The Compression Tester Adapter is used to connect the compression tester to the engine's cylinder head or glow plug port. This connection ensures that the compression pressure is accurately measured without any loss or interference, allowing the tester to gauge the pressure generated during the compression stroke. It is made of steel material.Attributes:• Provided with a hexagonal shape for a better gripping surface for tightening and loosening the adapter• Provided with good wear resistance and strength to resist deformation under stressApplications:The Compression Tester Adapter serves as a link between the compression tester and the engine, ensuring a secure and leak-free connection during the compression testing process.
