  • High Quality, Accurate
Very nice piece of equipment. A must for small engine (as well as automotive) diagnostic work. This unit has Schrader valves on all the hoses, where they screw into the spark plug hole. This gives a much more accurate reading. Also comes with spare parts such as o-rings and Schrader inserts.

  • Mityvac MV5530 Engine Compression Test Kit
Nice testing kit. Has long and short thread adapters. Used it to test a Kawasaki KX85. Showed about about 150 PSI, which is good news. All components appear well made.

  • A must have for the DIY enthusiast
This thing has saved me hundreds of dollars on everything from chainsaws to cars and every engine in between.

  • I Would Have Preferred
I would have preferred that the hoses were extensions instead of having fixed attached plug hole adapters. This would have made it possible to adjust the length making the unit more flexible. That said, good set. I only checked one cylinder so actual accuracy is unknown but better than my old (15 years +) KD Tools which read 125lbs on all cylinders. Cold Block Test of 350 #1 Cylinder with 111,000+ miles: 3 test results were Consistent - 155lbs 155lbs 155lbs and held pressure. ... show more

  • Compression guage
Unit has a good selection of accessories, is well made and will last a long time. Price was more than expected but should last, shipping was good and packaged well.

  • Absolutely Great!
This compression gauge set is first class. It has all the adapters that you will ever need. As a bonus they included spare o rings too. The gauge is big enough for you to see at a distance and the quick disconnect makes changing the adapters a breeze. I love it.

  • Good quality
Worked as expected. Had the adaptors i needed for the job i used it for. This item will come in handy for future projects.

  • Great product and value
Used it on checking the integrity of the cylinders on a 2017 Kia Forte and it performed flawlessly. Easy to use and didn't break the bank. Liked the big numbers on the gauge and I really liked that it came with extra seals and valve core stems. I'm really starting to like MityVac products. I own this kit and the Brake Bleeder (Metal Housing) and they both performed exceptionally well. ... show more
