A compression tester adapter is provided. The compression adaptor includes a generally cylindrical plug fitting, including a pilot segment, an external thread, a cylinder segment, a gasket located between the external thread and the cylinder segment and a plug end; and a connector fitting including an attachment interface; and a hose attached to the plug fitting. A method of adapting a compression tester spark plug hose for use with a spark plug socket is provided. The method includes; engaging a threaded spark plug socket in an internal combustion engine cylinder head; attaching a compression tester spark plug hose; and transmitting a compressed gas to the compression tester spark plug hose wherein the spark plug socket thread is configured with a nominal diameter of 12 millimeters; and creating a substantially airtight seal against a periphery of a tapered seat near a inner extreme of the spark plug socket.
