ABSTRACT:
An oil sampling apparatus for taking samples from either pressurized or non-pressurized oil sources is provided. The oil sampling apparatus includes a body configured to define a conduit therethrough, a vacuum passageway defined to extend through the body in fluid communication with the conduit, and a pressurized oil passageway defined to extend through the body in fluid communication with the conduit. The body further defines a rigid tube having a tube interior connectable between a source of pressurized oil and the pressurized oil passageway. A sample bottle is positionable adjacent to the body in fluid tight communication with the conduit and a manually operated vacuum pump is attached in fluid communication to the vacuum passageway to allow oil to be drawn from a non-pressurized oil source, through the conduit, and into the sample bottle. Oil from pressurized sources can be collected by allowing a needle positioned in the tube interior to trigger release of pressurized oil from the source of pressurized oil when connected to the source of pressurized oil.
