Fast Detection: Equipped with a 10-200 psi high-precision digital gauge and a built-in hold valve, this engine cylinder compression tester kit can capture and display peak compression pressure for quick sealing evaluation

Wide Compatibility: The engine compression test kit includes four commonly used size adapters (M10, M12, M14, M18) and straight/angled extended metal tubes, fitting most gasoline and diesel spark plug ports

Compact & Portable: A custom case keeps all parts neatly secured. The sturdy, lightweight box is easy to carry and store, keeping the compression tester kit organized and ready to use

Sturdy & Durable: A heat-resistant silicone hose provides strong sealing, while knurled metal fittings ensure tight, corrosion-resistant connections. Our compressor tester kit ensures long-term reliability and stable measurements

Easy Setup: The compression test kit performs a simple compression test (detach the spark plug, connect the digital gauge, crank the engine, and read the result). Clear instructions help you quickly check the basic cylinder condition
