This professional COMPRESSION TESTER is a widely used engine diagnostic tool for UK auto garages, mobile mechanics and DIY car enthusiasts to test cylinder compression of petrol vehicles. The pressure gauge features dual printed scales: 0 to 21 kg/cm² and 0 to 300 PSI, which meets different measuring reading habits and ensures precise test results. It is fitted with a 50cm long flexible pressure hose, together with two pressure tubes including straight tube and bent tube. The angled tube helps access narrow hidden positions on the engine block without excessive disassembly, achieving comprehensive engine pressure detection. Four interchangeable threaded adapters are fully included: M10×1.0, M12×1.25, M14×1.25 and M18×1.5. These connectors fit most spark plug holes of cars and motorcycles, greatly expanding the application range of this pressure test kit.
