• 8-in-1 Tool Kit:The KOOPOOL Cylinder Compression Tester Kit includes: 1 compression gauge, 1 straight rubber cone end adapter, 1 curved rubber cone end adapter, 4 adapters with metric male fittings and O-rings (M10, M12, M14, M18), 1 16.3-inch extension hose, and 1 fabric pouch
• Durable Constructio:The KOOPOOL Cylinder Compression Tester is a professional-grade tool designed for quick and accurate measurement of gasoline engine cylinder pressure. Constructed from high-quality materials, it features rust and corrosion resistance for long-term durability. The pressure gauge dial is protected by a rubber cover for enhanced durability. The 7x3 inch fabric pouch with securing straps ensures components are protected from impacts during transport
• Ease of Use:Featuring a dual-scale gauge with quick-connect fittings, it provides precise data readings. The pressure testing range is 300 psi and 20 bar, with a one-click pressure release to reduce the risk of fuel injection when disconnecting. Adapters in sizes 10 mm, 12 mm, 14 mm, and 18 mm allow easy connection to corresponding cylinder heads. The straight and curved connectors with rubber cone ends ensure a secure fit on almost all cylinder head sizes. The extension hose enables measurement in tight spaces
• Wide Application:This engine cylinder compression tester tool can measure cylinder pressure in motorcycles, cars, trucks, ATVs, lawnmowers, or any other gasoline or gas engine vehicles. However, note that its compression testing range is limited to 0-300 PSI, making it unsuitable for diesel engine cylinders
• Usage Steps:Firstly, ensure the vehicle is parked on a flat surface and the engine is cool. Secondly, remove the fuel pump and fuel injection fuses, disconnect the main coil wire and spark plug wires, and remove the spark plugs. Then, manually thread the compression gauge into a spark plug hole. Finally, turn on the ignition, depress the throttle, and crank the engine four times to obtain accurate data
