are compression fittings ok for brake lines?

[Steve1968LS2]

Installing a rear proportioning valve and it comes with compression fittings.. i thought you were supposed to only use flare fittings on brake lines..

Whats the deal? Are compression fittings fine?



Thanks for the info

I'd be scared of that myself, brake lines can have some incredible pressure under hard braking. But then again, I'm no engineer.

iwould use the doubleflare,as compression fittings on brakelines are illegal in most states,but i doubt one would ever fail.

compression fittings are illeagal in ohio if they are made of anything other than steel. i wouldn't use them on my car because i think they look half assed

We strongly advise against the use of compression fittings...

Thats what I thought.. i noticed that my shop used them and when I asked them they said that the compression fitting came with the Wilwood rear valve.. I doubted this but want to check before I called them out on it

Thanks.. i see flair fittings in my future..

compression fittings in a brake line............HELL NO. If I saw that in my shop there would ass all over the place, I am getting pissed off just thinking about it. 10-9-8-7-6-5-4-3-2-1...OK.

Yea, I was surprised to see it as well.. but the shop is very good so I wanted to make sure I wasnt crazy

They said the fittings came with the Wilwood valve but I doubt that.. musta been from something else...

I 2nd, 3rd, 4th, those comments!!! We use them on our product (in another industry) for the trans cooler lines and have had numerous issues with them blowing off. Brake lines, unbelievable a shop would ever attempt that, absolutely ridiculous.
