Works!
Used it to swap out the springs in a VW engine. Per the instructions on the box, 30-50 psi working pressure. Set the hose pressure to 30 psi and carefully opened the valve. Worked like a charm! Kept the valve closed while I swapped the springs. Glad I have this tool. Not sure how many times I will be able to use it but I'll post an update if needed.

Thumbs up
This product works great for allowing air to enter the cylinder to keep your valves from dropping in. Would definitely recommend to anyone else.

Hose blew up on first use!
It says 4500 psi working pressure. Well my ears and my 120psi compressor would beg to differ. Amazon bears some safety responsibility for allowing this dangerous item to be sold on their site. Do not think you will get lucky. Don't buy it.

Worked for me
This thing worked great. The only thing keeping it from a 5 star product is the fact I had to use an adapter for my particular application. Would've been nice if that was included. Luckily the adapters from a pressure gauge work well. All in all, it did the job.

Spark Plug Air Compressor Attachment
The media could not be loaded. Pros: Ball Valve (on/off) lever, two size spark plug threads.Cons: Had different male attachment for my air compressor. It would be nice if it wasnt shipped with it on because it is hard unless you have a vice to remove and change it out.Overall: It is useful and I plan on utilizing it to run a small motor from compressed air. Thank you

Works great
I always used to use the hose from my cylinder leak down kit but now I won't have to worry about wearing out my leak down kit.
