Propane leak

[Ole Sage]

My 30lb propane tank is leaking where the TT hose screws on.
It seems to be a tank valve problem. Screw it on my BBQ grill and it leaked there too. Is there a easy fix for this? Or change the whole valve.
There's about a 1/4 tank of propane

If the 'valve' is bad, it can be changed, but if it is only where it threads in, fix that. Close the valve. Have no flame around. Unscrew where hose attaches to tank. Put on teflon tape, get the YELLOW type(see below). Tighten hose to tank.... tighten a little more.... Get some soapy water. open tank valve and check for leaks.

I have changed out valves on 30lb tanks and it is something that I would NOT recommend that you do yourself if your not used to don't such things.

Could you be missing an O ring inside where hose connects??

I would not use any tape on the threads, this would only seal one part of the fitting. If you look at the fitting the threaded part slides on the fitting so there is another surface that would need sealed. Besides the threads is not what seals the connection on a propane tank. Its is a flared type connection and I believe there is a oring type of seal inside the valve or at the very tip of the hose that goes into the fitting. I cant remember off hand.

Change the valve, If the QCC (quick closing coupling) seal is damaged it is not repairable, we cannot even get the parts (I tried)
Good Luck
