Customer Reviews for VEVOR Compression Tester Adapter Kit, 9 Pcs Automotive Engine Cylinder Leak Down Compression Test, Accurate Dual Scale Pressure Gauge 0-300 psi, with Long Reach Hoses and Case for Engine Cylinders

wow I can't say one good thing about this. didn't hold compression reading after tighten up value stem wouldnt read the compression. Had to goto parts store to rent one from them just to do a simple LS check. want to return

Hoses are very stiff ,even when warm , quick connections not the best , hard to connect fittings, had to use a lubricant to make any of the connections work , my biggest issue is that the hoses are so stiff that it makes it very difficult to use, not a recommended product, needs upgrading in materials

When I first got this, it wouldn’t hold pressure using the threaded adapters provided for the size spark plug hole on my dirt bike. I added some Teflon tape to the threads and this fixed the issue and helped it seal properly. Overall better than many of the cheap ones, but mine also did arrive with one of the 3 balls in the air hose fitting missing - looks like it fell out somewhere before I got it. Still works ok with two, and for the price, it’s decent. Would buy this again in preference to many of the really cheap ones.

Had to be replaced by manufacturer when the release valve would not work under high pressure. A+ for customer support.

The kit is leaking from every clamped connections on every hose. The kit is leaking from every fitting and quick pneumatic coupler. If you try to put teflon on the threads to make them air thight, you will explode the connectors when screwing them back together. DO NOT BUY! ABSOLUTE WASTE OF MONEY! VEVOR IS NOT COOPERATIVE IN SENDING ME A NEW KIT!
