Dual Gauge Design: Convenient dual gauge design allows the compression gauge tool to test the pressure and leak rate of the cylinder at the same time. Ranging from 0-100 psi / 0-7 bar and 0-100%(Accuracy: ±0.5%)
Application: The leak down tester kit is used to detect common engine faults such as worn piston rings, worn valves, cracks in cylinder walls and blown head gaskets
Different Adapter Size: Includes different adapter size(M14*1.25, M18*1.5, M10*1, M12*1.25). High quality and deep threads allow the fittings to bite better, antislip and durable
Universal Push-On Connectors: The straight/angled type push-on connectors don't need to be threaded into spark plug wells, for almost all petrol engines. M14 aluminum extension rod can be installed on hose end to increase distance and facilitate operation
Pressure Regulating Valve: The engine compression tester is equipped with pressure regulating valve,used for pressure adjustment of the input air from the air compressor. Pull out for use, and push back to lock
