just for my bugeye's restoration i bought a bubble flare tool. i already
had a double flare and a single flare tool . but i found that a number of
the original bubble flare nuts the were from my car had to be modified to be
reused! here's why!
if you ever get to remove a nut from a steel line you will notice the nut is
tapered on the end on the inside of the nut. when a line is over tightened
that flared end stretches out and actually flares out getting larger on the
outside diameter of the nut. the expansion of the bottom of the nut is just
enough you probably would not notice it but it becomes just big enough to
interfere with the threaded hole you will be inserting it into. this causes
all kinds of problems from cross threading to laying the threads over in the
threaded hole, leading to stripping of the threads. you need to carefully
file or with a very small dremel tool remove the flared out portion in order
to relieve the area that will cause problems. i keep all the good reuseable
original fittings and send them out to be replated for reuse. i have a very
small collection of all 3 types of these nuts. yes 3 types . they differ
in the shape of the hex head and some have markings that match the markings
on the original hardware nuts used on these cars too. now the long threaded
nuts that usually come on one end of universal lengths of brake tubing will
work. you can also buy them in bulk at "good" auto parts stores. but in
today's world of remove and replace(not repair) good selections of
automotive specific hardware are becoming rather uncommon.
chuck.
been there broke that....
