Cylinder Leak-Down Tester Kit, Dual Gauge 0-100 PSI, 4 Adapters

Engine cylinder leak down tester kit helps pinpoint compression loss fast, so you can diagnose misfires, low power, and hard starts before you tear down the engine. Dual 0–100 PSI gauges show input vs cylinder pressure for quick comparison and leakage rate calculation. Built for cars and motorcycles, it includes multiple spark plug thread adapters plus mixed air fittings to match common shop air couplers. A heat-resistant hose and secure metal fittings support stable, repeatable readings.

• Delivers dual-gauge 0–100 PSI readings for clear input/cylinder pressure comparison and leakage percentage checks


• Includes M10, M12, M14, M18 adapters to fit common spark plug threads on many engines


• Connects with US/EU/JP/UK air fittings for tight sealing across different air supply couplers


• Reduces leaks with a heat-resistant silicone hose and knurled metal fittings for secure, corrosion-resistant connections


• Stores neatly in a compact carry case to keep parts organized for quick garage or mobile diagnostics

Use this leak-down and pressure check setup to confirm whether power loss comes from valves, rings, head gasket, or sealing issues—without guesswork. Setup is straightforward: remove the spark plug, connect the hose and adapter, set regulated air pressure, then read both gauges to assess cylinder sealing. Ideal for routine engine health checks, pre-purchase inspections, and troubleshooting after rebuilds. Keep it in your toolbox so you can verify engine condition whenever symptoms show up.
