Compression Tester
A compression tester is a diagnostic tool used to measure the compression pressure within each cylinder of an engine. It is a handheld device that typically consists of a pressure gauge, a rubberized hose, and a threaded spark plug adapter. The compression tester is connected to the spark plug hole of each cylinder, and the engine is cranked or turned over using the starter or a pull cord. As the engine turns, the compression tester measures the pressure buildup within the cylinder during the compression stroke. This measurement provides valuable information about the engine's overall health, including the condition of the piston rings, valves, and cylinder head gasket. The compression tester is an essential tool for diagnosing engine performance issues and identifying potential problems.

When selecting the correct compression tester, there are a few factors to consider. Firstly, you need to ensure that the compression tester is compatible with your engine's spark plug size and thread pitch. Compression testers typically come with different spark plug adapters to fit various spark plug sizes and types. It is important to choose a compression tester with the appropriate spark plug adapter that will securely and snugly fit into your engine's spark plug holes. Additionally, consider the range and accuracy of the pressure gauge on the compression tester. Look for a compression tester with a gauge that can measure the compression pressure within the expected range for your engine's specifications.
