This creation is about a faucet water pressure and air pressure testing machine, especially a test machine for testing the faucet components waiting for the airtightness and watertightness of the test piece.

In the process of assembly and testing, the valve components such as the faucet need to pass the gas detection and water detection to determine whether the performance and function of the product meet the standard requirements.
