leak issues

hey guys, so for some reason my right rear cylinder wont hold air. checked every fitting,lines,valves and there are no leaks so i was thinking that maybe the actual cylinder could be leaking?? how would i check for that? could it possibly be something else?

Most likely a leaky seal in the cylinder. What kind are they and how old are they?

they are a year old and chassis tech cylinders.

oh i see. I would see if you can find a rebuild kit on their site.

alright, thanks bro
