There are many videos on how to refill a 1 pound LPS cylinder. However, not all of them show you how to ensure the process is correct. 100-200 psi is the green zone for Propane. The safety valves are usually set to around 250 psi. Overfilling is dangerous. Not advice. This is video is strictly for educational purposes.
***When using the 1lb to 20lb adapter make sure the BBQ (20lb) end is connected first and the cylinder end is connected last or it WILL release propane***
