brass nipple in brake lines?

I've got my line running to the rear, 3/16 line going from master cylinder to RPV to adjustable proportioning valve. Instead of running a small 3/16 brake line from the rpv to the valve I just connected the two with a br*** ****** about an inch long. Is this acceptable or does anyone with brake/hydraulic knowledge say no to this?

Thanks

 

Br*** is OK only for fittings. You are fine.

 

You are fine.

 

Is that pipe thread and Teflon tape ?

 

"Hell yeah!"

 

The only Issue I have is going through different ID's within the system is a good place for air bubbles to get caught. Would have been better to use a short 1/8 npt coupler with a 3/16 ID to connect the rpv to the bias and run a longer line to the master keeping everything 3/16 ID throughout.

 

Are the tubes double flared? If not you might get a leak.

How do you double flair a br*** ******?

 

All these valves come w/ pipe threads (1/8 npt) and are not flared fittings

Where can we get a coupler like that?

 

Its a standard fitting one can get from the many places that sell braided hose fittings or industrial places like Grainger or Mcmaster-Carr. I've got a box of about 100 of them --come over and I will give you one

 

It's hard to see what kind of coupling that is.
How is it sealing to the other fittings?
You would want something like this between two components.


If its just a simple piece of br*** ****** like this...

It will leak, and possibly burst.

There is a reason why brake line br*** fittings have such thick walls. Brakes regularly operate in the 600-900psi range. In a panic stop you can easily double that.

 

You've got it right, those fittings are designed for pipe tapered threads. I would support the other end of the RPV with a line clamp. Also ditch the teflon tape, that **** has no place in a brake system. The br*** is a soft enough compound to "mash" and seal well when tightened properly.
