- The working pressure range 30psi≤P≤110psi (2bar≤P≤8bar).
- A 1/4" NPT air compressor air pump quick coupler male plug for easy work.
- 300Psi/20Bar pressure tube with M12 and M14 thread to NPT, install the joint on the position of the spark plug.
- Durable rubber tube and brass fitting connectors, anti wear, high pressure resistance, anti corrosion and abrasion.

Why 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.

Worked well, easy shut off. Pressurized my engine cylinder to prevent valve from dropping.

Wishing the first 5 minutes of using it, it ripped! I heard a loud whistle and boom!! There’s a hole!

The hose on this is a bit questionable as it is a hard tube versus a rubber floppy style. This may make it an easier way to get it to thread in the spark plug hole. It doesn't come with a pressure gauge but I believe I can add one in-line. I don't think I would have titled it as a leakdown tool with no Guage, but should be fine to put air into a cylinder and hold the valves up to replace springs.

The hose says it’s rated for 4500psi but couldn’t handle 100… blew up and valves dropped into cylinder… do not rely on this for changing valve springs or seals…
