Cylinder Leak Down Tester Kit
Convenient dual gauge design allows the compression gauge tool to test the pressure and leak rate of the cylinder under test at the same time. Ranging from 0-100 psi / 0-7 bar and 0-100%(Accuracy: ±0.5%), easy to read 3-inch gauges would spend less time on readings.

Assist To Detect Following Engine Faults.
Worn piston rings, worn valves, cracks in cylinder walls and blown head gaskets.
- ensure that the air valve regulator is in the "off" position before connecting to the air supply.
- will require an air pressure of 45 to 100 psi.
- Warring! ensure the air supply is clean and does not exceed the pressure quoted. too high an air pressure and/or unclean air will shorten the life of the tester due to excessive wear and may be dangerous, causing damage and/or personal injury.
- drain the compressor air tank daily. water in the air line will damage the tester.
- clean compressor air inlet filter weekly.
- line pressure should be increased to compensate for unusually long air hose (over 8 meters). the minimum bore for hose and fitting is 1/4".
- keep hose away from heat, oil and sharp edges. Check hos es for wear and make certain that all connections are secure.
Safety Tips
- Air pressure should be controlled within the range: 45-100 psi.
- Turn the knob counterclockwise first before the cylinder compression tester connects to the air compressor.
- Please read the instructions carefully before operation and best to be accompanied or guided by professionals as you work.
- Tidy up all used tools and equipment and never leave them in, on or near the engine.
- The item will be packed well to prevent damage in transit, if something ever fails, please let us know for a satisfactory solution within the effective period.

Works well, but the 10mm adapter for motorcycles with deep well spark plug locations the diameter is to large. Simple fix, quick turn down on the fitting to reduce diameter of the adapter and all was good. Calibration was spot on as well, tested with multiple gauges for reference 👍

It worked just as it was advertised and the case it came in was nice because it keeps all parts together.WEP.

A seperate quick release gauge on the manifold would have been more beneficial for a quick compression test or some quick release adaptor for another gauge. but, still, a very versatile compression tester.

Première utilisation et le pointeur cadran est resté en plein milieu du dial. Je ne recommande pas
