New Cylinder Leak Down Tester (TU-21) Engine Cylinder Leak Tester Leakage Detector Engine Compression Tester Gauges SetNice set with a nice protective case for doing compression and leak-down testing. Comes with various size attachments and hoses to handle the job at hand. It has a quick disconnect at the hose/plug tp ease relocation without possible damage to the gauge set.This is one of those tools that the average personal mechanic might use once or twice a year but when one needs it, it's now. So great to add it to the kit. Had old compression guage with a single fittings. This is far and away a better setup.I don't need a $400 setup... This is a good price performer

The kit comes in a nice case. It has all the adapter I need for my dirt bikes. The kit is easy to use and well made. Good price for a tool I will use a couple times a year, but nice to have in my box.
