Cylinder Leak Tester, TU-21 Engine Cylinder Leak Tester, Dual Gauge Gasoline Engine Leak Tester Compatible with 10, 12, and 14 mm Spark Plugs, Red

Universal Fit: Suitable for any 4-stroke gasoline engine with 10, 12, or 14 mm spark plugs. The engine leak tester checks the number of leaks in an engine cylinder and helps locate the source. Ideal for testing newer model trucks and cars where clearance is limited. Easy to Read: The dual-gauge leak tester is convenient for testing cylinder pressure and leak rate simultaneously. Range: 0-100 psi / 0-7 bar and 0-100% (accuracy: ±0.5%). Each gauge is 3 inches in diameter. 【Operating Principle】Once the leak tester is connected to one of the cylinders, compressed air (45-100 psi) is introduced into that particular cylinder via the built-in pressure regulator. The diagnosis is performed by observing the amount of leakage indicated on the cylinder leak gauge and listening for leaks at various points in the car's system.
Quality Material: The leak tester kit has a robust construction. The adapters are made of high-quality aluminum and brass-coated aluminum. The hoses are made of premium nylon rubber resin, which is pressure-resistant and does not break easily.
