Auto parts are all units that make up the overall processing of auto parts and products that serve the processing of auto parts. Sealing tests are required during the production of auto parts.

[0003] Publication No. (CN218271286U) discloses a sealing detection device for automobile parts. When in use, according to the inlet thread of the oil tank or water tank, an internal threaded joint or an external threaded joint is selected and screwed on the oil tank or water tank, and then the air valve corresponding to the threaded joint is opened, and the air pump starts to work to fill the oil tank or water tank with gas.
