11PC Compression Tester, Compression Tester Tool Kit, For testing cylinder compression, Includes 5 adapters: M10, M12, M14, M16, M18, For compression testing on

Application: Cylinder pressure gauge with various sizes of rotating and plug-in adapters, widely used in most types of gasoline and gas engine cylinders and deep spark plugs, often found in motorcycles, lawnmowers, cars, trucks, and off-road vehicles. Note: This compression gauge is NOT suitable for diesel engines. Multifunctional: The cylinder pressure gauge is used to detect a multitude of common engine faults, such as: stuck valves, carbon deposits, cracked cylinder head or faulty main gasket, faulty or worn piston ring assembly, burnt or damaged piston, etc. Cylinder Stethoscope: This mechanical stethoscope is equipped with a sensitive acoustic chamber that amplifies sounds, allowing you to easily detect problems in your engine. The thin diaphragm and extension probe locate the source of the noise, while the ear tips isolate you from outside noise so you can fully concentrate on detecting the problem. This engine stethoscope includes a medium probe and a long extension tube. The medium probe helps locate noises over a wider area. Dual-scale pressure gauge: Dual-scale pressure gauge, measuring range of 0 to 20 bar (0-300 psi), acrylic glass cover and protective rubber cover to prevent scratches, offers excellent shock absorption. Thanks to the integrated one-way valve with pressure hold function, our engine compression gauge provides accurate measurements. Engine compression tester: This cylinder test kit includes 1 spring-loaded tape measure, 5 brass adapters (M10, M12, M14, M16, M18), 1 metal extension connector, 2 aluminum metal rods (straight and curved), an extension tube with M12*1.25 thread, and a rubber extension tube (16 inches), as well as an engine cylinder stethoscope.
