Engine Air Valve Holder Pressure Pipe with Ball Valve M12 M14 Thread to 1/4 NPT Cylinder Leakage Testing Assistant Tool for Ford for Mustang for LS1 for LS2 for LS3 4.8 5.3 6.0 Trucks

Application: Used for the gasonline engine cylinder with M14 or M12 spark plug, have to move out spark plug before install this tool. Note the working pressure range 30psi≤P≤110psi(2bar≤P≤8bar).

• Fit for: Engine Air Valve Holder is widely use in almost for LS engines. Fit for gasoline powered vehicles such as cars, trucks, boats, motorcycles, all terrain vehicles, and UTVs. Not applicable to diesel engines.
• Function: When replacing valve springs or valve stem seals, compressed air helps to keep the valves closed, pressurizing the cylinder to help quickly detect the cause of low cylinder pressure (exhaust pipe leakage or throttle valve leakage). Damaged components can also be diagnosed by the sound and location of engine leaks during compression.
• High quality materials: Made of high quality rubber pipes and brass joints, with strong wear resistance, high pressure resistance, and corrosion resistance. Can prevent the air valve from falling into the combustion chamber.
• Package include: 1x engine air valve bracket, pressure pipe with ball valve. Please carefully check before purchasing. The 4500PSI mark on the pipe is not the air working pressure. Please note that the working pressure is 30psi ≤ P ≤ 110psi.
• Easy installation: When using a 300Psi/20Bar pressure pipe with M12 and M14 threads, install the connector at the spark plug position. There is a 1/4 "NPT air compressor air pump quick coupling male plug for easy operation. Note the working pressure range 30psi≤P≤110psi(2bar≤P≤8bar), the spark plug must be removed prior to installation of this tool.
