Compression Tester Set Petrol Engine Deep Reach

A cylinder compression tester set for petrol engines, used to check compression where spark plug ports are deep seated and awkward to reach. Built for direct and indirect injection engines, it gives a clear way to assess engine condition during diagnosis, servicing and fault finding.

Used for garage work, workshop checks and home vehicle maintenance, this type of cylinder pressure tester helps when investigating poor starting, uneven running, loss of power or suspected internal engine wear. It is useful for mechanics and experienced DIY users carrying out engine diagnostics, whether testing a single cylinder or comparing readings across the engine. The deep reach arrangement makes it more suitable for engines where standard testers struggle to access recessed plug holes.

The set includes thread chasers in M10, M12, M14 and M18 sizes, covering common petrol engine plug thread applications from the supplied range. A dual scale gauge makes readings easier to follow during testing, while the built-in pressure relief valve allows repeat checks without dismantling the setup between tests. That can save time when comparing cylinders or confirming results after additional checks. For regular servicing and fault diagnosis, having the common thread options together helps keep testing straightforward.
