2 Gauge Leakdown Tester

Racers prefer the dual gauge design of our Leakdown Tester to check for problems with piston rings, valves, head gaskets, etc. The left hand gauge shows incoming air pressure, while the right hand gauge (once plugged into the cylinder being checked) shows how much air the cylinder is holding. The difference between the two gauges is your leakdown. A universal 14mm spark plug adapter, rubber gauge protectors, high-quality regulator and complete instructions are all standard with our precision Leakdown Tester
