Engine Air Valve Holder Pressure Pipe Valve for LS Engine Valve Spring Compressor Air Holder Stem Seal Removal to 1/4 NPT Cylinder Leakage Test Assistant Set Auto Replacement Parts

ApplicationUsed for the gasonline engine cylinder with M14 or M12 spark plug, have to move out spark plug before install this tool. For most of for LS engines, suit for gasoline engine, car, truck, boat, motorcycle, ATV, UTV etc. Not for Diesel EngineSpecification:Color: BlackMaterial: Rubber, Metal, BrassSize: 48cm / 18.90"Thread Size: M12x1.25, M14x1.25Include 1 x Engine Air Valve Holder Pressure PipeWhy Need this Engine Air Valve Holder Pressure Pipe?Insufficient cylinder pressure can cause the car to shake.Quickly detect the cause of low cylinder pressure, whether it is valve leakage or piston ring leakage.Pressurizes the cylinder to raise the valve to convenient replace valve oil seal without dismantling cylinder head.Compressed air to help to keep the valve closed when replacing valve springs or valve stem seals, pressurizing the cylinder.How to Check of damaged parts by listening to the leak position:Exhaust pipe leak/noisy means exhaust valve ablation.Throttle leak/noisy means intake valve ablation.Oil cap leak/noisy means problem of piston ring.Feature:300Psi/20Bar pressure tube with M12 and M14 thread to NPT, install the joint on the position of the spark plug.A 1/4" NPT air compressor air pump quick coupler male plug for easy work.The working pressure range 30psi≤P≤110psi (2bar≤P≤8bar).Durable rubber tube and brass fitting connectors, anti wear, high pressure resistance, anti corrosion and abrasion.Air pressure avoid the valve to falling into the combustion chamber.The mark 4500PSI on tube is not air woring pressure.

• Fitting: [Application] Used for the gasonline engine cylinder with M14 or M12 spark plug, have to move out spark plug before install this tool. Apply for most of for LS engines, suit for gasoline engine, car, truck, boat, motorcycle, ATV, UTV etc. (Not for Diesel Engine)
• Benefit: [Function] Compressed air to help to keep the valve closed when replacing valve springs or valve stem seals, pressurizing the cylinder. Help to quick detect the reason of cylinder pressure low(Exhaust pipe leak or Throttle leak).
• Features: [Feature] 300Psi/20Bar pressure tube with M12 and M14 thread to NPT, install the joint on the position of the spark plug. There have a 1/4" NPT air compressor air pump quick coupler male plug for easy work. Note the working pressure range 30psi≤P≤110psi(2bar≤P≤8bar).
• Useful: [Reliable Material] Adopt with durable rubber tube and brass fitting connectors, anti wear, high pressure resistance, anti corrosion and abrasion. Air pressure avoid the valve to falling into the combustion chamber.
• Detail: [Package] Include 1x Engine Air Valve Holder Pressure Pipe with Ball Valve. Please check carefully before purchase. The mark 4500PSI on tube is not air woring pressure, please aware the working pressure is 30psi≤P≤110psi.
