Dual-Gauge Engine Cylinder Leak-Down Tester

Compare cylinder leakage on a compatible four-stroke engine with a dual-gauge leak-down tester and regulated workshop air.

✅ See the leakage reading during the test - The gauge arrangement provides the described reference while the cylinder is pressurised.

✅ Investigate where air escapes - The test supports checking possible leakage paths as part of the engine diagnosis.

✅ Set the incoming air for the procedure - An integrated regulator provides the control stage for a suitable compressed-air supply.

Compare cylinders under the correct test conditions

A leak-down test checks how a prepared cylinder holds supplied air rather than measuring cranking compression. The readings and observed escape paths give a technician information to consider alongside other engine checks.

Use the engine's procedure for piston position, crankshaft restraint and safe pressure. Confirm adapter and clearance compatibility before purchase; the kit is not a universal fit and the result does not by itself identify every cause.
