Leakdown Testers

Engine diagnostics demand precision—a leak down test reveals exactly where combustion pressure is escaping, whether through worn rings, valve seats, or gasket failures. The Total Seal Dual Gauge system gives you real-time, dual-channel readings so you...

A leak down test is one of the most critical diagnostics you can perform on an engine—it reveals precisely where compression is being lost before catastrophic failure occurs. The Proform 66839 dual gauge system gives you professional-grade accuracy to...

Accurate leak-down testing is essential for diagnosing ring blow-by, valve seat wear, and gasket integrity—issues that directly impact compression and power output. The Longacre Digital Leak Down Tester delivers repeatable, quantifiable results so you...

A leak down test is essential diagnostic work that tells you exactly where compression is escaping in your engine—information you can't get from a standard compression check. The Longacre 52-73010 gives you dual gauges to measure both the air pressure...

Engine diagnostics demand precision, and a leak down test reveals compression loss that a standard compression gauge cannot detect. This dual gauge setup allows you to pinpoint ring blow-by, valve seat leakage, and gasket failures—critical information...
