Description

Compression tester from BGS Technic

Gauge to measure the amount of compression in your cylinder.

A lack of compression can cause loss of power or the engine not starting, and this tool can save a lot of wondering and inconvenience, as you can find out if the engine lacks compression and can therefore indicate whether your cylinder is leaking or worn, a simmer ring is not seated correctly or similar, without taking anything apart and visually inspecting the engine.

Adapters are included to screw into the 14mm and 18mm spark plug threads. The clock can display up to 20 bar or 300 psi.
