Compression gauges with O-rings are precision tools used to test the compression levels of engines in various vehicles, including cars, motorcycles, and boats. These gauges are designed to provide accurate readings of the pressure generated within the cylinders of an engine, helping to identify potential problems such as worn piston rings or leaking valves.
