Engine Leak Down Tester Digital 14mm

The Engine Leak Down Tester Digital 14mm by Longacre is an essential tool for mechanics and engine builders who need to assess the integrity of internal combustion engines. This precision diagnostic instrument helps identify where and how much pressure is lost during the combustion cycle, providing insights that a standard compression test cannot offer.

Using regulated compressed air introduced into the combustion chamber, this digital leak down tester measures the percentage of pressure loss across various leak paths. The 14mm adapter thread is compatible with most spark plug ports, making it suitable for a wide range of four-stroke gasoline and diesel engines, including automotive, marine, and small-engine applications.

With its digital readout, users can easily monitor real-time percentage values, distinguishing between acceptable wear and critical losses. The tester's compact design, measuring 9.3 x 5.5 x 12.2 inches and weighing 4.15 pounds, allows for easy storage and transport, making it a valuable addition to any mechanic's diagnostic kit.
