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 facilitat.
