Is there anything in a regulator to keep you from dialing to high of a pressure? My regs don't like when I go over 20psi. I don't remember having this problem when I first started kegging. I dial up to about 40psi to seal my corny and I get a very small burst of gas. I took off my quick connect and pressed the button with my finger and same thing. I dial it to 15 and I get a nice steady flow. I swapped my reg to a newer one last time this happened and things seemed to work fine. I went to seal a couple of tanks the other day and the problem happened again. I knew I was almost out of gas so I thought that was the problem. I tried a full tank and I still have the problem. Am I missing something here?
