Thread: Fitting Wilwood RPV to 3/8" flared line

Tweet

As far as leaks, I posted this a couple weeks ago as I had a caliper leak: http://www.clubhotrod.com/forums/showthread.php?t=45964

Now, the question as to why 3/8" line? Also, are those lines double flared if regular steel brake tube. If they are SS, you really can't do a double flare without some really expensive tools and even then it should be a specially softened stainless. I purchased my entire 3/16" SS brake line and AN fittings from Inline Tube (http://www.inlinetube.com/) and of course got a few pieces that I didn't use. I also had to purchase the 37* flaring tool for the AN fittings. The Wilwood proprtioning and RPV's are from Speedway.

Using the large diameter stuff, while it will work, just adds a mass of extra fittings stacked up to adapt to the 1/8-3/16 brake cylinders/calipers, other line fittings and the prop and RPV's thus opening yourself to those pesky drips. My problem was easily cured after asking my question - it was a speck of dirt, but to date that was the only drip on the entire system.

Well I am torn here because my proportioning valve came with sealed flared to NPT adapters and it works fine so I don't know if I should just use sealer on my residual pressure valves or get flared ones like I probably should have. Is just sealing NPT threads with liquid sealer perfectly acceptable or should I pay $50 bucks for more RPVs? . Hombre- thanks a lot for taking those pictures that helps.

31- so the wilwood rpv's when used with AN fittings just use sealer? If it works like that for AN I will probably just seal what I have.

sunset- it sounds like there is enough hatred for the tape that I will stear clear of it. thanks

Dave- sorry, I meant 3/16" lines...I just had 3/8" nuts on the brain from wrenching all day. Jerry you were correct.

thanks everyone!
