double flare unions (brakes)

Hi guys question about double flare unions. If you do a union and it doesn't leak is it safe to say it's safe? Might be a dumb question but when you tighten them down it is feel and not torque spec so It's in the back of my mind on the safety of the union.

As long as they are double flare and rated for brake lines go for it quite safe

fyi, you can buy a complete set of pre bent coated brake lines for your truck at the dealer for under $115.(if its a 99-07 fullsize truck)




Inverted flares and unions are great. Compression fittings are not.

Re: double flare unions (brakes)

if a double flare union doesn't leak I guess it is considered to be fully 100% safe and correctly done?

Yes. Double wall flare and inverted unions are safe, and they come on a lot of cars from the factory.
