Check the listing for details. Professional Cylinder Leakage Tester Compression Leakage Tester. Color: Black, Condition: New. Listed at 44.55 USD. Item description from the sellerProfessional Cylinder Leakage Tester Compression Leakage Tester【Features】: it is used to detect many common faults of the engine, such as piston ring wear, cylinder head crack, valve wear and cylinder head seal burst. It checks the amount of leakage in the engine cylinders and helps determine the source of the leakage.【General accessories】: It is very suitable for testing trucks and models with minimum clearance. Check the leakage of the four stroke engine.【How the leak tester works】: once the leak tester is connected to one of the cylinders, compressed air (45-100 psi) enters the cylinder through an integrated pressure regulator. Diagnose by observing the amount of leakage shown on the cylinder leakage gauge and listening to the leakage at all points of the vehicle system. It is not applicable to shallow cylinders.【Easy to operate】: remove the Schrader Valve and close the regulator before using workshop air. Install the hose on the cylinder, install the device on the air source, calibrate the leakage counter, and secure the device to the cylinder hose. Perform the diagnosis by observing the amount of leakage displayed on the cylinder leakage gauge and listening to the leakage at each point in the vehicle system.【Package】: 48cm recoil hose, 10mm and 12mm spark plug adapters, fixed connector M14 x 26mm, fixed connector M16 x 26mm, pressure+cylinder leakage gauge, air regulator, instructions and case.Product DescriptionCylinder Leak Down Tester Compression Test KitThis is a high quality TU-21 cylinder leak detector, including double gauge systemDesigned to detect a variety of engine faults, including worn piston rings, worn valves, cracked cylinder walls, and blown head gasketsEasily check the amount of leakage and locate leaks area in an engine cylinder to help determine the sourcerSuitable for use on any petrol engine with 12 or 14mm spark plugs, and ideal for testing trucks & late model cars where clearance is minimalPressure gauge with dual scale reads from 0 to 100 PSI and 0 to 7 Bar, shows pressure in PSI and Bar and percentage of cylinder leakagePACKING LIST1x Dual Gauges Assembly with 19" Hose and American Style Air Plug1x 10" Rubber Nylon Resin Hose with 14mm Brass Coated Aluminum Adapter1x 10mm Aluminum Adapter with O-ring1x 12mm Aluminum Adapter with O-ring1x Detailed Instruction1x Customized Blow Molding Case, 12.6"L x 8.66"W x 3.74"HADAPTERSConnect to the corresponding sizes spark plugs on most gasoline engine14mm Brass Coated Aluminum Adapter14mm Brass Coated Aluminum Adapter and 12mm Aluminum Adapter14mm Brass Coated Aluminum Adapter and 10mm Aluminum AdapteDUAL GAUGES ASSEMBLY WITH HOSEAvailable with either single gauge shows % of cylinder leakage, or twin gauge manifold show cylinder leakage and cylinder pressureAmerican Style Air PlugAir Regulator ValveManifold BodyCylinder Pressure Gauge, 0-100psi/0-7barCylinder Leakage Gauge, Marked HIGH MODERATE LOW SET19" Rubber Nylon Resin HoseBrass Quick CouplerPRESSURE REGULATING VALVEPull out to usePush back to lockClockwise twist to increase air supplyAnticlockwise twist to reduce air supplyTurn regulator knob fully anticlockwise before connecting to compressed airAssist To Detect Following Enging FaultsWorn piston rings, worn valves, cracks in cylinder walls and blown head gaskets.Location Of Detect FointsOil dipstick tube — for leakage from damaged or worn rings and/or cylinder wall.Radiator filler — for cylinder wall cracks or head gasket leakage.Adiacent cylinder — for head gasket leakage.Carburettor air inlet — for inlet valve leakage.Fuel injection throttle body — for inlet valve leakage.Tail pipe — for exhaust valve leakage.NOTEPlease wear gloves and goggles when use.This cylinder leakage test kit should be used by professional or under the guidance of a professional.Always refer to equipment manufacturer's operation instruction, compare to the manufacturer's recommended readings.Select neutral (or "park" if automatic transmission) and keep hands clear of the engine as engine rotation may occur when using this tool. The ignition MUST BE turned off.This cylinder leak tester is not suitable for shallow cylinder. Please check your cylinder first before bidding.Turn regulator knob fully anticlockwise before connecting to compressed air.Require an air pressure of 45 to 100psi. Ensure the air supply is clean and does not exceed the pressure quoted.Unscrew the adapter after the cylinder is cooled to prevent the hose from softening and not driving the adapter to rotate together.
