Features: The Cylinder Leakage Tester precisely diagnoses engine faults like valves issue, and cylinder cracks through double gauge pressure/leakage readings. Features a metal plastic construction with integrated pressure regulator (45-100PSI) and double gauges for simultaneous leakage percentage and cylinder pressure monitoring during engine diagnostics. Ideal for professional mechanic, automotive enthusiasts, and repair shops requiring accurate engine health assessments on car, trucks, and motorcycles with 4 strokes engines. Optimized for workshop diagnostics, and identify leaks via detection and visual leakage data during cylinder compression tests. Simplifying engine troubleshooting with hole adaptability, enabling rapid leak source identification across valves systems, and head gaskets.
