Question LP Tank connector leaks sometimes

I have a green Acme hand tightened connector that connects my 7 gallon hitch tank to the black hose going to the dual tank regulator.

For some reason if you hit the hose just right an audible leak sound occurs around the green acme connector. No amount of hand tightening will stop the leak, and Im pretty strong. But if I just push the hose to one side a little it will stop.

Im wondering if there is a seal/o-ring that is cracked or worn on my tank female fitting or the Acme Connector?

The soap bubbles develop at the front and back of the green grip, so the leak is somewhere in the Acme connection.

Need some advice on what to look for.

there is an O-ring in there ... I am not sure if they are easily replaceable but you can see them on the female part of the connection.

What I have done is to put some faucet lube in the fitting and on the o-ring. That seemed to work to stop a minor leak.

I had several flies fall out of an Acme fitting once when I undid it to refill the tank one time. It appears that they like the smell of the propane perfume like spiders do.

Also check both sides of the coupling the make sure the surfaces are clean and free from burs.

Joe I went throught a problem with a bad valve seat on a 9 year old tank. Here is a Link to the write up I did on troubleshooting and the end result. The rubber seat in the valve is not repairable and the valve has to be replaced as a unit. It was interesting that it would leak with one 'pigtail' but not the other. Just a matter of compression and fit.

The way the link opens, you might have to move up the page slightly.

Hope this helps
