Mityvac MV5530 Professional Compression Test Kit, Includes Everything Required for Performing Dry and Wet Compression Testing on Gasoline or Petrol Engines

This is by far the best compression tester I have ever used, two thumbs 👍 up mityvac, great product .

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.

Habe auch schon 3 Kompressionstester umd das ist der erste der mich nicht belügt.

This is my 4th different compression tester that I buy... Finally something that actually works!!! Silverline air leaks everywhere. Sealey cheap one, inaccurate reading. The hose does expands due to pressure... Sealey deluxe 100 pounds and the same problem... This one the way it is build I can compare to a snap-on one. You have several varieties of sizes and it even comes with a service kit. For the price, quality and accuracy I doubt you are going to find a better one. The picture with the reading is on a bike with a cold engine. Just wanted to test the compression quickly.

Found the kit to be very well made, from the blow moulded case down to the spark plug adapters, and it was a nice thing to find consumable spares such as o rings in the kit.The rubber hoses are good quality and suitable for what they need to do. flexible but not too flexible and will take a adapter out of a deep cylinder head without collapsing.The airline fittings felt nice and had a positive engagement with no leaks.The guage had a nice smooth action, and most importantly was consistent. I dont care if its inaccurate by a small percentage, but i want it to be consistent, and it was.From memory i think it comes with spare schrader valves for the guage to which is a bonus.All round a well made and at the price, a very good value tool. I have used several different brands prior, both name brands from leading auto shops like from bursons to cheap eBay chinese offerings, and i wont ever bother to use anything else in future if i need to replace it. Im now snooping around for vacuum tester as i know i will get quality. Thanks
