CYLINDER LEAK DOWN + COMPRESSION TESTER
On the basis of a common set(1PC double gauge maniflod, 1PC rubber hose and 2PCS metal adapters included), this 3-in-1 cylinder gauge diagnostic tool kit adds 2PCS universal push-on connectors, 2PCS threaded adapters, 1PC M14 extension rod, and 1PC extension hose.
Convenient dual gauge design allows the leak down tester gauge assembly to directly show you the pressure value and leak rate of the tested cylinders. Ranging from 0-100 psi / 0-7 bar and 0-100%(Accuracy: ±0.5%) ,Compression leak tester hooks up to air compressor(provide yourself) can help to detect common engine faults such as worn piston rings, worn valves, cracks in cylinder walls and blown head gaskets.
Leak down tester gauge also equipped with 18" rubber hose, AR2000 pressure regulating valve, American type air plug and aluminum body. Valve knob made of alloy and plastic, used for pressure adjustment of the input air from the air compressor. Pull out for use, and push back to lock. This compression tester & cylinder leakage gauge test tool kit fits for any gasoline engines with spark plugs(within 20mm).
Constructed with aluminum and rubber, straight / angled type universal push-on connectors don't need to be threaded into spark plug wells and applicable to almost all petrol engines, and M14 aluminum extension rod can be installed on long / short hose(41-3/4"; 11-1/2") end to increase distance and facilitate operation. Adapter sizes: M14*1.25, M18*1.5, M10*1, M12*1.25.
ADAPTERS
- M14*1.25
- M18*1.5
- M10*1
- M12*1.25
DIFFERENT CONNECTING BAR
Coming with different connecting bar,can be used in different ways.It is easy for operating.
- 1 x straight bar for easy reached place
- 1 x bent bar for hard to reached place.
- 1 x entension bar for long distance place
PRESSURE REGULATING VALVE
- Pull out to use
- Push back to lock
- Clockwise twist to increase air supply
- Anticlockwise twist to reduce air supply
- Turn regulator knob fully anticlockwise before connecting to compressed air
Assist To Detect Following Enging Faults
Worn piston rings, worn valves, cracks in cylinder walls and blown head gaskets.
Location Of Detect Foints
- Oil dipstick tube — for leakage from damaged or worn rings and/or cylinder wall.
- Radiator filler — for cylinder wall cracks or head gasket leakage.
- Adiacent cylinder — for head gasket leakage.
- Carburettor air inlet — for inlet valve leakage.
- Fuel injection throttle body — for inlet valve leakage.
- Tail pipe — for exhaust valve leakage.

I had to make my own adapter to fit the cylinder head that I was working on. The tester worked just fine. The leak percentage gauge might not be that accurate, as it went below 0% at 100 psi when testing the tool itself. I calibrated it by making an air-tight cap for the adapter, and finding what psi yielded 0% leakage, which ended up being around 96 psi, so not far off. When using the tester, I only take it up to 96 psi and I know that the leak percentage reading should be fairly accurate.

Tried to calibrate tool before using as described in instructions but tool wouldn't calibrate at all like it says. Therefore tool was junk and couldn't be used to do a leakdown test.

I got the product as one day delivery and it seemed good (at least at first look). Without wasting your time, let's see the pros and cons:Cons:Everything is made out of cheap material, the seals started leaking as soon as I connected a compressor to it. It wasn't working. I was getting 5% leak in a cylinder which had 0 compression at all. Wasted money, wasted time and wasted efforts. A person should be paid even to buy this one.Pros:I didn't see any.

The original o-ring did not seal other than that really good stuff

Went to use for the first time and now the hose is stuck inside cylinder head. Unable to remove given the depth and given the end connector is round (has no hex head)... This is the main hose with the ARO quick-connect fitting one one side and a crimped 14 mm threaded end on the other, which turned out to be defective.

It’s what I expected for the price. It’s a good product and seems solidly built comes with all the accessories that I need and works. Can’t ask for anything more.

Hey, for this price it's pretty good!Not top quality but also a fraction of the cost of top quality.Used it on a snowblower that I suspected had a leak but it didn't.So as far as that goes it works very well.Case plastic is a bit on the cheap side but at least it has a case.I'd say it's well worth the cost.If I run into problems with it down the road I'll update this comment but so far so good!

Building a Mk1 VW with a 1.8t 20V swap and I needed to check the health of the engine, I was a little nervous about the cost of this kit but it worked great. It helped located a few minor issues. Its one of those rarely used tools that is nice to have and at this price point I cant complain!

Zeros at around 28 psi and it works great for the price you can't beat it and didn't have to pay a shop to do this who knows if the guy doing it knows what he's doingI was able to rule out internal issues with this tool, all the cylinders were within a few % of each other and that's what's important consistency that combined with perfect compression numbers tell me it's fine internally even at 200k
