Default Help! pipe tape on brake line fitting?

I have a 90 degree fitting I'm using to direct my brake lines away from the fenderwell headers I have. The fitting isn't really tight until it points straight up.

Can I use pipe tape to avoid leakage on a brake fitting? I'm using DOT 5, if that makes a difference (won't eat paint/silicone)

Quick help is appreciated.

Thanks,

Morgan

if I can't use pipe tape, is there some other form of sealant I Can use?

Thanks

Brake lines are a double flair. You shouldn't need a sealer. If you want you can use teflon tape or teflon sealer in a tube. Reminder-do NOT use teflon tape in fuel line fittings.

Are you using a fitting that is a taper pipe thread or straight pipe thread? You can use the tape or tube teflon.

I thought All pipe threads are tapered. You need to tighten it down to work properly, I see what you mean, with the fitting, once tight its in a wrong postion. Thread tape may help it pull down snugger, and quicker as you thought. Maybe you can use 2 45's to egt where you need to be. But Make sure its tight, remeber that all the line pressure will go through that and that 95% of all friction loss is in turns as 90's or 45's. This means that it will be more prone to leak there than anywhere else.

Nope, they do have "straight pipe" threads.

thanks for the responses guys, I'll try the teflon tape. Just straight line threads. It's pretty close to snug now, I think some tape may finish the job. I will keep a close eye out for leaks though.

Dont worry about the leaks worry about the air you ar sucking in.

i wouldnt use any tape. I would make it work. You have steel brake lines, they can be bent, changed to make it work with the correct setting and seating of the threads and the flairs.

I agree with Kevin, I would not use tape. Brake line fittings have straight threads and the seal is made by the compression at the flare. I have seen at an A/C repair store, copper gaskets for flare fittings. This will alter the amount of turns of the fitting required to get the fitting tight. I would not use more than 1 copper gasket, so you may need to rebend lines anyway.

The pressures in the brake system are far beyond what a sealant can hold.

Has to fit right on the flare or your screwed. That's the only way it will seal.

if you wouldn't put it on a fuel line, you damn sure shouldn't put it on a brake line. Be patient, make sure you are using the correct threaded (compatible) fittings.

What State are you in?

I want to be sure not drive there......

It's a steel line with a double flare, twist the line.

yeah the problem will be addressed without pipe tape. Don, you k now my problem well. The fenderwell headers in this 65 cuda are dangerously close to the master cylinder. I've got everything done except for the outlets at the rear side. I guess I can try to just bend the line, and probably will end up doing that, but I'd love to find a fitting that would work instead to minimize heat exposure.

I use just a little sealer on the fitting to keep the water/moisture out of the fitting/tube. Hoping to keep it from 'rusting'. Hopefully so it is easier to take apart later. Not to seal the fuid from getting out. The double flair is the only thing to seal that.

I heard that aluminum-based grease "white grease" and the like, applied to brake fittings will help with the later removal of fittings. Since the aluminum, even when corroded, is softer than steel, it helps parts just come apart.

Not to beat a dead horse but double flare the lines, use the correct fittings and if things are close/tight put a loop in the line for flex and fit.
