Review on ๐Ÿ”ง Mityvac 5530 Professional Compression Tester Kit - Black: Get Accurate Engine Readings by Brian Elliott

Revainrating 3 out of 5

You forgot something.

Part quality is good but if you have a countersunk spark plug hole you will need to thread the adapter into the spark plug hole by applying torque to the hose. WTF? This can be corrected by splitting a short piece of appropriately sized tubing and attaching it to the hose and then slipping a pair of O-rings over the split halves. You're still applying torque to the compression fittings, but you can at least avoid twisting the threads. Did the designers fall asleep before reaching the finish line?

Pros
  • Slim design
Cons
  • Boring pack
