What Thread sealant would you use radiator trans cooler

I just received a new radiator and I need to reinstall the fittings for the trans cooler lines but do not know which thread sealant is best? I have locktite blue removable thread sealer, will that work?

Wow... OK. I wasn't sure, I thought it needed a sealant because the original fitting had some sort of sealer on the threads.

Just to be clear, My cooler lines push into a fitting that is screwed into the radiator and the lines are held in place by a c-clip. So the threaded area I was talking about was the fitting that screws into the radiator. Thanks for all the replies!

Hmmm, hang on a sec.

Just to be clear, you should never use any kind of sealant on a tube nut to inverted-flare fitting connection.

However, the use of sealant on the *pipe thread* end of the fitting that screws directly into the radiator cooler is OK.
Note that pipe thread is actually slightly tapered, so that it gets tighter as you turn it in.

Sealant simply helps to lubricate it and fill any voids. It also assists in preventing galvanic corrosion between dissimilar metals ... which facilitates future removal.



In other words, sealant applied to the male threads of the fitting on the LH side, but no sealant for the tube nut that screws into it.

Tube thread, on the other hand, is not tapered. In fact, it is usually the same thread as a UNF (fine thread) bolt.
As you can see in the cutaway view, the tube nut forces the flared tubing down onto an inverted seat forming a mechanical seal.
