The AxiLine Vacuum Tester (AVT) is designed to provide a source of vacuum for testing hydraulic circuits in transmission components, specifically to verify valve body cross leaks. The AVT eliminates the experience required for a wet air test (WAT). The power source is a standard shop air supply. The AVT can be used for any test requiring a vacuum source of 0 - 26 hg (inch mercury). Recommended air supply-100 PSI / 2.12 CFM.
