ABSTRACT:
An engine or gearbox oil sampling device for use with an engine or gearbox containing lubricating oil. The device includes a hand held container having a flexible tube communicating with its interior. The free end of the tube is provided with a hollow member adapted for entering an engine or crankcase oil access opening. Prior to accessing oil the pressure within the container is reduced below atmospheric pressure by connecting the flexible tube with a vacuum pump through a vacuum pump head which supports a flexible and resilient stopper for sealing the end of the tube opposite the container fluid tight after reducing the pressure therein. The stopper includes a frangible wall ruptured by the hollow tubular member as it enters the oil access opening.
