THINGS YOU SHOULD KNOW

Always apply green gas vertically and in 2-3 second bursts to avoid freezing your O-rings. If you freeze your O-rings, gas will leak. You can try to repair your O-rings by heating them up with a lighter and lubricating them with silicone oil. If they are beyond repair, you can purchase them at any local hardware store. Just make sure you lubricate them with silicone oil before applying them.
