●The multi-piece leak down tester kit adds 6 new partners to give you more options and a better repair experience. On the basis of a regular set(Set includes 1PC double gauge maniflod, 1PC rubber hose and 2PCS metal adapters), this 3-in-1 cylinder gauge diagnostic tool kit adds 2PCS universal push-on connectors, 2PCS threaded adapters, 1PC M14 extension rod, and 1PC long reaching extension hose. It is a must have for any DIYer or professional mechanics tool collection. ●Convenient dual gauge design allows the leak down tester gauge assembly to directly show you the pressure value and leak rate of the tested cylinders. Ranging from 0-100 psi / 0-7 bar and 0-100%(Accuracy: ±0.5%), easy to read 3" gauges spend less time to give accurate results. Compression leak tester hooks up to air compressor(provide yourself) can help to detect common engine faults such as worn piston rings, worn valves, cracks in cylinder walls and blown head gaskets. ●Leak down tester gauge also equipped with 18" rubber hose, AR2000 pressure regulating valve, American type air plug and aluminum manifold body. Valve knob made of alloy and plastic, used for pressure adjustment of the inputed air from the air compressor. Pull out for use, and push back to lock. This compression tester & cylinder leakage gauge test tool kit fits for any gasoline engines with spark plugs(within 20mm). ●Constructed with aluminum and rubber, straight / angled type universal push-on connectors dont need to be threaded into spark plug wells and applicable to almost all petrol engines, and M14 aluminum extension rod can be installed on long / short hose(41-3/4"; 11-1/2") end to increase distance and facilitate operation. Adapter sizes: M14*1.25, M18*1.5, M10*1, M12*1.25. High quality and deep threads allow the fittings to bite better, antislip and durable. ●Long & short rubber hoses feature 300 psi W.P and metal adapters at both ends(M14 x 1.25; quick plug)- Ideal for connecting the gauge assembly to the cylinder with the metal fittings. Your satisfaction and recognition are always what we pursue. The product can be returned unconditionally in one month and we also supply 1 year warranty.

2. Air Supply and Pressure Regulating Valve(AR2000)
American type air plug is used for the air compressor connection.
Black valve locks as you push back and unlocks in reverse.
3. 18" Flexible Hose
Working pressure: 300 psi. Hose endures torsion and pressure extremes to ensure safe use.
Quick disconnect with 4 ball bearings for better grip.
It can be connected to short / long rubber hose(11-1/2" and 41-3/4"), and universal push-on connectors.
Cylinder Compression Gauge Manifold
Test range: 0-100 psi / 0-7 bar(pressure gauge); 0-100%(leakage gauge).
Gauge scale displays cylinder pressure value and leakproofness.
Detects cylinder system faults and finds the leakage sources.
Dual Gauge Manifold
Consists of pressure regulating valve, twin gauges, valve and hose.
One-piece convenient tool for efficient work.
Extension Hoses & Extension Rod
Extension Hoses: 41-3/4" and 11-1/2" in length. Ended with the M14 brass fittings and quick plugs.
M14 Extension Rod: Made of high-quality aluminum alloy and adopt anodized technology. With M14 Male and Female connectors at ends. Smooth and beautiful. Easy to install.
Hoses can work with extension rod for longer distance.
Universal Push-on Connectors
No need to thread into spark plug wells.
2 types(straight type and angled type) for optional choice.
Metal Adapters
Threaded Adapters
Sizes: M10*1; M12*1.25; M14*1.25; M18*1.5.
Constructed with aluminum and brass. Long durability and good sealing with O ring.
Dual Gauge Manifold
Extension Hoses & Extension Rod
Universal Push-on Connectors
Metal Adapters
Multiple Connection Modes
1. Gauge manifold directly connects to push-on connectors for quick test.
2. Gauge manifold directly connects to short / long rubber hose for another choice. With metal adapters if required.
3. Longest connection. Connect both ends of short / long hose to gauge manifold and M14 extension rod respectively, and the latter can also be screwed to a metal adapter for size adjustment.
Safety Tips
1. Air pressure should be controlled within the range: 45-100 psi.
2. Turn the knob counterclockwise first before the cylinder compression tester connects to the air compressor.
3. Please read the instructions carefully before operation and best to be accompanied or guided by professionals as you work.
4. Tidy up all used tools and equipment and never leave them in, on or near the engine.
5. The item will be packed well to prevent damage in transit, if something ever fails, please let us know for a satisfactory solution within the effective period.
Range of Application
Ideal for use on a large number of gasoline engines with spark plugs (within 20mm).
