A lubricant supply device for a linear guide apparatus is configured to include an end cap 5, and a container 7 retaining lubricant and disposed adjacent to the end cap 5. The end cap 5 is formed with a through-hole 16 extending toward the container 7 from a direction change path 5a. The container 7 is formed with an aperture communicating with the through-hole 16 of the end cap 5. The lubricant is supplied into the direction change path 5a via the aperture of the container 7 and the through-hole 16 of the end cap 5. The slider can be thereby lubricated while preventing damage to a rolling element and the direction change path of the end cap.

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.
