I don't know why you guys are trying to get me to quit rving before I even get started. I'm confident that I can handle it. I guess I just wont ask for anymore suggestions on how to fix anything here. I thought that was what this forum was all about.
You were advised on how to deal with it but you didn't do it that way. The leak reappeared and now you want to blame someone else.
If you have a mechanical background, why don't you do this: Disassemble the connection and inspect it. I think what you'll find is a high-impact plastic nut pressuring a sealing washer. The washer seals against the surface of the valve's threaded supply extrusions.
Here's an old plumber's trick for stubborn/leaking fittings: Coat the sealing surfaces with pipe dope compound. Rector Seal is a good product. I wouldn't be afraid to use a tool on the fitting. You don't have to get King Kong about it. Pretend you are tightening a valve cover fastener. The correct tightening torque will compress the washer so the nut is held in position.
Good luck.
