Compression Tester Kit 65mm Petrol Engine M10 M12 M14 M18

A compression tester kit for checking cylinder pressure on petrol engines during fault finding, servicing and general vehicle maintenance. The 65mm gauge gives a clear reading and the kit includes M10, M12, M14 and M18 adaptors to cover a useful range of common applications.

Used when diagnosing hard starting, poor running, misfires or suspected loss of compression, this kit helps give a clearer picture of engine condition before further repair work begins. It suits garage work, workshop use and home mechanics carrying out engine checks on cars, motorcycles and other petrol-powered equipment where the listed thread sizes are suitable.

The gauge has a dual scale reading from 0 to 300psi and 0 to 2000 kPa, making it straightforward to read in either format. A 400mm flexible extension helps when access is awkward around the engine bay, while the straight and angled push-on connectors give more choice depending on the plug position and available working room. The included adaptor sizes make the kit more practical for repeated servicing and diagnostic work, helping avoid the need to source extra fittings for common petrol engine testing jobs.
