Cylinder Leak Down Tester Kit with Extension Rod for Gasoline Engines – Automotive Compression Leakage Tester for Cars, Trucks, Motorcycles, Pressure Check, Leakage Rate Test

Product Features Dual dial synchronous reading After connecting the air compressor, the pressure gauge (0-100 PSI/0-7 bar) and leakage rate gauge (0-100%) of this cylinder compression tester work simultaneously. Without the need for conversion, one can easily identify which cylinder is leaking beyond the standard and directly locate the fault. Straight/curved push in connector The leakdown tester kit is equipped with two types of connectors that are compatible with different spark plug hole positions (upright, side, inclined, etc.), and can be installed without threads and sealed when pushed in, covering almost all gasoline engines. M14 aluminum extension rod+long and short hoses The leak down test kit is equipped with a long hose (47.2 inches) and an extension rod that can penetrate deep into the spark plug hole; Short hose (11.5 inches) is used in confined spaces, doubling the testing range and no longer giving up detection due to difficult location. AR2000 pressure regulating valve+push-pull locking knob When using the cylinder leak down tester kit, simply pull out the knob to adjust the intake pressure of the air compressor (recommended 45-100 PSI), push it into the lock to prevent pressure fluctuations caused by accidental touches during testing, and ensure stable and reliable leakage rate readings. Non threaded quick connector The engine leak down tester adopts a non threaded quick plug connector, which can be locked and released with one push and one pull. It does not stop during cylinder replacement testing, and the efficiency of the entire process is improved by 50%. aluminum alloy body The compression leak down tester adopts an aluminum alloy valve body, which is corrosion-resistant, anti-collision, and has a long service life. Even if used daily, it is not easily damaged. More accurate diagnosis The traditional replacement method is time-consuming and laborious. This small engine compression tester directly displays the percentage of leakage, and with the help of auscultation method (exhaust port, intake port, crankcase), it can accurately distinguish between valve leakage, piston ring wear, and cylinder gasket damage. Lock the fault point within 15 minutes to avoid mistakenly replacing parts. More time-saving operation The engine compression tester adopts a non threaded joint and quick plug design, eliminating the step of twisting the spark plug adapter, which is three times faster than traditional threaded testers, especially suitable for scenarios where repair shops have to pick up multiple vehicles and tight schedules. Wide adaptability range The cylinder compression tester kit is equipped with straight/curved double joints and M14 extension rods, covering the vast majority of gasoline engines such as cars, motorcycles, trucks, etc. (with sufficient depth of spark plug holes), without the need to purchase additional accessories for different vehicle models, it can be done in one set. anti-misoperation design The automotive compression tester is equipped with a push-pull locking knob, which can be locked after adjusting the pressure. Even if the regulating valve is touched during the testing process, the pressure will not change, and the leakage rate reading is consistent before and after, with good reproducibility. Attention: This small engine compression tester kit is not suitable for shallow cylinders

• Engine Cylinder Leak Detector: The cylinder leak down tester can be connected to an air compressor (user-provided) and helps identify common engine issues such as piston ring wear, valve wear, cylinder wall cracks, and head gasket failure
• Dual gauge design: The fuel pressure tester kit features a clear dial that directly displays the pressure value and leakage rate of the tested cylinder. The measurement ranges are 0 - 100 psi (0 - 7 bar) and 0 - 100% (accuracy: ±0.5%), suitable for gasoline engines with spark plug hole diameters ≤20mm
• Accessory Details: The leak down tester includes 1 dual-head manifold, 1 rubber hose, and 2 metal adapters, along with 2 universal push-in connectors, 2 threaded adapters, 1 M14 extension rod, and 1 extension hose
• Scale: The leak detection scale tool is equipped with an 18-inch hose, AR2000 pressure regulator, American-style air nozzle, and manifold body. The knob is pulled out for pressure adjustment and pushed in to lock. The non-threaded quick-connect fitting, along with extension rods and short/long hoses, expands the operational range
• Application Area: Compression test kit has universal straight and bent quick connectors, simply push in for use without screwing into the spark plug hole, compatible with almost all gasoline engines. The M14 aluminum extension rod can be connected to the end of a long hose (47.2 inches) or a short hose (11.5 inches)
