How to Refill a Scuba Cylinder

Video Transcript

"So, this is to show you how to fill a scuba cylinder for use underwater. This should only actually be done by someone that knows what they're doing, an expert, and one of the first things that you want to make sure that you recognize is how what pressure that you're going to fill the cylinder to. So, in this case, this is an aluminum cylinder, and the working pressure for this cylinder is three thousand PSI. Now, what we want to do is check and make sure that there's actually an O ring in the tank. And we go ahead and slide our whip on to the cylinder. The next thing to actually do is close the bleed valve of the tank. And at this point, you could go ahead and turn on or open up both valves. And actually let air into the cylinder. Now, with our compressor system, this fills eight tanks at a time. And we would then go ahead and turn on our compressor and when it hits three thousand PSI it's going to stop."
