Cylinder Leak Down Tester Petrol Engine Compression Leakage Detector Tool Kit

【Features】: it is used to detect many common faults of the engine, such as piston ring wear, cylinder head crack, valve wear and cylinder head seal burst. It checks the amount of leakage in the engine cylinders and helps determine the source of the leakage.

【General accessories】: It is very suitable for testing trucks and models with minimum clearance. Check the leakage of the four stroke engine.

【How the leak tester works】: once the leak tester is connected to one of the cylinders, compressed air (0-100 psi) enters the cylinder through an integrated pressure regulator. Diagnose by observing the amount of leakage shown on the cylinder leakage gauge and listening to the leakage at all points of the vehicle system. It is not applicable to shallow cylinders.

【Easy to operate】: remove the Schrader Valve and close the regulator before using workshop air. Install the hose on the cylinder, install the device on the air source, calibrate the leakage counter, and secure the device to the cylinder hose. Perform the diagnosis by observing the amount of leakage displayed on the cylinder leakage gauge and listening to the leakage at each point in the vehicle system.

【Versatile and Durable Connectors 】Constructed with aluminum and rubber, the straight/angled universal push-on connectors eliminate the need for threading into spark plug wells, making them compatible with almost all petrol engines. The M14 aluminum extension rod can be installed at the end of either the long or short hose (41-3/4" or 11-1/2"), extending the reach and enhancing operational convenience. Adapter sizes include M14*1.25, M18*1.5, M10*1, and M12*1.25, with high-quality, deep threads ensuring secure fitting and durability.
