A system is provided for detecting the presence of and confirming the correct orientation of an oil seal. The system comprises a sensor orifice, a flow regulator for regulating flow of air to the sensor orifice, a pressure regulator for regulating air pressure to the flow regulator, and an air supply means for supplying air to the pressure regulator. A vent orifice is also provided for allowing air flow to exit from the sensor orifice when the oil seal is incorrectly oriented. The system further comprises an air pressure sensor, whereby when the oil seal is correctly oriented, with its flat side blocking the sensor orifice, a back pressure of air is created in the sensor orifice and the air supply means, the back pressure detectable by the air pressure sensor to confirm presence and correct orientation of the oil seal.

[ What is claimed is:] [1.] A system for detecting the presence of and confirming correct orientation of an oil seal, the oil seal having a first surface capable of providing a fluid tight seal over an orifice in a testing surface when the oil seal is oriented correctly and having a second surface incapable of providing said fluid tight seal when the oil seal is oriented incorrectly, the system comprising:a testing surface having a sensor orifice and an exit orifice positioned to be sealed by the first surface when the oil seal is present and oriented correctly;an air supply means for regulating air supplied to the sensor orifice; andan air pressure sensor, whereby when the oil seal is present and correctly oriented with the first surface sealing the sensor orifice a back pressure of air is created at the sensor orifice and the air supply means, the back pressure being detectable by the air pressure sensor to confirm presence and correct orientation of the oil seal and when the oil seal is missing or incorrectly oriented with its second surface covering the sensor orifice no back pressure of air is created or detectable by the air pressure sensor, the air exiting to free space when the oil seal is missing and the air exiting through the exit orifice when the oil seal is incorrectly oriented.
