1. Enhanced Diagnostic Capabilities '3in1 cylinder gauge diagnostic tool kit an advanced set of tools, including universal pushon connectors, threaded adapters, extension rods, and hoses, providing comprehensive testing capabilities for a wide range of engine diagnostics. 2. Dual Gauge Design for Simultaneous Testing The compression gauge tool features a convenient dual gauge design, allowing for simultaneous testing of cylinder pressure and leak rate. The easytoread 3inch gauges display readings ranging from 0100 psi / 07 bar and maintain 0 accuracy (Accuracy: ±0.5%), ensuring efficient and accurate interpretation of results. 3. Effective Leak Detection Equipped with a leakdown gauge tool, this kit aids in detecting common engine faults such as worn piston rings, valves, cracks in cylinder walls, and blown head gaskets. When connected to an air compressor (not included), the robust manifold assembly, including an 18' rubber hose, AR2000 pressure regulating valve, American type air plug, and aluminum manifold body, ensures precise pressure adjustment for reliable diagnostics. The valve knob, made of alloy and plastic, facilitates pressure adjustment. 4. Versatile and Connectors Constructed with aluminum and rubber, the straight/angled universal pushon connectors are compatible with almost all petrol engines. The M14 aluminum extension rod can be installed at the end of either the long or short hose (413/4' or 111/2'), extending the reach and enhancing operational convenience. Adapter sizes include M141.25, M181.5, M101, and M121.25, with highquality, deep threads ensuring secure fitting and durability.
