. The second end plate is attached to a second end of the tube. An L-shaped handle is preferably attached to the second end of the tube. A second embodiment of the hydraulic hose end expansion chamber includes a compression spring with a piston. A third embodiment of the hydraulic hose end expansion chamber includes a nitrogen filled bladder.
