A grease cap having an outer ring portion which engages with an exterior surface of a grease cartridge, and an inner ring portion which engages with an interior surface of the grease cartridge. The outer and inner rings define a U-shaped circumferential groove for receiving the grease cartridge. The outer ring portion can include vents formed as indentations in the inner sidewall thereof. The vents can allow air to escape during installation of the grease cap.

A plug for retaining a filter screen in a fluid port of a servovalve, comprises an annular body, the annular body comprising: opposed first and second axial end surfaces, a radially inner surface extending between the first and second axial end surfaces, a radially outer surface extending between the first and second axial end surfaces and at least one recess formed in the radially inner surface for receiving a tool for removing the plug from the port. A tool for removing the plug comprises a pair of handles pivotally mounted to one another about a pivot, each handle having a plug gripping portion extending therefrom beyond the pivot, each plug gripping portion comprising an outwardly projecting tooth for engaging in the recess of the plug when the plug gripping portions are moved apart by operation of the handles.

A grease gun sleeve that comprises of an elongated semicircular body that has a first and second end, the first end has a flattened neck and the second a semicircular neck. A nylon or polyester stretchable material covers the elongated semicircular body to form a tube sleeve. The tube sleeve forms a first and a second end. The tube sleeve has closing means sewn, heat pressed or molded on the ends. In preferred embodiments, the closing means will be an elastic or rubber band that is placed adjacent to the ends. The grease gun sleeve has two pull tabs attached to the ends of the tube sleeve that allow the grease gun sleeve to be manipulated when placed on the hose of a grease gun. The grease gun sleeve is used by first placing the semicircular neck end over the nozzle and hose of a grease gun, then sliding the grease gun sleeve on the hose in a first direction so that the sleeve is fully mounted on the hose, this is the uncovered position, then skidding the grease gun sleeve in a second direction until the flattened neck is past the nozzle so that the closing means rests within the groove of the present invention, the covered position.
