·Enhanced Cylinder Leak Down Tester Kit: The 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 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.

·Convenient Dual Gauge Design: 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 cylinder compression tester, 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.

·Comprehensive Gauge Manifold Assembly: 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 compression tester and cylinder leakage test kit is compatible with most gasoline engines featuring spark plugs (within 20mm).

·Versatile Connectors and Extensions: 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.

·High-Quality Rubber Hoses: Long and short rubber hoses boast a 300 psi W.P and brass adapters at both ends (M14 x 1.25; quick plug), ideal for connecting the gauge hose assembly to the cylinder using selectable fittings.

·Customer Satisfaction and Warranty: Your satisfaction and recognition are our priorities. The product is eligible for unconditional return within one month, and we offer a 1-year warranty. Please feel free to contact us with any doubts or if you are unsatisfied with the product quality during use.
