Multi-Function Cylinder Leak Down Tester Automotive Kit,Gasoline Engine Compression Tester
The 10PCS leak down tester kit includes different type connectors to give you more options and a better repair experience. On the basis of a regular set(Set includes 1PC double gauge , 1PC rubber hose and 2PCS metal adapters), this 3-in-1 cylinder gauge diagnostic tool kit adds 2PCS universal push-on connectors, 2PCS threaded adapters, 1PC M14 extension rod, and 1PC long reaching extension hose. It is a must have for any DIYer or professional mechanic's tool collection.
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%), easy to read 3" gauges spend less time to give accurate results. 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. High quality and deep threads allow the fittings to bite better, antislip and durable.
Long & short rubber hoses feature 300 psi W.P and metal adapters at both ends(M14 x 1.25; quick plug)- Ideal for connecting the gauge assembly to the cylinder with the metal fittings. Your satisfaction and recognition are always what we pursue.

Worked great for leak down testing as intended. Be aware, this and other leak down testers are sensitive to the length of supply hose. If you have a 50' supply line to the tester, you really need to turn it up to get to ~100psi (instructions do say you need to compensate for long supply hose, but you may be surprised how much). Would recommend.

It was exactly as shown, and made sturdy.

First time using this, I barely hand tightened the hose into the spark plug tube. Besides ALL the fittings being wrong (if you could hook it up backwards it'd be perfect, but all the males needed to be females and vice versa) I go to take the hose out and it just keeps spinning, endlessly spinning. The metal crimped connector at the end of the hose, where it goes into the threaded fitting, loosened. NOW I HAVE THIS HOSE STUCK 6 INCHES DOWN A SPARK PLUG TUBE, WITH NO WAY TO UNTHREAD IT. I'LL HAVE TO SPEND HUNDREDS TO GET SOMEONE TO FIX THIS, OR TAKE THE HEAD OFF AND UNSCREW IT FROM THE OTHER SIDE. BAD QUALITY "TOOL"

Bought this to test the compression loss on my boat motor. Works great and told me exactly which piston needed new rings.

It works good and arrived when they said it would.

We gave this to our neighbors son and he says for minor testing it's perfect.
