OMT 8pc Petrol Engine Cylinder Pressure Test Kit with 300 PSI Dual Gauge

Performed as expected. Results less than desireable, but that's not the tool's fault. I'll attribute the poor compression to a long string of POs on a 45 year old bike.

Good quality low cost unit. Does just exactly what it is designed to do. Easy to read dial. Good value for the money.

EDIT: though I was well past the return date because I wasn’t at the point of my tune up to test my compression, as other reviewers said, the customer service was fantastic, and they sent me a replacement gauge. So, you can purchase knowing that if there’s an issue, you will be taken care of by this seller. Thank you! Original review: Pressure not accurate. Did test twice on separate days (because I was so disappointed in my results initially). Yes, my engine was warmed up, yes I had the throttle fully open, and yes the choke was open (not choked). My results were CONSISTENT, but not accurate. Gauge measured 90, 65, 85, 90. Then I did the tsp of oil test down the spark plug wells, and I got 95, 90, 90, 95. Yes, I know no. 2 is a little off, and it would be a concern at this level. I took my bike to my mechanic to weld a hoop on, as I don't have a welder, gave him my numbers and asked him to check for me. I went in today, and he said my compression was fine: 150, 125, 150, 150 and that while no. 2 is a little concerning, its within the range that I'll be O.K. at least for now. Of course, I'm past the return time, so I'm stuck with an inaccurate compression tester.

Exelente producto gracias

This product has the right idea, ill give it that. But I used this on a stihl bg55 blower i was having issues with, decided to check the compression with this tool, it showed less than 20psi. I figured the piston rings were bad so I tore the motor apart. Come to find out the tester just sucks. I used it on another engine im working on, which has good compression just by feel, but I wanted to test the tool to see if it was a fluke. That second tool with the spark plug in, has good compression, hook up the tester, and the piston seems to spin a lot more freely and once again only shows about 20psi. So something is leaking on the tester somewhere, and I saw some other buyers claimed the same thing. Don't waste your money on this tester. Im going to purchase the mityvac compression tester here soon as it's build quality seems a lot better. Saw a comparison video between the two and the mityvac has Schrader valve in the line, to keep the pressure in the gauge helping to give a more accurate reading.

This one works great,good readings

Great product and a must have for anybody who does their own engine repair work. Fast and easy to use save me from making a bad purchase on two separate occasions.

It works just like it should

works

Macht, was es soll. Liegt messtechnisch gleichauf mit einem professionellen Werkstatt-Tester. Gutes Set mit vielen Adapter. Auf jeden Fall für die Hobby-Werkstatt zu empfehlen.

Bought this kit for checking chain saw compression. All necessary parts included.

Conforme à la description

Great for hobby mechanics..
