The Grease Gun Stopper is used to stop unwanted grease escaping from a grease gun coupler, when the grease gun is not in use. This is a welcomed improvement over the present situation where there is nothing but a cloth to catch unwanted grease escaping from the coupler. One snaps the plugged grease nipple or facsimile thereof within the grease gun stopper on or off the grease gun coupler.
