Universal Compression Tester with 2.5-Inch Analog Gauge, 0-300 PSI

Brief Overview

This universal compression tester delivers reliable cylinder pressure diagnostics for gasoline engine diagnostics and troubleshooting. The kit includes everything needed for quick, accurate compression readings across a wide range of engine types. For shops requiring multi-fuel capability, consider pairing this with a diesel-specific compression testing kit to expand diagnostic coverage across your service menu.
