What is an Otc Leak Down Tester?

An Otc Leak Down Tester is a diagnostic tool used to check the sealing integrity of an engine’s valves, rings, and head gasket.

Key Features to Consider

  1. Pressure Gauge: Look for a tester with a high-quality pressure gauge that provides accurate readings in both PSI (pounds per square inch) and BAR (barometric pressure). The gauge should also have a large display for easy reading.
