Diagnoses engine compression problems with this easy-to-read digital gauge. 300 PSI digital gauge with a rubber boot, and a quick disconnect fitting. The 12 in. hose has a stepped adapter for 14 and 18mm plugs, plus a 10 and 12mm adapter. Gauge holds the reading for 90 seconds, or until the RESET button is pressed. Automatically shuts off after 3 min. includes a 9V alkaline battery.
The compression tester works well for my car, but I found the instructions a bit confusing at first. It took me a while to figure out how to use the quick disconnect feature. Once I got it set up, though, it gave me the accurate readings I needed. Not bad overall!

Accurate and easy to use!
I recently bought the Performance Tool W89747 to check the compression on my old Jeep engine. The 300 PSI gauge is really precise, and the quick disconnect feature made it a breeze to switch between cylinders. Definitely made diagnosing my engine performance easier!

Stopped working after a few uses
I was really hopeful about the Performance Tool W89747, but it stopped giving accurate readings after just a few uses. I took good care of it, so I’m not sure what went wrong. It’s frustrating because it seemed like a good product at first.
