摘要：A grease gun coupler for delivering grease from a tube of a grease gun to agrease fitting is provided. Insertion of a grease fitting in the coupler pushes in a piston,allows a bias or an operator to push an outer sleeve towards the grease fitting, whichbiases the ball bearings inwards, thus securing the grease fitting in the coupler.Retraction of the outer sleeve releases the ball bearings, thus allowing another bias topush back the piston and expel the grease fitting.
