Product Description Leak Down Tester Compression Leak Down Tester,Cylinder Leak Down TesterCylinder Leak Down Tester, Leak Down Tester Leakdown Tester Engine Pressure TesterThe comprehensive cylinder leak down tester kit introduces six new components, expanding your diagnostic capabilities for a superior repair experience. Building upon a foundational set (1 double gauge manifold, 1 rubber hose, and 2 metal adapters included), this 3-in-1 cylinder gauge diagnostic tool kit (Engine Pressure Tester) incorporates 2 universal push-on connectors, 2 threaded adapters, 1 M14 extension rod, and 1 extension hose—essential additions for both DIY enthusiasts and professional mechanics. The dual gauge design facilitates simultaneous testing of pressure and leak rate within the cylinder under examination. Covering a range of 0-100 psi / 0-7 bar and 0-100% (Accuracy: ±0.5%), the easy-to-read 3-inch gauges streamline the reading process, saving valuable time. The compression tester & cylinder leakage gauge test tool kit, connected to an air compressor (to be provided separately), aids in identifying common engine issues such as worn piston rings, valve wear, cylinder wall cracks, and blown head gaskets. The gauge manifold assembly is equipped with an 18" rubber hose, AR2000 pressure-regulating valve, American-type air plug, and an aluminum manifold body. The alloy and plastic valve knob allows for precise pressure adjustment of the air input from the compressor—pull out for use and push back to lock. This leak down tester leakdown tester engine pressure tester kit is compatible with most gasoline engines featuring spark plugs (within 20mm). Constructed with aluminum and rubber, the straight/angled universal push-on connectors eliminate the need for threading into spark plug wells, accommodating almost all petrol engines. The M14 aluminum extension rod, usable on long/short hoses (41-3/4"; 11-1/2"), increases reach and facilitates operation. Adapter sizes include M141.25, M181.5, M101, M121.25, ensuring compatibility. Deep threads provide superior grip, anti-slip properties, and durability.
