Cylinder Leak Down Tester
Use:
The cylinder air leakage measuring instrument is suitable for detecting whether the air tightness of automobile engine cylinder is within the allowed air leakage range; it can further determine the location and cause of air leakage from the analysis of fault phenomenon, so as to take measures to eliminate the fault.
Principle:
The detection principle is when the engine is at rest, the piston is in the stroke of the upper dead center position, to the cylinder to inject a certain amount of compressed air. The time it takes for the air pressure to drop to the specified value reflects the size of the leak. The shorter the time, the larger the air leak.3 Conversely, the smaller the air leak. If constant pressure air is continuously supplied, the main areas causing air leaks can be determined so that engine maintenance can be targeted.
Main Technical Parameters:
Pressure measurement range: 0-1 MPa
Inlet air pressure range: 0-l.6 MPa
Working air pressure: 0.6-0.8 MPa
Easy To Use
1. Before using shop air, remove the Schrader valve and close the air regulator valve counterclockwise. Connect a separate rubber hose to the pressure gauge assembly, observe the cylinder being tested and decide on that basis if either of the M10 or M12 adapters need to be installed.
2. 2. There are 2 methods of testing. Either one is your preference.
1. Direct type test
The meter tester can be connected directly to the 10" rubber hose for spark plug testing.
2. Screw-in test
Based on the first method, install one of 2 aluminum adapters (M10/M12).

Female brass fitting that's supposed to have 4 steel balls in it to grab the male fitting, are not there idk what foreign non existing quality control is done but they skipped a pretty basic part. Guess that's what I get for ordering cheap Amazon alibaba crap.

I would not recommend this product I could even use it on time! ,the cylinder leakage gauge got stock when I was adjusting the regulator Don't Waste your money buy a name brand like OTC

tool comes with no instructions so i used it the same as i used my mac tester (which has a bad hose) the leak down gauge never returned to original position and is now useless...

Bought this to do a leak down test on a 4 cylinder engine. Would have like it to test around 100PSI of leakage and it would not let me go over 45PSI. Even with the compressor set to well over 110PSI.Useless for its job. You get what you pay for with these kits. Buy a good $200 one and save the time.

This is not a dual purpose leak down/compression tester as the ad leads you to believe. Unless you have an extremely low compression engine since the gauge only goes to 100.

I am pretty sure I got a defective unit. It did not work properly at all. I’ve used many leak down testers before, and I followed the directions with this one, so I am confident I was using it correctly. Despite this, it did not work right. I returned it and got my money back. I wish I had a working unit to test it properly and give a better review, but it is what it is. Very well packaged and looked like a quality product, but I think it was partially clogged, thus giving wildly inaccurate readings.
