I have 6 Bosch air cylinders. I was going to make a lift for quads and bikes but lost intrest. they are used, they all seem to work and are rated at 10 BAR dont know what that is in PSI but its pretty strong dont know how often they where used or what they are for. but they dont seem to leak I hooked A couple of them up to a small air compressor at about 50 pounds and didnt hear any leaks. IF anybody is interested i'll check the rest. If anybody wants one just let me know 10.00 each+S/H or 50.00 +S/H for all six
