never seize on brake couplers?

[AHofner]

My simple brake job has taken a turn for the worse. None of the brake line barrel connectors want to come loose. I am replacing the hard and soft line from the rear junction block to the right rear caliper. BTW, if you ever have to do this, Mopar sells the hard line (pre-bent) and the soft line as an assembly for $20! I thought I was getting the deal of a lifetime and the parts guy couldn't believe that was the actual price either.

I digress; so I would like to avoid all of this in the future by keeping the barrel couplers from rusting together. What can I use to accomplish this? My first thought was teflon tape on the threads, but dad said that was a No-No; so that's out. He thought maybe never seize, but that doesn't sound like a good idea for a coupler that needs to stay tight. Perhaps blue loctite? Just a dab, I know, but I think a dab would go a long way in keeping rust out and the brake lines connected. Better yet, is there a compound designed for this sort of connection? Another thought is to leave to couplers dry, but wrap them in that thick black electrical wrap so as to seal them up from the elements, but still allow for a tight secure connection.

Thoughts, comments suggestions are encouraged.

I have used never-seize on them before with good results... the main thing is you need to slide the nut back and get the line too, because they typically seize to the line, not the fitting.

my dad just replaced some on a repo S10 he got ahold of, the lines were seized to the connector so we had to replace a few lines but got it back together with no issues, My 92' is getting the works over when it comes back from the shop, radiator is going to the boiler for a cleaning, checking and replacing all brake lines, fitting that need it, i got plenty of PB blaster on hand and a heating torch lol...
We used wheel bearing grease on the new fittings on the S10 how well it will work we don't know but we also use high temp red grease on the farm and that stuff will stick to anything and stay forever, so i may use that on my truck and see what happens.

and a heating torch lol...

I hope the "lol" meant you wouldn't put the torch to the brake lines. That may be worse than getting your fuel lines loose with one.

lordy no. . PB blaster only for that, to all those reading "do not use a heat source on brake lines" will result in a much larger blow torch affect. .

I think I would just grease them, but if you don't want to put grease or never-seize on the fittings, how about paint? It seems that a good coat of primer followed by a couple of coats of flat black paint would do the trick. You would be painting after the system is sealed, so there's no chance of paint getting on the inside.

anything to keep the connections from corroding, i honestly think more folks need to be checking their brake lines esp. if they live in areas that get winter, alot of muddy area's any place a line can get hidden and junk lay in behind a part or bracket will eventually cause issues. I think paint would work or you know i had a brain fart, what about silicone like you use around windows and doors for outside, clear... . just a idea.

OK, so here's the update. I decided just to use a small dab of never seize cause I got in a hurry to finish things up. I did take the advice to apply a little bit between the barrel nut and the line to keep it from corroding together. Thanks for that, I wouldn't have thought about that on my own.

Oh and to all of you that doubt the need to do a brake system flush every now and then, crack open a bleeder screw and compare the color of the fluid coming out of it with the color of brake fluid out of the bottle. Wow, what a difference! I plan on cracking open the fronts this coming weekend to clean that side of the brake system out as well.
