Get the OEMTOOLS 37138 Compression Tester Gauge Set for an accurate reading on the health of your cylinders. This compression kit tester comes with a 14mm and 18mm 2-step compression test adapter and a compression gauge tester for servicing most cars and trucks. Inserting the adapters of our cylinder pressure tester into the spark plug ports is easy. Reaching the spark plug ports on your vehicle is no hassle thanks to the flexible design of the rubber hose extension in the cylinder compression tester kit. The O-rings on our adapters will give you a tight seal over the spark plug so that you receive an accurate airtight reading every time. Our compression gauge automotive tester reads from 0-300 PSI and can help diagnose sticking valves, cracked cylinder heads, worn cylinder walls, and more. Be sure to use the automotive compression tester on a known healthy cylinder before testing a suspected bad cylinder to get a good baseline reading. A healthy engine cylinder generally falls in the range of 100-150 PSI and this compression engine tester can help determine whether one or multiple cylinders are failing. Don’t be without a simple and efficient compression checker to conduct a compression test on your engine. Get the OEMTOOLS 37138 Compression Tester Gauge set today for ensuring the longevity of your vehicles.

Seems to be a really nice product, really happy with it. Doesn’t come with a lot of adapters for different sized spark plug holes

No issues with quality. Blow molded case is nice. Instructions are on a little placard, no papers to lose.I just followed the instructions in the factory service manual (test with warm engine, pull fuel pump fuse, etc.) -- pretty simple!

The first gauge I ordered read accurate however the pressure release valve would sometimes stick so you would get out of the car to a test of 0psi. Gauge would hold pressure when it did work.I ordered a replacement. The replacement had a bad hose causing it not to work. I tested this gauge also and it read accurately. Using the hose from the first kit I tested it on an engine. It worked however it does not hold pressure and starts dropping slowly right after the test. The first gauge held pressure and did not drop overnight.So do I dare try a third one? If it worked everything seems of good quality and the case is a major plus.

This the same Kit as sold in the Red Carrying Case. I have used both, and they both operate and perform the same. This is a very good tool for the cost. It's the best price I found online.
