Feature:

Convenient dual gauge design allows the compression gauge tool to test the pressure and leak rate of the cylinder under test at the same time. 

The leakdown gauge tool, which hooks up to an air compressor(prepared by yourself), can help to detect common engine faults such as worn piston rings, worn valves, cracks in cylinder walls and blown head gaskets.

Gauge manifold assembly is also equipped with an 18" rubber hose, an AR2000 pressure regulating valve, an American type air plug and an aluminium manifold body.

The leak-down tester gauge is also equipped with a pressure-regulating valve, used for pressure adjustment of the input air from the air compressor. Pull out for use, and push back to lock.

Constructed with carbon steel and rubber, straight/angled type universal push-on connectors don't need to be threaded into spark plug wells and are applicable to almost all petrol engines, and the M14 aluminium extension rod can be installed on long/short hose(41-3/4"; 11-1/2") end to increase distance and facilitate operation. 

Specification:

Ranging from 0-100 psi / 0-7 bar and 0-100%(Accuracy: ±0.5%), easy-to-read 3-inch gauges would spend less time on readings.

Adapter sizes: M14*1.25, M18*1.5, M10*1, M12*1.25. 

This leak down compression tester & cylinder leakage test kit fits for most gasoline engines with spark plugs(within 20mm).
