Compression Tester | 0-300 PSI Gauge | M10-M18 Automotive Adapters

This gasoline engine compression tester kit helps you find problems inside your engine by checking cylinder pressure. It's a basic tool for diagnosing engine issues like worn piston rings, burnt valves, or a bad head gasket before they cause bigger trouble for your car, truck, or motorcycle. Features and Benefits - Clear 2.5-inch gauge - It reads from 0-300 PSI (0-21 bar), so you can easily see if a cylinder has low compression. - Four thread adapters - You get M10, M12, M14, and M18 sizes. These fit the spark plug ports on most gasoline engines. - Flexible 13-inch hose - The rubber hose makes it simple to reach cylinders in tight engine spaces. - Quick-release valve - A push-button valve on the side lets you release pressure and re-test without unscrewing the adapter. Applications - Routine engine checks - Do a compression test on your car or truck to track engine wear over time. - Used vehicle inspections - Quickly check an engine's condition before you buy a used vehicle. - Small engine repair - This tool helps you find compression loss in motorcycles, lawnmowers, and other small engines.
