This compression tester works with most car models with gasoline engines. It comes with adapters and tubes in different sizes for different car models. The set is used to quickly and accurately check the compression on the engine cylinder. The two-tone gauge with 0 - 300 psi / 0 - 20 bar scale can be quickly used on your motorcycle or car so you can take accurate measurements on valves, piston rings, cylinder bores and cylinder head gaskets. It is rust resistant and fully copper nickel plated. In addition, the included extension rod makes it possible to safely and easily perform pressure tests on vehicles with difficult to reach access points. The set comes in a blow-molded case for easy storage and transport.
