    You can get loc tight 515 ( is what I like) at united or re Michel ., other professionals on here may suggest a different # . But remember don't over due it, and it does as its name says.

    Depends on the fitting. >1/4" NPT/S fittings I use nothing but teflon tape. I use a tap and die to clean up any threads that look questionable. <1/4" NPT/S, I've had pretty good luck lately with that Nylog stuff that everyone here loves to rave about. Vacuum grease is nice, but I don't use it on threads. I use it to help install and seal small o-rings, and also to help big o-rings stay stuck in place. It's also handy for making sure copper gaskets stick to flare fittings when you're putting a cap on. One tube will last a very long time.

    No problem. Thanks for returning to check on your threads and participating in active conversation, instead of starting a thread and going AWOL like most new members do.

    While working for a manufacturer leaks were a majority warranty expense. At one time, all mechanics working for the company had to attend a class put on by Loctite. We had very specific instructions on what we could and could not use.

    We were specifically instructed that Teflon tape was unacceptable. In the early days of this new awareness we were told to use Loctite 565. Later the company started using a more aggressive sealant Loctite 554 refrigerant sealant for fittings 3/4" and up. Eventually, the company went to SAE fittings and o-rings. Through the education and use of appropriate sealants the warranty claims for leaks were cut dramatically.
