ABSTRACT:
A kit of component parts for forming at least first and second grease sampling devices includes a number of housings, piston bodies, and piston shafts. A first grease sampling device has a piston movable in the barrel and vent holes that resists the buildup of back pressure when the device is filled with a grease sample. A second grease sampling device includes a push rod extending from the piston that enables a representative grease sample to be obtained from a bearing, gear or other lubricated part that is not easily accessible.
