Universal Petrol Engine Compression Tester Kit (0-300 PSI)

Stop Guessing. Start Diagnosing. Is your engine losing power? Struggling to start? Don't start throwing expensive parts at the problem until you know the truth. The Mankind Cylinder Compression Tester gives you an immediate, accurate reading of your engine's internal health, pinpointing issues with valves, piston rings, cylinder bores, or head gaskets.

Designed for total versatility, this kit includes four thread adapters (M10, M12, M14, M18), making it compatible with everything from chainsaws and motorcycles to cars and trucks.

Why It Belongs in Your Toolbox:

• Precision Dual-Scale Gauge: The large 75mm diameter gauge provides clear, accurate readings in both 0-300 PSI and 0-20 Bar.
• Universal Compatibility: Whether you are working on a bike (M10) or a car (M12, M14, M18), this kit has the right adapter.
• Quick-Check Rubber Cones: In a rush? The kit includes 2x rubber cone adapters (straight and angled) that allow you to simply push the gauge into the spark plug hole for a rapid reading without needing to thread it in.
• Built to Last: The drain valve features full copper-nickel plating to prevent oxidation and corrosion. The gauge itself is encased in a rubber protector to survive the inevitable drops and knocks of garage life.
• Extended Reach: Includes a 430mm flexible hose, allowing you to reach deep-set spark plug wells on modern engines.
