Cylinder Leak Tester, Compression Tester, Engine Leak Test Tool with Two Pressure Gauges

Material: made of high quality alloy, sturdy, good toughness and high hardness. Fault Detection: Identifies worn piston rings, worn valves, cracks in cylinder walls and blown head gaskets. How it works: Measures cylinder leaks and locates the source of the leak. The measuring range is 0-100 psi or 0-7 bar. During the test, the pressure in the cylinders of the normally operating engine is compared with the measured pressure to determine the leak. Application: suitable for petrol engines with 10mm or 12mm spark plugs and ideal for testing trucks and cars, especially in confined spaces. Note: This product is a gas cylinder leak tester and should be used with air pump. It cannot be used as a pressure gauge for gas cylinders.
